Jukai (寿海, Jukai) is a doctor who heals the sick and makes prostheses for the unfortunate. He is also Hyakkimaru's parental guardian.
He once served for Lord Shiba, however, he is currently redeeming himself by offering treatments for free, hoping to erase his guilt.
Appearance
Jukai is a middle-aged man with a beard and a stout body. Despite being a doctor, he wears very shabby and tattered clothes, probably because he does not charge his patient much, in anything at all, for his prostheses.
Personality
In the past, he was once relentless at torturing and crucifying persons by order of his former Lord. However, it's lately discovered he didn't enjoy of these acts at all, coming to a point he snapped and tried to commit suicide which is a proof of his self humanity.
After that event, he's shown with a kind and selfless personality, where he took care and helped others without any reward. However, he's highly dedicated and workaholic at the point of not resting just to give prostheses to unfortunate or corpses.
He's always with an unhappy look as he always holds the guilt of the atrocities he did in the past and often asking himself why he didn't die when he threw himself off the cliff.
After his former foster son Kaname realised he crucified and tortured his parents, he's conscious that the death would be his fate for all his faults.
When he met Hyakkimaru as a newborn, he's shown to develop a close bond with him like he used to with his former foster son. That bond was however more pure as he made a whole body for him, raised and trained him in combat.
