Kirio Yamada
山田桐生
[Aoi's](https://anilist.co/character/32292/Yamada-Aoi) older brother who has been constantly searching for her. Like Aoi, his surname is an alias which coincidentally matches hers. He is the captain of the karate club and is strong enough to defend himself against [Mahiru](https://anilist.co/character/24419/Inami-Mahiru), who he gains a crush on.
