Gwess

グェス

Jolyne Cujoh's cellmate in Part VI: Stone Ocean. She is introduced as a minor antagonist, but remains neutral with friendly tendencies after Jolyne defeats her.
Gwess initially gives the impression of being sweet and kind. Originally, she was seen with a "pet" that she made talk and gave treats to. If it refused, her personality quickly shifted into that of a mad-driven woman capable of killing for fun. She also has no problem with tricking others, yet is nevertheless a coward. Unaware of the nature of stands, she didn't participate in any battles following her conflict with Jolyne and resigned herself to reading magazines and otherwise acting subservient toward her roommate. When Jolyne was under the effect of Miu Miu's Jail House Rock, Guess hardly talked and was very timid.
