Sunadori Satori

Satori is a roommate of Yukito and a classmate and best friend of Chimari.

She is a true pervert. Imagining everything with anything.

She likes very much Yukito calling him her "Prince", but we don't know if it's in a romantic way.

Spoiler

She is very imaginative and fantasizes tremendously about brother / sister incestuous relationships.

Aside from her perversity, she is a sharp-witted girl who manages to reason well in the most stressful situations.
