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. Ruri seems quite dear to Shun, Yuto and the Resistance according to Reiji. This shows that Ruri had a close and friendly relationship with her brother and the others.

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." Yuto soon afterwards tells Yuzu that she was a lot like Ruri, implying that Ruri was keen in protecting her comrades - Yuto and Shun.
