Plot
Yuuhi Amamiya is a young, misanthropic college student who one day wakes up to find a lizard on his bed. The lizard explains that Yuuhi has been chosen as a Beast Knight, a magical warrior destined to help a princess defeat a mage seeking to destroy the world with a giant mallet floating in space called the Biscuit Hammer. While Yuuhi initially is not interested in getting involved, he changes his mind when he meets the princess, Samidare Asahina, who tells him her intent to defeat the mage and save the world so she can destroy it herself.

Manga
In 2011, the series was nominated for the 42nd Seiun Awards in the comics category.

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".

By 2022, the manga had sold 650,000 physical copies.
