Rain

ay..how to write this n make sense--

Childhood friend with Oni and Aim. Stopped being in contact once Rain ran away.

Born of a human female and a powerful snake beast. He denies any link with his 'beast' blood part and so, when he got the chance, he ran away and choose to become a demon slayer instead;He purifies and exorcises demons with his sword and blood. He grew up in his father's lair up to age 13,then got haven at a parish in the nearest town. Working at different places, learned how to battle and sword fight.Him supressing the urges of his demon self, created a second personality, that happens to pop out every once in a while when stressed.

Half his power and effectiveness against demons resides on the fact that he is, in fact, virgin. ( _(´ `;;)/(_)_ finding logic here it's dumb, don't even tr y..)

Oh yeah.. one of his half-brothers its in his search to murder him and take the place to succeed his father.
