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.

Despite her lack of trust, she seemed somewhat grateful to him for helping Blake when she ran away, although she says that she's "still not quite sure" how she feels about him.

In the Academy library he refers to Weiss as "Ice Queen" implying he holds a negative view of her personality.

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 after she fled from her teammates, and they quickly formed a friendship. Although his petty law-breaking seems to annoy Blake, she earlier sprung to his defense him when Weiss was speaking ill of Sun.

At the same time, Blake's quiet and reserved demeanor causes Sun to tease her a little. Even though they've just met, Sun seems to be somewhat protective of her, shown when he jumped in to help her during her fight with Roman Torchwick. Both seemed to work together well during the following fight.

Ruby Rose
Although interactions between the two have been few, Sun seems to get along well with Ruby.

Yang Xiao Long
Despite only shown having few interactions, Sun also seems to get along well with Yang as well.
