Dai Yuuzuki

Background
Dai is the cool type so he's the brains of the team and sometimes think that Satoshi's idea's are stupid. He's great at sword fighting so he basically shuts people out until Iris helped him out of his shell and became less cold. Dai is serious all the time and always do experiments on pieces they get from the battle. He gets annoyed whenever Satoshi wants to spend time with Karen because Satoshi babbles a lot.
