Personality
He likes to do things while causing as little death and damage as possible. He fell in love with a girl who was cursed to die but refused to cry out for help. He originally claimed to do it for his own reason, but that was only because he didn't want to blame his actions and sins on her.

His eyes are always closed except when in pain or some other strong emotion.

Abilities
His specality seems to be demon excorscing as he mentioned he was able to bind a lower class demon. All his spell use wind and most have demon in their name. He uses an azusayumi cross bow that is used in cemermonial dances by priest and has the ability to fix damaged or distorted minds.

Spells:

 * Fuuma no Gen (Wind Demon's Bow String): Uses the bow to create a ball of wind used to fly.
 * Shouda no Den (Piercing Bullet's Bow String): Uses the bow to create a ball of wind used to blast through objects.
 * Souma no Gen (Seeking Demon's Bow String): Emits a radar to track down a target.
 * Danma no Gen (Severing Demon's Bow String): Uses the bow to fire a high pressure blast of wind.

 * Bon Dori (Lantern Festival): By setting up a barrier that's mixed with Shinto and Buddhism, he can amplify his bow's power to draw out Grimores and read minds. This works both ways so his target can read his mind as well.
