Can someone explain to me im confused about jin

He’s basically the bad guy that Chiwoo is fighting against. That’s why Jin didn’t get his memory erased like every other person because he’s just like Chiwoo with his own little alien thing like sunny but he’s just a bad one

I thought he was the other magical weird sex fighter that the chibi fluff ball was talking about ;-;

Yea, he is

oh then how is he the bad guy??
