That was fucked up but I like it

Wait I’m so confused what happened at the end?

Actually miwako wanted to be killed. Because she is an immortal, only original's familiars with their arm can end their life. Thats the reason why she provoked him into despair so he will kill her. but in the end hirota osamu realized it and didnt kill her to take the real revenge. If he were to kill her, it would be what she wanted
