Is Mutsumi really a Man in Black, or is he the partner of someone incredibly special? Aki is turned into a teenager by Kururu's new weapon - What If I Can Do Over My Life gun - and takes the opportunity to revisit her youth by going to her children's school.

As other alien invaders on earth are being exposed, the platoon becomes concerned for their own security. Soon an intruder is discovered, but she turns out to be Natsumi's new classmate and the friend of the missing Zeroro. Disappointed and feeling abandoned all those months, the new Dororo breaks off relations with the platoon. In the house, Keroro reflects back on how he, Giroro and Zeroro were childhood friends and included some of the trauma he caused. In the meantime, Dororo and Koyuki have been kidnapped by Viper. The platoon attempts a rescue operation, but is quickly defeated by Viper (who is much stronger than the incomplete platoon).

In a freak lightening accident, the violent aggressive Momoka is spun out of the usually sweet and docile one. The spiked hair Momoka using the vulgar male pronoun "ore" takes over the base and forms the new "Momoka Platoon" and starts the invasion of earth. Defeated, the inept Keroro goes into hibernation. Just as the violent Momoka is ready to push the button to launch the missile, the docile Momoka arrives in time to stop her other self from destroying Earth. They agrees to join back together in one body and will one day declare their love for Fuyuki. Keroro, revived, offers to join them through synchronized swimming.

However, another complete form also emerges—the Keroro-Giroro combination. || Thanks to Tamama`s G-force endurance test machine, Momoka accidentally gets split into two people: Momoka and Dark Momoka.

Members of the platoon and their human allies witness Mois beating up people and taking their money. In disbelief, they try to find clues to Mois's secret activities, but not even her videogram to her father yields any. Hurt that no one believes her innocent and at the same time embarrassed to tell them of her activities, Mois runs out. In pursuit, they encounter a delinquent Mois getting ready to harm some of Natsumi's classmates. To the rescue, Natsumi fights Mois, until another Mois appears. Through a flashback, Mois reveals that she modelled herself after Asami, a brave girl who had once defended the weak.

It's summer, and the school swimming pool is open for use. While Fuyuki has been dreading this all year (he can't swim), Keroro hatches a new scheme to infiltrate the swimming pool and have some fun on his own, resulting in a confrontation with Natsumi in the pool, where Keroro's amphibious advantage over her is exploited to the fullest. After the historic Earth versus Keron Swimming Meet, a second interplanetary competition begins at nighttime, as humans and Keronians duel each other with the scariest ghost stories they can think of. While Fuyuki's little-known talent for ghost stories wins the day, the only real loser here is Giroro, who gets jerry-rigged to a meter and subjected to all the scares (and some physical violence) from both sides. || It`s swimming season at the junior high, and the frogs decide to pay the school a visit. Natsumi`s out to beat the school year record... while Keroro`s out to beat Natsumi! Source: crunchyroll

It's time for another important summer ritual, the family trip to Doinaka Beach, but Hinata Aki is uable to accompany the children due to work commitments, leaving Natsumi and Fuyuki without an adult guardian, until Kururu reveals his latest invention, an age manipulation beam that turns Natsumi into a full-grown adult. An unexpected side effect causes Natsumi to utter 'old-man' jokes involuntarily, while Keroro's hidden angle and true reason for infiltrating the beach is revealed—the super-rare 'Dangale' knockoff model kits, offered as a prize for entering the Swimsuit Beauty Stand-Up Comic Competition. || Since Natsumi`s mom can`t go to the beach with them, the frogs turn Natsumi into an adult to take them. But there`s a catch: she has to enter into a bikini contest doing a comedy routine, and the frogs have her cracking terribly stupid jokes she finds embarrassing! Source: crunchyroll

Low on invasion funds, the platoon takes on food vending and gaming jobs at a festival. Keroro's unscrupulous manners are challenged by Natsumi and they face off at a turtle fishing game. Defeated, the frogs are ready to leave the festival, until Natsumi told them that as long as they are legitimate, it doesn't matter who attends the festival. Stirred by her compassion, Giroro dashes to stop Keroro trump card, but instead find himself, Keroro, and Tamama sent into the air as part of the night's fireworks. The red and green are exceptionally beautiful, but no one can see the dark blue color of Tamama. Witnessing the power of radio, the platoon, minus Dororo, set out to jack all the stations and put on their own programming. Different and novel at first, the radio progam gains a huge draw. However, a poorly impersonated Sumomo-chan by Giroro quickly reverses that and soon listeners turn off their radio one by one. || It`s a summer festival, and the frogs decide not to come. But it turns out that they do show up, after all... as the hosts of rigged games, in order to cheat festival-goers out of Gundam money! Source: crunchyroll

The trip to the beach that Aki promised the children in episode 18 gets put off again due to car trouble, but living with aliens proves to have its advantges, as Natsumi finds out about the Keroro Platoon's high-tech submarine, and begs them to take her to the beach, putting a slight dent in Keroro's newest scheme, to conquer the world through its oceans. Fuyuki comes along, hoping to gather some oceanic research to complete a school project, but winds up meeting a mysterious girl. The girl's true origins are hinted at as the Keroro Platoon's undersea flag-planting activities are met with substantial opposition—the ancient Nontolma civilisation, already angered by humanity's pollution of its oceans, and looking to make an example to the Keroro Platoon. || Keroro`s latest plan is to invade the Earth by planting flags in all of the seas. But as Fuyuki soon discovers, there may be people deep in the ocean who do not want invaders there. Source: crunchyroll

Keroro engineers some falsified invasion footage to send to Keron high command (and make some quick cash on the side) but a sudden city-wide power outage leaves this newest scheme in ruins, as Kururu conveniently forgot to save his progress. Also feeling the heat (literally) is Natsumi, without air-conditioning to beat the rising summer temperatures. Koyuki leaps to the rescue with some traditional summer rituals of her own, while Keroro's backup plan for the next power outage is less than successful. Aki's car trouble has passed, resulting in a brief glimpse at her unique driving skills as the Hinata family (and three Keronians stowing away in the boot) take another field trip, to the countryside this time. Giroro runs off to do some survival training in the forest; Keroro joins Fuyuki for a round of baseball, but gets chased into the forest by a huge dog; Tamama engages a seemingly normal rhinoceros beetle in a martial arts duel; and we meet Grandmother Hinata, who not only learns about the Keronians on her own, but secretly lends them a hand. || The summer heat is unbearable when a power outage puts all air conditioners out of commission. Koyuki teaches Fuyuki and Natsumi the ninja arts of surviving the heat without technology, while the frogs hatch a plan of their own. Source: crunchyroll

Just as a complacent Keroro is happy being unchallenged in his position as the leader, a flying arrow message is shot from HQ: "Tamama is captain."

Power corrupts Tamama and he soon turns into a monstrous tyrant by banishing anyone who disagrees with him, even his most beloved Gunsou-san. What will now happen to Keroro? || Terrible news from headquarters: Tamama is to replace Keroro as their platoon leader! Keroro`s devastated, and Tamama immediately lets his new power go to his head. Will the platoon survive this dreadful new leader? Source: crunchyroll

Keroro steals the Kero Ball from Fuyuki's room, and accidentally clones hundreds of himself, all just as lazy as the original. Kururu's attempt to rectify this situation turns them into mindless drones under Keroro's control, but just as this new power starts corrupting him, Kururu discovers that the malfunctioning Kero Ball may pose a bigger threat to Keroro himself. || Hoping to use the Kero Ball to fix his broken Gundam models, Keroro accidentally manages to copy himself... again and again and again. With thousands of Keroros at his command, he thinks conquering the Earth should be a snap. But these Keroros also have his utterly lazy personality... Source: crunchyroll

Space Detective 556 (Kogoro) and his sister Lavie formally debut in this episode. Keroro takes on this new adversary single-handedly—in a harmless, friendly tussle, as it is revealed that Keroro and 556 are old friends. Life for interstellar immigrants is not an easy one: 556 is unable to hold down a proper job (his habit of collecting junk doesn't help), making Lavie the sole breadwinner - until Keroro tracks down the perfect job, allowing 556 to do what he does best. || Space detective 556 has arrived on Earth, and he`s here to defeat his arch-nemesis, Keroro!

This episode marks the formal debut of Baio Nishizawa, Momoka's father and head of the Nishizawa Group. When Momoka refuses to join her father in Scotland in favor of spending more time with Fuyuki, Mr. Nishizawa flies to Japan to meet with her instead, which gives Keroro the idea of pitting Keron's invasion force with the world-superpower-like Nishizawa group. When Momoka's current bodyguards fail to deter the superior forces of Nishizawa's black ops brigade, Keroro formally intervenes, and the first true interplanetary conflict begins, as Keron's invasion forces go toe to toe against Earth's greatest military superpower. || Momoka`s father is determined to make her move to Scotland with him.

The show shifts its focus back to Japanese culture this week, as we witness the autumn School Sports Meet - yet another thing Fuyuki has been dreading all year (see episode 17). Natsumi on the other hand is excited about running in the three-legged race with her mother Aki - until she learns that work commitments have held up Aki yet again. Keroro schemes to win Natsumi's gratitude by infiltraiting the sports meet with Giroro and stalling the events until Aki can make it, while Tamama and Dororo head to Aki's office and attempt to speed up her work - but both efforts seem doomed to failure, forcing Giroro to act on his own. || Natsumi can hardly wait for Sports Day, because her mom is coming! But then a last-minute work emergency holds her back, and the frogs wind up deciding to try all manner of crazy things to delay the events until Natsumi`s mom can make it. Source: crunchyroll

Keroro receives a letter from his father, rumored by many to be Keron's most fearsome soldier and commander, now planning to visit Earth. Keroro is forced to engineer a massive coverup for his lackluster 'invasion' of Earth, or risk his father's wrath. Keroro's newest scheme involves creating his own onsen, by digging a new hot spring from the Keron underground base. After drilling underground in the Magma Swimmer drill tank, the Keronians discover buried alien relics left behind by an ancient invasion force, and chaos erupts as the ancient machines reactivate on their own and attack the Keronians - the ensuing battle leaves the Magma Swimmer exhausted of power, and the Keronians without any way to return to the surface... || Keroro`s father is coming to visit, and inspect his son`s progress in invading Pekopon!

The platoon, having never experienced snow, joins the humans in a snowball fight. To make the game more interesting, they designate hostages and a time limit to capture the enemy flag and free their comrade. Paul and Giroro get caught up in the game while everyone else has moved onto building snow creatures. The narrator's reading of the script upon introducing Kururu makes him want to prove how much of a bad ass jerk he really is. For each victim, he devices a unique plan. All attempts to reason with him fails, even threats of violence. However, it's Mois' pure and innocent heart that finally cracks the depressing jerk. He can't stand her shiny innocent eyes. || Keroro decides to use snow to conquer the world, but he discovers that it`s very cold and uncomfortable to go out in. So the frogs and humans split into teams and hold an epic snowball fight instead! Source: crunchyroll

It's time for the school drama club's annual production. Natsumi's two recurring classmates Yayoi and Satsuki beg her to help them in their stage production of Peter Pan, and while Koyuki relishes the idea of performing alongside Natsumi, it turns out that stage acting is one of the few things Natsumi is completely hopeless at. Keroro offers his assistance yet again, subjecting Natsumi to all forms of stage training - but just as she gets her act together, the sight of Saburo in the audience watching her performance reduces her to the same hopeless state she began in. Keroro intervenes in full view of the audience, and rapidly escalating chaos ensues. Also in the audience was one of the three new characters debuting - the Kissho Academy Newspaper Club aka KGS. It turns out that they have been carrying out their own investigations on every one of the Keroro platoon's school infiltration shenanigans, down to Fuyuki's connection to these alien invaders, and they plan to break into the Hinata household to search for evidence - but Keroro, now grounded and barred from Gunpla-shopping after being spotted by the KGS in public, has every intention of taking the battle to them. || Natsumi`s been cast as Wendy in Peter Pan, and she is a horrible actor. Keroro tries to give her acting lessons, but there`s not much he can do when she suddenly freezes on stage! Source: crunchyroll

We meet Taruru, one of Tamama's martial arts students, who lands on Earth to visit his number one idol Tamama - who's been secretly feeding a pile of hogwash to the boys back home, embellishing his own image while deflating everyone else around him (except Keroro). Only after Taruru leaves do the three remaining Keronians, the Hinata children, Paul and Momoka gather around Tamama and exact some overdue justice. Momoka hatches a plan to make herself more physically attractive to Fuyuki, and Tamama enlists Keroro's assistance in this matter. A large number of Kururu's inventions get showcased here (and tested on Giroro, with painful results), but just as Momoka loses all hope, she chances upon something new - Hinata Aki DNA Pills, which prove a little too effective... and not just on Momoka... || Tamama has been making up lies about all the others in letters home to make himself look good... but now one of his students has dropped by to visit, and is blabbing about those lies right in front of each person!

It's now up to Natsumi to go out and bring her stupid frog back home. || Against Natsumi`s orders, Keroro goes off riding in his brand new flying saucer that he bought for a steal online. Unfortunately, the thing breaks down, and he`s lost by himself. Will he ever be able to find his way home again? Source: crunchyroll

Keroro's latest scheme involves recruiting Earth's animals into his invasion army, with the help of Kururu's 'We All Live Together' beam gun that turns animals into humans. The scheme predictably backfires, as none of the animals are interested in joining Keroro at all - even the mighty Bengal Tiger, spoiling for a fight from the moment he is turned, is against the idea of going to war. When Keroro unwittingly reveals his intention to replace the Keroro platoon with animals, the normally loyal soldiers stand aside as Keroro raises more animals than he can lay down. The cat that Giroro brought in from the rain has now become his most loyal companion, so much that it's started to express great jealousy in Natsumi's presence. When a distressed Giroro wants to give Natsumi a pinecone pendant but can't, the cat feels his distress and wants to help, but also can't... until the 'We All Live Together' beam gun winds up in its paws. || Keroro decides to turn a bunch of animals human and try to get them to join his platoon.

Witnessing the merchandising power of the 'Admiral Geroro' anime, Keroro hatches a new scheme to conquer Earth throuugh the creation of his own anime - but the actual process, from storyboarding to artwork to animation, prove far too troublesome and frustrating for the Keroro platoon to handle. They pay a visit to an actual animation studio, picking up the tricks of the trade, and after returning to work, the final product is ready for viewing - but Keroro decides that more work is needed, and returns to the research & development stage (the fact that said final product turned out to be quite horrible isn't even brought up). || In order to take over the world, the Keroro Platoon decides to create an anime that will capture the hearts of children everywhere. But they have no idea how to go about it! Source: crunchyroll

After experimenting with several types of fortune-telling, Momoka learns that her romantic destiny with Fuyuki will be realised in an onsen. Thus she engineers a scheme of her own, allowing Fuyuki to 'win' an onsen trip for the whole Hinata family and one guest... problems arise when Keroro and Koyuki have their minds set on that guest ticket at the same time. While Keroro is easily dispatched with the task of solving a Rubik's Cube, Kururu forces Momoka and Koyuki to battle each other for the guest ticket, and tradition clashes with technology as Koyuki pits her ninja skills against Momoka's new robotic battlesuit! Fuyuki is late for school, while Keroro is fleeing Natsumi's wrath after breaking her mug - the two meet each other on a shortcut to school. With Mutsumi standing in for the narrator, the simple act of walking down this seldom-used lane, filled with old memories and new discoveries, turns into an evening to remember. || Momoka`s horoscope says that Fuyuki will have the chance to invite her to the hot springs today, and if she misses this chance, her love is doomed.

So, will the party work? || Natsumi`s birthday is coming up, but she claims she doesn`t like presents or parties, which she defines as "too childish." Desperate to do something to celebrate it, Fuyuki and the Keroro Platoon decides to throw a huge birthday party to surprise her... which might or might not be a huge disaster. Source: crunchyroll

Winter looms and temperatures take a dive - Keroro is introduced to Fuyu-Shogun, the General of Winter, which is really just a term given to the cold air currents originating from Siberia, but Keroro visualises Fuyu-Shogun as something resembling Demon Emperor Arago from Yoroiden Samurai Troopers. When the simple act of stepping out the front door proves too much for Keroro, he decides to go through endurance training to combat the cold front, and subjecting the Hinata children to the blizzard simulation against their will only shows them to be far more resourceful than Keroro was. When Tamama tells Momoka about the blizzard simulation and the accidents that followed, Momoka offers to let the Keroro platoon continue training on her private snowy mountain resort - with the real intention of getting closer to Fuyuki, as usual. While the Keroro platoon starts trekking up the hazardous snowy mountains, Momoka puts her own plan into motion, activating the mountain resort's snow generators - but Kururu chooses to activate his private satellite's weather manipulation function at the same time, and the mountain resort is plunged into an artificial ice age. || The bitter winter cold has begun, and Keroro can`t stand it. But he has to be able to go outside to buy Gundam models! So he decides it`s time for the platoon to undergo special winter training.

Keroro's latest scheme involves making Dororo give ninja lessons to raise money for the platoon. When nobody actually signs up for said lessons, Keroro makes the rest of the platoon learn Dororo's ninja arts instead - but none of them seem to be serious about learning anything. To make matters worse, 556 sees their ninja lessons as competition against his own attempt to give Space Detective lessons, and tries to shut the operation down. After Natsumi's radio show was interrupted by 556's invasion, it gets interrupted yet again by a pterodactyl flying into her room - it turns out that Keroro, inspired by a certain Hollywood movie, is using Keronian technology to clone dinosaur DNA and open a theme park featuring said dinosaurs. Using Kururu's mind control apparatus, Keroro has tamed a tyrannosaurus into doing his bidding, but an accident causes the mind control cone to come off the T-Rex's head (and onto Giroro's head), causing it to run wild through the underground base. || In order to earn money, the Keroro Platoon volunteers Dororo to teach "how to be a ninja" classes. But nobody shows up! So they decide to take the classes from him themselves. Source: crunchyroll

As part of a galactically-broadcast Candid Camera-esque program, Keroro plays a prank on Giroro, with the help of a Pekopon suit modelled after Natsumi, with Sumomo at the controls. Hilarity ensues as Giroro distracts himself from faux-Natsumi's advances with physical training and weapons maintenance - causing an exasperated Sumomo to attack Giroro, and incurring the wrath of the real Natsumi when she sees her own towel-clad self leaping across town. When she opts to stop them on her own, Kururu gives her his latest invention - the Natsumi battlesuit. Natsumi finds herself stuck with Kururu's battlesuit, which has a tendency to activate when anyone nearby utters something even remotely sounding like the attack command. When the invade command kicks in, the battlesuit AI takes over Natsumi completely, causing her to destroy anything the Keroro platoon sends after her. Giroro is forced to confront her as well, and Kururu gives him the battlesuit deacivation code... "Natsumi, my love. Kiss me tender and hold me tight, forever!" || The Keroro Platoon thinks it will be hilarious to pull a prank on Giroro: they stick Sumomo in a Natsumi suit, and have the fake Natsumi hit on Giroro outrageously. But... Giroro might not be the wisest person to play pranks on. Source: crunchyroll

Keroro hatches a new scheme for the Christmas season, but Dororo and Tamama refuse to go with it for different reasons. Tamama tells Keroro about Santa Claus, who knows when you've been naughty or nice, prompting Keroro to carry out investigations on Santa Claus. Unfortunately the Christmas season of cheer and good will begin to take effect, as Keroro's remaining loyalists Giroro and Kururu desert him as well. Left to his own devices, Keroro begins to discover the Christmas spirit in a way he hadn't really expected. Keroro is unusually hot-blooded about spring-cleaning time, taking charge of housecleaning operations in the Hinata household, and imparting valuable tips and tricks to the Hinata family. At the end of the day, human and Keronian alike sit down for noodles, listen to the bells, and welcome the new year. || Christmas: the perfect time to conquer the Earth!

It's the first episode of the new year - and the Keroro platoon's New Year celebrations involve subjecting Giroro to different forms of abuse for some reason. While discussing new year resolutions, Angol Mois is reluctant to reveal hers, until a reaction in her alien physiology, triggered by Keroro's suspiciously glowing 'red bean soup', causes her to go completely berserk. The Keroro platoon receive some mail from well-wishers at home, the Keronian children - and at least one reminder from Keron high command, ordering Keroro to submit a large amount of overdue homework immediately. With the help of his loyal troops, Keroro overcomes every possible distraction and completes the homework on time... but one last obstacle looms on the horizon... || Happy New Year! Keroro makes a special meal to celebrate the new year, but he may have picked the ingredients poorly, because Mois goes really strange after eating it. Or, like, super danger? And then Keroro forgets to do his homework... Source: crunchyroll

Kururu develops a seemingly innocent board game which shrinks Natsumi and Fuyuki and places them in the middle of the action. Landing on any rewards and penalties on the squares turns them into reality, and while Fuyuki gets sidetrips to assorted wonders of the world, Natsumi winds up executing one impossible stunt after another. The final square is revealed to trigger the Keronian invasion, but this scheme falls apart as the square before it summons Angol Mois' father, the original Destroyer of Worlds! Inspired by the sight of 556's attention-grabbing antics, Dororo asks him for help - and is fed with 556's vitriol and drive for life. Returning to the Keronian base, a pumped-up Dororo rallies his fellow soldiers, pushing them through all forms of training in order to master a new combined battle technique - but all his efforts to strengthen his own presence fall flat, as the other four promptly forget about him the moment they put their training to actual use. || Keroro, Kululu, and Tamama invite the humans to play a board game... with the fate of the Earth at stake!

Inspired by watching World Cup soccer on TV, Keroro plans on pitting the superior Keronian forces against the best Earth has to offer - on the soccer field. Answering this challenge on the planet's behalf is Paul Japan, a team of top soccer players handpicked by Paul to defend the pride of soccer as a human sport. Tamama makes friends with a boy he sees practicing his soccer moves everyday. He joins the boy in his daily routine, and even teaches him his trademark Jealousy Ball, adapted for soccer into the Jealousy Shoot - which destroys the boy's old soccer ball by accident. Fortunately the vast resources of the Nishizawa Peach Group fix the ball exactly as it was. Eventually, the boy learns to shed his defensive mindset and play better than he ever could, and Tamama has someone he can truly call a friend. || To prove their superiority over Earthlings, the frogs decide to form a soccer team, and go up against the best soccer players on Earth!

nspired by a Japanese fairytale of the Red and Blue Oni, Keroro devices a plan to win over Natsumi. Playing the Blue Oni, a bad guy who was only doing so to bring happiness to his friends, he tries to force a romantic situation between her and Giroro. However, nothing goes to plan and the special romantic moment is shared by the Red and Green Alien instead. Deciding that it is better to be the Red Oni, Keroro is quickly pelted with soybean by Natsumi on Setsubun. Wanting revenge, he has Kururu turn her into an Oni girl via the Oni ray gun. Now all soybean products are attacking Oni Natsumi and not even Giroro can save her. Being cornered, Natsumi almost yields to Keroro until Fuyuki reveals that Natsumi is a Thunder God. || Taking an idea from a fairy tale, Keroro thinks it would be a good idea to manipulate Natsumi to fall in love with Giroro and then start to like Keroro better. Needless to say, the operation does not go so smoothly. Source: crunchyroll

Kururu proposes a formal competition to compare human and Keronian physical proficiency. Natsumi, still seething after the events of episode 17, accepts Keroro's challenge, whereupon Keroro picks Fuyuki as his opponent. Momoka's snowy mountain complex forms the backdrop as Keroro and Fuyuki go to battle in winter sports, but one unexplained phenomena after another (a freak updraft, a stray missile, a bobsled rail coming off for no reason) threaten to throw the competition into disarray. All the happenings in the first act are finally explained - Kururu's true intention was to build and test his new giant robot (which eager test pilot Hinata Aki dubs the Autumn H), without unnecessary distracions from the Hinata children and his fellow soldiers. Unfortunately Aki goes crazy with the robot's weapons, forcing Kururu to move out in the Kururu Robo to bring her in, resulting in all the unexplained phenomena from the first act. || It`s time for the Winter Olympics! Or at least, a bizarre version of it, where Fuyuki and Keroro compete to prove whether Earthings or aliens are more powerful. Naturally, Kululu goes out of his way to sabotage them both and cackle maniacally... Source: crunchyroll

It's the day before Valentine's day, and Keroro, inspired by the sales of chocolate on this occasion, plans on cashing in by manufacturing and selling traditional ikinari dango or sweet potato snacks, as a substitute for traditional Valentine's Day chocolate. Unfortunately, all the marketing and promotional power of the Keroro platoon fail to overturn international tradition, and Keroro is left with stacks and stacks of ikinari dango that will haunt him for many episodes to come. Valentine's Day arrives at last, and whether it be chocolate handmade from store-bought ingredients or coca flown from Ghana by the Nishizawa Peach Group, Natsumi and Momoka are on a sacred mission to give their chocolates to the men in their lives (Saburo and Fuyuki respectively), but each has her own obstacles to overcome - Natsumi's own nerves get the better of her at each turn, and Momoka watches helpless as Fuyuki receives Valentine's Day chocolate from other girls (Fuyuki himself has a different sort of problem, in the form of the combined jealousy of the menfolk of Kisshou Gakuen.) || Keroro has a brilliant idea: he`s going to sell instant dumplings, instead of chocolate, for Valentine`s Day! Nothing could possibly go wrong with that plan... Source: crunchyroll

Spooky happenings take place in the Hinata household, and Natsumi is first to point fingers at Keroro - but Keroro's air-tight alibi leaves everyone puzzled. This somehow leads to bigger unexplained manifestations, and finding the logical explanations for them leads to one final manifestation, as the Hinata house ghost is sick and tired of everyone forgetting her existence by simply explaining it away. A ghost with a grievance is a powerful thing indeed, as the house ghost spirits Natsumi and Keroro away, and her long and painful history is revealed at last - as a child, she found a kappa (an amphibious Japanese demon), befriended it, and was deemed a heretic and locked in a vault by her fellow villagers for it... || Upset at being forgotten by everyone, the ghost girl spirits away Natsumi and Keroro. What is her backstory, and will she ever find the light? Source: crunchyroll

The story begins with Natsumi inviting Koyuki to spend Hinamatsuri, the Japanese Girls' Festival, at the Hinata household. Keroro intervenes once again, hoping to 'spice up' the traditional festival in his own way, and Kururu unveils his newest invention - Kururuko, a magical girl style Pekopon suit, its perfect human likeness spoiled by Kururu's attempt at a girly voice from inside it. Kururuko then proceeds to send the humans into a holographic realm, introducing them to Hinamatsuri, Outer Space style. Debuting in this episode is Dance Man, the white-suited afro-coifed singer of the Afro Gunso closing theme... and Dasonu Maso, his alien bootleg version. The story begins when Keroro tricks Natsumi with what appears to be a Dance Man concert ticket, but ripping off the counterfoil summons Dasonu Maso from deep space, and Natsumi is subjected to the truths of Dasonu Maso as well as the threat of her very own afro.... || It`s Girls` Day, and Keroro has a great idea to liven things up! This doesn`t bode well. Then Natsumi gets a ticket from Kululu to see her favorite singer perform live. Unfortunately, he turns out to be an alien imitator... Source: crunchyroll

Springtime rolls in at last, and a form of seasonal laziness begins to affect all people - which inspires Keroro's latest scheme, to channel the energies of the world's laziest lifeforms and use it against the people of Earth. Kururu creates a reactor chamber to house this 'Keron March Energy', and a successful test with 556 as the subject is run, but things go horribly wrong when Kururu opens the reactor to let out 556... and all the Keron March Energy at the same time... Keron March Energy spreads rapidly throughout the city, and it's up to Fuyuki, protected from the ominous fog by his diving suit from episode 20, to put a stop to this. Making his way through the underground base, Fuyuki uncovers one cryptic clue after another, and finally locates Keroro - trapped by the now self-aware Keron March Energy (bearing a strange resemblance to Ayanami Rei of Neon Genesis Evangelion), which threatens to bring about the end of the world with March Impact. || Kululu`s latest machine has the ability to steal energy and make people into hopelessly unmotivated, sleepy individuals. This seems like the perfect way to conquer the Earth! Unfortunately, all does not quite go according to plan. Source: crunchyroll

Kururu passes on to his platoonmates his new 'life policy' - do something you don't normally do. After seeing Natsumi and Fuyuki react to Kururu's revised behavior with gratitude, the other Keronians take to this new attitude with great zeal - Keroro in particular gets the wrong idea and winds up doing a lot of needless and ultimately annoying things. Even his personal attempt at triggering the Pekopon Invasion goes awry when his congenital ineptitude gets the better of him. March 14 is White Day, the day that boys who received Valentine's Day chocolates (re. ep 45) get to give something back, and Momoka gets a box of cookies from Fuyuki, which she proceeds to display in her private vault (the cookies that is). However Momoka is looking forward to something more - the perfect date with Fuyuki. Paul enlists the Nishizawa Peach Group's vast resources to create the Super Version Simulator, a virtual reality chamber to determine every possible outcome of Momoka's date with Fuyuki, taking into account every possible situation, down to possible interference from practically every other character in the show... save for one... || Kululu`s being unexpectedly nice! What in the world could have caused that?! And then it`s White Day, and Momoka has the ultimate plan... Source: crunchyroll

After doing some digging around in his tent, Giroro comes across a DVD of the Keroro Platoon's press conference before they left for Earth. While watching, he realizes just how far the Keroro Platoon has fallen from their original duties. The Keroro Platoon decides to go back to its old ways and take over the Hinata house. But how can they get past Natsumi Hinata, the demonlord of the house? Or will a serious fever take her down for them? An irregular fever causes Natsumi to go bedridden, with the Platoon fearing for her life. Giroro's love for Natsumi gets the best of him once more as he battles with a Space Cerberus. || Giroro`s humiliated when he comes across some old footage of him insisting he would never fall in love with a lady soldier on the other side. He decides that, no matter how he feels about Natsumi, he has to conquer the Earth right away! But then Natsumi gets sick, and he`s forced to re-evaluate where his priorities lie.
