Here is a description of Kansai, via the game’s official website:
Passionate, hot-headed, and acts before he thinks, Kansai loves the idea of strong, brave leaders, and tries to take command of the group.
Even when things go bad due to this carelessness, he has a charm about him that is impossible to hate. He sees Reycho as his arch-rival, causing sparks to fly at times. On his chest, Kansai wears the “Leader’s Badge,” which is only given to a true leader.
As you can tell from his appearance, he loves baseball.
