I feel like I'm probably the only person who was unmoved by that scene. In Izayoi's case, I just pretend whenever there's some emotional event that she has to participate in, she just fakes feeling sad. The way I envisioned my character isn't one that's falling apart at the seams like everybody else envisions their characters to be doing. Izayoi is just fine with all the death around, and fully expects more dead before the very end. Maybe I'm just griping here, but that's why I feel like emotions shouldn't be tied to the cutscene if the protagonist has to participate. Some people, like me or my character, just don't care one way or the other.
