True Calendar (T.C.) 71 - A new age where 70% of the human population lives in space. Haruto Tokishima lived an ordinary life as a high school student in the division known as “Module 77”—until the Dorssian military begins their sudden invasion!

Enraged by his loss, Haruto uses the Valvrave to seek vengeance against the Dorssian Military. But an equally furious A-drei stands up against the attack and quickly overwhelms the inexperienced fighter.

L-elf is held in interrogation but he manages to escape. Haruto makes a triumphant return and is considered a hero by the masses for taking on the Dorssian military. Haruto has a meeting with Senator Figaro.

L-elf tells Haruto to make a pact with him. ARUS kidnap Haruto and attempt to escape without saving the students of Sakimori. Shoko imparts the plans of ARUS to the student council. Not willing to depend on others, Sakimori students declare independence.

Since Shoko declared independence, the students of Sakimori have been leading a carefree lifestyle. All of a sudden, the power goes out. Finally, the students manage to turn the power back on, and they broadcast a video of themselves singing a song.

Saki goes inside the Valvrave in hopes of becoming a famous singer. She bites Haruto on the neck and then pretends to be his little sister. Dorssia forces start an attack despite Shoko's threat, while Saki pilots a female robot, which she named Carmilla.

L'elf hands Shoko papers which include a plan for the military development and territorial expansion of JIOR. A-drei, Q-vier and H-neun interfere and Rukino tries to stop them. Haruto possesses L'elf to use his Valvrave. Will he be able to help Rukino?

Students of Sakimori are mourning for Aina. L-elf is held prisoner by the students, and he recalls the time he first met Lieselotte. Sakimori is attacked by the Dorssians. Haruto and Saki go out to battle against them, trusting L-elf's tactical advices.

L-elf has the students perform military training and establish plans to increase the defenses of Module 77. Meanwhile, Raizo is caught once again trying to hijack one of the Valvraves and is put into prison, while Kyuma dedicates himself to training in order to avenge Aina's death. Soon after, Module 77 is once again under Dorssian attack. Haruto and Saki engage the enemies unaware that they are being drawn away from the base and giving an opening for a second invading force. With Haruto and Saki occupied fighting A-Drei's party, a shortage of power renders the module defenseless until Kyuma takes control of the blue Valvrave and starts a counterattack. However, Kyuma finds himself in a disadvantage until the yellow Valvrave, piloted by Raizo, appears to assist him and they manage to drive away the enemies. After the battle, Haruto confronts L-elf as he did not warn them about the enemy's strategy, but he is calmed down by Kyuma who claims that he chose becoming a Valvrave pilot by his own will just like Raizo. Sometime later, Takumi is confronted by L-elf and confesses that except by Rion, all teachers and personnel in module 77 were part of the military and involved with the Valvrave project and unbeknownst to them, the students were also part of it.

While in the holding bay, Takumi explains to L-elf the circumstances under which Sakimori High School was created, for Project VVV which is virtually a JIOR military initiative. As Module 77 continues to progress towards the moon, Haruto and co. discuss the terms of keeping their possession ability a secret while Shoko continues improving her relationships with their fellow schoolmates. At the same time, Rion announces that Module 77 will hold elections for a new Prime Minister that will handle their public affairs once they get to the moon, with herself along with Raizo and Satomi running as well. L-elf surprises Haruto by volunteering to take care of the election affairs since having an appointed leader would help meet his goals. Later on, the frequency at which the foreign gene within Haruto's system tries to take over increases, as noticed by Saki, and she opts to kill him should he resort to physically harming their fellow students. At the same time, Shoko is pressured by their schoolmates to run for Prime Minister, but she uncharacteristically refuses. Cain also plans for a final attack of Module 77 before they reach the neutral grounds of the moon. Haruto later beats himself up for not realizing that Shoko already knew that her father might be dead, and vows to find him and end her pain. This gives Shoko resolve to enter the election and is able to sway the popular vote by proposing a cultural festival upon reaching the moon. Simultaneously, as Saki tries to talk Haruto out of his decision he suddenly begins to regress into a beastly state, becoming completely overtaken by the foreign gene and engages in sexual intercourse with her, who finally realizes they have been cursed by the Valvrave power. When Haruto awakens, horrified at what he had done, Saki checks the WIRED network and tells him Shoko won the election.

Ryuuji Sashinami is brought before Dorssian 54th Military Tribunal on the charge of touting JIOR neutrality while constructing Valvrave weapons. At the same time, Shoko expresses her optimism for their future on the Moon to Akira. Raizo begins practicing with the Valvrave Three in order to lengthen its operation during combat. Meanwhile, Shoko along with her fellow students who now form the New JIOR government gather for a photoshoot. Here, Akira opens up to Shoko by speaking for the first time through a phone call. Although she soon erupts into a fit of panic after being overwhelmed by everyone's excitement to hear her speak, which is reminiscent of a traumatic experience she had in the past. Elsewhere, Saki and Haruto go around the city ruins for the day, visiting a bar and a movie theater. As Saki's feelings of wanting companionship are returned by Haruto, they are interrupted as Module 77 meets the Dorssian blockade en route to the Moon. As Module 77 prepares for battle, L-elf has the Valvraves move the Module away from the blockade, causing the Dorssians to peruse and break formation which coincides with his plan to have the Valvrave One's Harakiri Blade destroy them in one strike. Meanwhile, Admiral Delius Wartenberg threatens Ryuuji in an attempt to get Shoko to surrender. While she struggles to decide on a course of action, Valvrave One's Harakiri Strike annihilates the Dorssian forces, subsequently killing Ryuuji, much to Shoko's agony. Meanwhile, Cain, having predicted L-elf's course of actions, makes a surprise attack beneath Module 77, infiltrating it with a squadron of Dorssian soldiers and using a drilling Mech to begin ploughing straight through the heart of the Module. Haruto has Saki return him to the Module. As Saki laments on Haruto's actions to save Shoko, he surprises her with a sudden marriage proposal.

In the year 211, Saki is telling the story of the Magius to a boy who looks like L-Elf. Back to the present, Saki calmly rejects Haruto's marriage proposal and proceeds to help the other 2 Valvraves hold off the Dorssian forces. Meanwhile, the drill that was sent into the Module is moving up through the space with the intention of releasing poison gas into the atmosphere of the Module. L-Elf receives a call from Haruto and meets up with him to try to defeat the Dorssians. Satomi calls Shoko and asks her to save his sister, Akira, who is trapped in the school. Akira, who overhears this conversation, tries to stop Shoko but to no avail. Shoko was knocked unconscious by the drill while trying to get to Akira, and this prompted Akira to face her hears of being bullied and come out into the open to save Shoko. Facing a dead end due to the damage by the drill, she almost gave up until a crack in the debris reveals Valvrave unit 6. Akira climbs into it and confirms herself to be the 6th pilot of the Valvraves. She saves Shoko and using the Hummingbird equipment hacks the drill and stops it short of the surface of Module 77. Haruto and L-Elf, meanwhile walks into a trap laid by Cain and A-Drei who are watching Valvrave 1. Cain and A-Drei almost made it out when Akira, piloting Valvrave 6 appears and is sending the drill in the opposite direction. Haruto and L-Elf takes this opportunity the break free and get back into Valvrave 1. As they try to kill Cain and fails to do so, Cain tells them that their efforts to kill him are futile. Cain makes it to the unfinished Valvrave 2 and plants Blue, a life unit into it and pilots it. L-Elf wonders what Cain is if he is not human. A cutscene reveal the Magius, an organization which governs the world from the shadows in a meeting which involves representatives from ARUS and Dorssia, and at the same time Cain reveals he is from that organization.
