The last episode ended with a Seki named Mahiru showing up and grabbing Kyohei's arm. We step aside from the action for a second to Kuuko and Aki, who are meeting a man named Hirashiro Takeshi, a Diet member from the village. Back to the rest of the gang, where Mahiru is all over Kyohei, prompting Koushiro to tell her to go back to the village. Mahiru gets angry and lashes out with her Kakashi, Magatsuhi, but Koushiro defends Hibino and starts to battle with her. However, Koushiro's Kakashi is captured . Moyako tries to stop the fight by threatening to stop maintaining Magatsuhi, and while Mahiru is distracted, Kirio and Utao tag team it up to take out Magatsuhi's barrier and free Uwazutsu. Taking another step away from the action, Hirashiro explains to Aki that he is trying to bring the Kakashi out into the light to benefit people outside of the village. However, the elders would never approve of that, so he needs to get rid of them, and for that, he freed Aki. He asks Aki to join him, but at that moment, Mahiru bursts into the office, spewing her hate for everyone. Aki starts to fight her, but Magatsuhi is able to get the barrier up right as Aki just misses her with his attack. However, Mahiru doesn't kill Aki because she doesn't want to upset Kyohei. Koushiro meets with Kyohei to ask him about his connection with Mahiru, and Kyohei starts to tell the story of eight years ago, when he and Aki met Mahiru. They find a cave and go in to explore it. There, they find a strange Kakashi covered in moss. The Kakashi activates and captures Aki, but Kyohei cuts him loose with Kukuri. The three Seki team up to try to fight it, but are unable to do any real damage. Aki manages to get a hit in, but it's not deep enough and Kuramitsuha takes a beating. However, Kyohei is able to get a clean hit in while it's charging its laser. Aki realizes that the Kakashi can consume minds, which is why it could move without a Seki. The Kakashi is still moving, though, and it blasts all of them. Kyohei tries to drag the other two away, but the Kakashi continues to attack. Kyohei tells Koushiro that this is all he can remember and that he woke up to see the Kakashi destroyed. He tells Koushiro that his mind has been broken since that day. However, Mahiru, who is reminiscing about this incident at the same time with Aki, reveals that Kyohei opened Kukuri's left hand that day and saved the two of them.
