Well the fat ass deserves to be destroyed dont you think? And who better to sic on him than the girl who got him so terrified earlier on? Sakuya would probably be happy to fuck him up. I mean, she IS a psychopath after all. Granted, a relatively friendly one and one willing to make friends with Asami and the rest.
But as far a sbeing worried about in game characters as one person put it, i dont do that. I am not able to develop such connections with fictional characters. I dont think i will be playing this game again. Ive seen what i wanted to and if i play it again, i will likley be years down the road if and when it is ever finished. I dont see this game being "finished" for a LONG time. prolly a decade or longer/
