Kingo Minamoto

A serious personality who's the son of a samurai. First introduced while on a quest to find his father's killer and take revenge, it turned out his father faked his own death to send him off on the quest to toughen him up a bit as he was originally rather spoiled. After finding out the truth he enrolled into Ninjutsu Academy, making him the newest student in class 1-Ha. His specialty is sword-fighting, which he's studying with Tobe-sensei. Since the trip between his home town and the academy is long, he also stays with Tobe-sensei during school holidays.
