Sala de Aula dos Heróis

It started with potential for a fun but stilly anime, but quickly degraded with regurtitated stereotypes such treating everyone as a potential friend despite clear murderous intent. It doesn't matter if it's a robot or an army of clones, it doesn't matter if they have no intention of doing anything but getting strong enough to murder the main character, nor does the fact that they've already made multiple murder attempts already, everyone is really a nice person and just wants to be their friend. Other notable problems are the harem-nature of the show and the fact that there's a limit to how stupid you can believe the main character to be.

It was a somewhat enjoyable watch, but I've no interest in seeing anymore.
