Where to find Katsuhito / Yosho:
If you go to the Hot Springs you will find him being attacked and if you save him he'll join you.

Analysis:
He's got the highest HP rating, a high Strength rating, and a high Defense rating. He can't move very far, but most of his attacks are lethal and with decent range so it isn't difficult to make up for that. On top of that, strongest attack does the most damage out of every attack in the game.
