Sun Wukong/Affiliation

Weiss Schnee
Although unaware of it, Sun Wukong is seen as "riff-raff" by Weiss, who has prejudices against Faunus due to her family's history with them.

Blake Belladonna
Sun Wukong seemed to develop an attraction to Blake when he first saw her. In addition, he suspected Blake was hiding something under her bow. Sun was the one who comforted Blake, and they quickly formed a friendship.
