Toko has learned to love Genocider over the years and not blame herself for letting Syo live. I mean, the only reason she has DID is because she's had to go through so much trauma. Syo was just trying to help her. By the way, Genocider doesn't really kill anymore these days. She actually has quite a sweet barbershop on the other side of town! Needless to say, Toko and her are much more happy and lively these days.
