Takashi Mitsuya/Relationships

Yuzuha Shiba
Mitsuya must get along with Yuzuha long before, where even Yuzuha seems to feel a little jealous of Mitsuya as an older sister, as Hakkai prefer to have Mitsuya as a wallpaper on her phone instead of her (as Yuzuha, who has Hakkai as the wallpaper on her phone). Throughout the Black Dragon arc, Mitsuya always sought to prioritize Yuzuha's well-being over the abuse of her older brother. Even when making a deal with Taiju Shiba where he would allow Hakkai to go with Black Dragon he only said she would do so with the intention that he would stop mistreating Yuzuha. Later, during the Christmas Conflict, after Hakkai expressed that it was he who her sister protected from Taiju, Mitsuya only had compliments for Yuzuha, where he expressed how much he respected her as her person.
