Rokuro Enmado has great talent as an exorcist, but because of trauma in his past he has given that pursuit up. That's when he meets Benio Adashino, head of the famous Adashino exorcist clan, who has moved to Tokyo from Kyoto. What will become of these two after their fateful meeting?

Benio has moved into the Seika dormitory, which puts her into conflict with Rokuro after their unpleasant first encounter. Soon a strange individual arrives at the dorm clad only in a pair of underpants. This turns out to be the leader of all exorcists, the Chief Exorcist Tsuchimikado Arima. After inviting the members of the dorm to the Five Mirror Chamber, he asks Rokuro and Benio to battle in front of exorcist authorities from around Japan. Benio wants to test Rokuro's strength, but he still wants nothing to do with being an exorcist.

Benio quickly becomes the center of attention after transferring to Rokuro and Mayura's middle school. When a Kegare attacks between classes, Benio decides to leave while Rokuro claims that their studies should take precedence over exorcist duties. But is that how he really feels?

When Ryogo runs into more trouble than expected during a Kegare exorcism, a desperate Rokuro turns to the one person he thinks can really help: Benio.

When the kids from an elementary school soccer team are suddenly transported to Magano by Kegare, Rokuro joins Benio, Atsushi, and Shinnosuke to go to Magano and save them. But in the middle of the battle, painful memories overwhelm Rokuro, and he's unable to fight. Just then, one of the highest ranking Exorcists, the "Vermilion Bird" of the Twelve Guardians, Ikaruga Shimon, appears.

With Benio constantly leaving school for no given reason, Mayura starts to worry about her new classmate. And Rokuro starts getting back into the swing of things by joining the others on a regular Kegare exorcism.

Arima returns to Tokyo to give the Twin Star Exorcists a trial to test their skills. But it's not the kind of test they were anticipating, with an unexpected reward.

Mayura and Benio debate whether or not Rokuro should continue fighting, and an unpleasant figure from Rokuro's past arrives to test his renewed dedication to being an exorcist.

With the truth about Rokuro exposed to Benio, the Twin Star Exorcists are confronted by someone who shares a connection to both of them.

After being confronted by Yuuto, the Twin Star Exorcists are desperate to get stronger in preparation for future battles, but Benio's old master Subaru has a different kind of training in mind.

Subaru of the Twelve Guardians thinks that Benio and Rokuro need to understand each other better, but the Twin Star Exorcists aren't convinced and insist on conventional combat training. The debate comes to head in the form of a game of hide and seek: if Benio and Rokuro can track Subaru down before sunset, she'll provide the training they're asking for.

Benio and Rokuro square off against the massively powerful Kamui, but are hopelessly outmatched. What makes this Kegare so uniquely dangerous? And can the Twin Star Exorcists survive?

Benio has a vendetta against the incredibly powerful Basara, Kamui. Rokuro tries to reason with her as she insists on fighting him no matter what the cost. Can the Twin Star Exorcists overcome their most deadly enemy yet by working together?

It's Tanabata at the Seika Dorm, and everyone is reminiscing while they think about what their wishes for the future will be.

After harsh words from Seigen, the Twin Stars are frustrated with how powerless they feel. Mayura decides to help cheer her exorcist friends up, in spite of a warning from her father...

Seigen attacks Yuuto, which proves useless. Yuuto fatally wounds Seigen who casts a barrier around the Twin Star Exorcists and the fainted Mayura. Seigen resolves to blow himself up; however, Rokuro and Benio escape from inside the barrier, which again Yuuto congratulates. Seigen is saved minus one arm and Rokuro manages to land a punch on Yuuto who is shocked. He then announces that he will wait for Rokuro's answer (whether he will join Yuuto on the dark side) at a place where there are precious memories for the both of them: Hiinatsuki Dormitory. Seigen and Mayura were hospitalized: Seigen undergoing surgery and Mayura still unconscious. Jissama has received information that the Twelve Guardians has been mobilized to destroy Yuuto and he gives Rokuro a package that Seigen had been wanting to give him. Inside, there is the black exorcist uniform that Seigen wore. Rokuro wears the uniform and announces to Benio that he will defeat Yuuto even with the Twelve Guardians mobilized.

Rokuro has sworn to defeat Yuto. But... how? The Twin Star Exorcists look at the facts and try to find a way to strengthen their odds against an opponent that outclasses them in nearly every way.

It's all been leading up to this. With their new Resonance abilities, the Twin Star Exorcists take the fight directly to Ijika Yuto. Will it be enough to defeat the twisted, evil exorcist?

Yuto has been dominating the Twin Star Exorcists so far, but can help from an unexpected source change the course of their battle?

Two years have passed since their battle with Yuto, and the Twin Star Exorcists have gotten better with age. But when they find something unexpected in Magano, there's no telling what it could mean for their future.

With the secret behind the Dragon Spots and Sae's origin revealed, the path to salvation is clear. But are the Twin Stars willing to part ways with the girl who's become like a daughter to them? And if they're not, can they help the Twelve Guardians resist the flood of Kegare coming through the Dragon Spot?
