Kaito Sūnwùkōng
Kaito almost wanted to laugh. These people? Fight demons, ghost, spirits and the like? How? Unless the powers they gained were far more powerful then he thought they would be whatever organization was setting this up would have been far better off just demon-marking a bunch of fighting priest. If everything he had seen was real then he was sure something like that was possible. Why take a bunch of kids with no training? Yeah,one or two others might have combat experienced, but it isn't like any of them...
Wait, why had he been trained? Yeah his mom and dad wanted him to be prepared for the world but... they couldn't know could they? Unless... what if that dream wasn't a dream? That large Monkey spirit had called him 'son' after all... He felt inside again for that pool of energy he had never been able to tap, and once again he felt as if he had slammed into some wall.
Frustrated with his failure again, and irritated at all of the people around him who, after being called lairs for there entire lives, are now doing the same to the one person who said they were right, doubting him; Kaito bounced out of his seat and did a hand stand on his desk. Walking on his hands, he went from desk to desk over to the girl with the brownies across the room. Dropping the pretty girl with the brownies a wink, he grabbed a brownie and said, "Thanks, Your pretty cute." Then he flipped back on his feet in front of the class and casually leaned up against the door, eating the brownie.
While leaning against the door he looked at Saito and simply said "I'm in. Whether or not we actually follow your lead or not is up for debate, but at the very least this should be fun. And for those questioning why, why not?"
