Kanbara Tatsuki

An earnest and sincere boy who was born with a body that doesn't feel any physical pain. Despite the unjust world around him, he wishes to keep on the straight and narrow, even if no one else does.

He began training at a young age under a master who claimed to be invincible in order to become... well, a certain something. He has infiltrated the Benio Family and is biding his time for the chance to free Benio Matsuri, his first love, from their curse.
