Despite his unease Hajime takes to parenting Myu quite well. They return to the city where Hajime and the other heroes were summoned. While visiting the Adventurers Guild Hajime meets a panicked Endou, one of his classmates, who warns them Cattleya the Demon set a trap in the labyrinth for the rest of the class. The class are overwhelmed by Cattleya's summoned monsters, unable to even get close to Cattleya to try killing her. Hajime is indifferent until Endou upsets Myu and he becomes downright reluctant to help at all. A student, Suzu, is injured, causing most of the class to flee. Hiyama suggests signing contracts with the demon to survive. Kouki, the main Hero, gets close to Cattleya, but hesitates after she drops a locket with a picture of her lover, realising she has a life outside the war as well. While hesitating he is seriously injured. With support from the girls Hajime decides to save his class, reasoning only one of them tried to kill him, meaning most of them are innocent. Shizuku's sword is broken so she prepares to die alongside Kaori. However, they are saved at the last second by Hajime, having created a shortcut using his Pile Bunker to blast through the upper floors. Everyone is shocked to learn Hajime is still alive.
