Ruri Kurosaki/Relationship

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

Yuto
There have been no interaction between Yuto and Ruri, although it is known that they are good friends. Yuto greatly cares and is quite protective of Ruri - at one point saying to Yuzu (who he thought was Ruri) "I don't want you to get hurt anymore."
