Reviewing the first omnibus volume for Anime News Network, Rebecca Silverman commented that the story "takes a while to hit its stride, but when it does, putting it down becomes difficult", writing that "underneath the goofy start and typically comedic devices of absurdly powerful girls and talking animals, Lucifer and the Biscuit Hammer is hiding a very dark story" which makes it "feel very different from most of the other series currently available in English." She gave it an overall grade of B. Silverman would later list the series as the runner-up for the "Best Reworking of an Old Genre" spot on her 2015 manga retrospective article for Anime News Network. Charlie Jane Anders of io9 placed the series at number ten on her list of "10 Heroic Prophecies That Didn't Turn Out The Way the Heroes Expected".
