Spirit Of a Soul

We have our main character Taroshi,a dude who is a half demon which can control unfriendly spirits and demons,he's parents are missing and his grandparents died by an accident he did,now he lives with his aunt Suzie,who also has a cousin Shiro and a daughter Violet.
However he had to hide the fact he's a demon for not to be killed by the demon hunters,he also met the side character,Misaki who has a brother named Cameo,they didnt get along at first because Misaki found out he was a demon and didn't trust him at first,even tho they'll get along soon.
When they found out he was a demon they were about to kill him but Taroshi explained to them as a result they trusted him,days where getting weird and scary,many spirits where apearing (also demons too-),Taroshi tried to control them and to stop those creatures but it was too much for him,one day he found a cave with Shiro,in this cave there was mytchical spirits,the ones Taroshi can't control and being control by them,which it makes him be full in despair and death.
One day he tried to control one it was getting out of hand as a result,he killed his aunt,he didn't meant to and this is where he got a punishment for killing somebody,the days where getting out of hand,he decided to go to the cave with the mythical spirits,he wanted one more time to control them,but he didn't succed which the mythical spirits took over his control,they were able to do anything to him,so they decided to kill everyone in the villages.
When he was out of his control the hunters were trying to save him but it was too late,Shiro was thinking how to save him,but he knew there was no solution for it,he ended up stabbing him in the heart,there was only the solution to kill the mythical spirit,Taroshi passed out while Miskai was holding him which before he passed out he kissed him (Taroshi kissed Miskai not him-).
No one heard of Taroshi when he died,or mentioned him ever again.
