Bruised & Battered Denji and Power visit Aki in the hospital and tell him that only Kobeni and Madoka survived the assault, besides them. Aki mourns Himeno's death, before Kurose and Tendo arrive to ask for his report and if he wants to continue his service. He says he wants to avenge his family and Himeno too now, so Kurose and Tendo demand he form a new contract with a more powerful Devil, since the Fox Devil refused to work with Aki now. Aki is then visited by Himeno's sister, who gives him letters Himeno sent home, about her trying to save Aki from this job. Makima takes Denji and Power to the cemetery to meet with a Devil Hunter from Division 1, Himeno and Aki's trainer, revealed to be Kishibe. This self-proclaimed strongest devil hunter begins training them to become stronger, by killing Denji and nearly killing Power repeatedly. After an entire day and dozens of deaths, Kishibe sends them home. The next day, Denji and Power carefully plan to trap Kishibe, but he effortlessly beats them again. Tendo and Kurose take Aki to a lock-up where all the captured devils are kept alive, where Aki is told to make a contract with the Future Devil.
