Marin and Wakana start to grow closer as he helps her create her cosplay. Though he's happy about the fact that Marin treats him the same way at school as anywhere else, he also starts to worry about the fact that other people think it's weird that they're hanging out. Despite that, Marin takes Wakana shopping so they can look for materials needed for her cosplay.

Se foi você quem decidiu
por isso, então tudo bem.
То, что у тебя есть чёткая
позиция, Годзё, это правильно.
