Seiichirō Kitano

Seiichirō Kitano is the main hero and a boy whose face inspires terror and despair in other people's hearts, but whose true nature is that of a kind-hearted boy. His gentle and caring actions mostly frighten those around him, and while he's used to getting hit for no apparent reason at all (except for his terrifying features), he has a natural ability to move instantly along the direction of the hits thereby suffering little to no damage. He is also observed of having the will to remain standing despite injuries (whether cosmetic or real).

Although he has no martial arts skill at all and doesn't like violence, he would often jump into fights head on, either to protect someone or to break the fight. Of course, coming headlong into fights while screaming incoherently (a trait that was also seen in Kitano's father that happens when both are in a state of panic), 'armed' with his already-mentioned scary countenance only serve to confuse the ones he face, and more importantly to serve the rumors of him being a delinquent, especially when the usual circumstances made that he is the only remaining person standing. Because of all the fights he gets caught up in, Kitano's speed and reflexes advance to a near inhuman level, his reflexes are at the level where they can keep up with a martial arts master while his speed is great enough that using he becomes a blur and simultaneously avoid three martial artists.

At the beginning of the series when he got into a fight he would stand around getting hit by his opponents avoiding the brunt of the damage using his previously mentioned counter then ending the fight with his trademark double-palmed push. As the series progresses however his fighting style switches from constantly getting hit to then avoiding hits with inhuman speed.

Aside from his speed, reflex, and his stubborn will, Kitano also occasionally uses a special finishing move, a double-palmed push. It is, literally, just a push. Fortunately, or unfortunately, it also bears behind it the whole of Kitano Seiichiro's will. It has been observed repeatedly of having the capability of lifting the victims off their feet and sending them soaring several feet away. This finishing move is instinctual, and mostly used when Kitano is trying to protect someone.

Characteristically of the series, the angel-hearted Kitano would misunderstand the actions of the people he faces (or forced to face), never even thinking ill of them, while the reverse is almost certainly true. This is the running gag that serves as the centre of which the story revolve around. An amusing fact was revealed in chapter 40, that apparently Kitano and his father can apparently communicate with perfect understanding when both are doing the incoherant screeching that has become one of Kitano's trademarks.
