1) so our already OP MC favourite slime now lives in an academy where many books on magic and all other stuff are huh, i guess rimuru went from OP to calamity in progress OP state....me likes it, and hopefully rimuru will use his ongoing new knwledges for his future fights. id like to see how the demon lords that want to fight him will end up when they do fight him kishishishi.
2) sayings are sayings for a reason huh? i mean the one that goes "clothes makes the man", that last pose rimuru had at the end of the chapter looked real cool and manly even with the girly face he has.
