Nadat een 37-jarige man door een overvaller was vermoord, bevond hij zich in een andere wereld als slijm met unieke vaardigheden. Met zijn nieuwe naam, Rimuru Tempest, die hij kreeg nadat hij zijn nieuwe vriend had ontmoet, de stormdraak Verudora op 'rampniveau', begint hij zijn nieuwe leven in een andere wereld en met een toenemend aantal volgelingen.
