Seiichirou Kitano
The main protagonist, 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 he's used to getting hit for no apparent reason at all, so he developed speed and reflexes which allow him to absorb the power of the blows; although he has no martial arts skill and doesn't like violence, this in itself is enough to make any skilled fighter lose their will to fight, so he's technically unbeaten.
