Ruri Kurosaki/Relationship

Shun Kurosaki
Shun Kurosaki is Ruri's older brother who is, like Yūto, protective of her and vows to save her from the enemy.

Yūto
Although there has been no interaction between Yūto and Ruri, it is known that they are good friends. Yūto cares greatly for her and is quite protective, at one point saying to Yuzu Hīragi (whom he had thought was Ruri), "I don't want you to get hurt anymore."
