Kaname Yamashiro

A free-spirited gyaru. She's hard to get a read on because of her elusive nature, but her speech and actions often strike at the essence of people's issues. Her parents work overseas, so she lives alone in the penthouse of a high-rise apartment building.

Note from the author: A while ago I bought a book about psychopaths for future reference and it had a lot of things to say about Kaname-chan.
