Sisseli - A fun, unique and loving girl who's very pretty but doesn't know it. She may often be jealous of those close to her, but she's always there when you need her. Sisseli has a very caring nature, and does not give up on her closest friends. You don't want to mess with her or her friends, because even if she's really sweet, she's also really sour.
