Tbh I don't really get the hype over this specific anime. I mean yeah, they are being taught to assassinate their teacher, that's kinda fun and exciting right? But I feel like, there is missing something very important. My personal opinion, I think they could have done much better. If I need to be honest, The Graduation time episode was the only sad/good part. Either way, it's you who decides if this anime is good or not.
