Esaka brings Kotarou to a new training facility, likewise presided over by Guardian, where Kotarou begins training as a soldier. Things do not go well as he is bullied by the other superhumans there, believing his powers to be inferior to theirs. However, Kotarou still makes a new friend, the jolly, good-natured Luis. They have fun and spend time together during breaks or play with the poor children living in the neighbourhood, one of whom is Midou, who proves to be a mischievous, playful young boy. The two men also befriend and help the young but mature Yasmin look after them occasionally. In this fashion the days pass, but Kotarou feels he is still living in a standstill. Everything then changes when the soldiers are sent to raid a factory, only for Kotarou and Luis to find an immense monster they cannot defeat. Thinking fast, they search for the summoner but find the band of children instead, hiding in an attic. Luis is overcome with grief and shock when he accidentally shoots the children upon coming across them, and proceeds to rescue Yasmin, Midou and two other boys. In the process, Luis gives up his life to save the children, at the same time giving Kotarou the motivation to let his fears go and move on.
Returning to Guardian's main headquarters, Kotarou reports everything to the commanders while covering up the children. Secretly, he also rents a home for the children to be kept safe, bringing back other children used as summoners and stray superhumans. These children were the result of Kotarou's pity for them as they were used by Gaia due to their poverty. In the end, Kotarou's missions in Kazamatsuri are complete and he bades goodbye to Yasmin and the children.
