Always full of energy and cheer, Yusuke is the type who moves before thinking, the complete opposite of the contemplative Kyosuke. His positive attitude and cheerfulness lets him get along well with people.
Yusuke always relies on his intuition, and is a genius in his own right because of it. However, since he fails to notice the smaller details, he often follows his brother's lead instead. He's also not good at studying.

Yusuke is a former professional soccer player and Kyosuke's older twin brother. He was forced to retire after badly injuring his knee attempting to do a risky move during a game.
