In episode 6 of That Time I Got Reincarnated as a Slime, Shizue notices that Rimuru is Japanese after he says “I’m not a bad Slime” which is apparently a reference from a game she heard about from a friend she had. We then discover that she got engulfed in flames during an air raid.
Excuse me if I’m wrong, but this seems like an air raid from WW2 and I don’t think there were any games back then. Is she referring to a board game or party game, or have I just got my history mixed up?
I’m curious as to what game she is referring to as well. Where did the idea of living slimes originally come from? Is she referring to a “tabletop RPG”? Where did that quote actually come from?
