シキシマ

The elusive my-pace artist. He is neither a delinquent nor a good student. Everyone recognizes this person as an eccentric man and, just like that nickname, his movements are also considerably strange. He appears and disappears everywhere around school, always alone and quietly drawing. [From Otome Jikan] His full name is Shikishima Natsuhisa (四季島 夏久). He dies at the age of seventeen.
