The soulless hero: Mercy (Discontinued)

I don't have a plan for what I'm going to do with the story, so basically, Deku has some of the sans au's powers it is a quirk but he is also trained by them because the undertale multiverse collapsed. A few were able to go to a different area being bnha and their powers merged into a quirk it can't be passed on and no one else can do it but because of their powers he is not human he is a hybrid of a human and a monster. He is soulless though, it's his drawback his emotions run off ink and he is not possessed by flowey he just has their powers unlike possession sans. Also is not a full-time reaper he just has reaper sans powers, not the full job.
