Rimuru Tempest is the main protagonist of That Time I Got Reincarnated as a Slime and has appeared as the reincarnation of Satoru Mikami. She is an eccentric and childish individual, as we can notice in our fanart Tensei Shitara Slime Datta Ken Rimuru Crying Sticker. Underneath that, Rimuru is constantly analyzing, planning, and weighing the pros and cons of his actions, taking the smart move in the long term over more rash and emotional decisions.
