now i am totaly lost...that one guy wanted to be reincarnated so i guess that he need body of his descendat? which is MC?No, there is only one MC, the cop you play as, after the intro where you see how Vali died.
Also i wouldn't call him possessed, as Vali has no control over the MC.
and of course that first guy already have some harem of girls wich want him back?
