She normally keeps her thoughts to herself and accepts most situations with no protest, though she voices her dislike of boring situations. Unlike Kouhei Katsuragi, who has a conservative stance, Arisu possesses an innovative attitude. The two each lead separate factions within Class A, though the majority of the class submit to Arisu.

[Spoiler: She was mentioned to know Kiyotaka Ayanokouji and his past in the novel. This makes her the first person to know about Ayanokouji's mysterious past.]
