Yeah I'm sorry but if a demon is telling you “not to get too depressed even if your plan fails” after hearing the plan, IT'S PROBABLY GOING TO FAIL. I can't believe he still went along with it, even despite knowing Lily's opinion on it.
Also, isn't it
incredibly suspicious how Ryouko (the police detective) knew where Misuzu is going to appear? I mean just look at his face, he
knows something is up.
