Lucifer and the Biscuit Hammer

College student Amamiya Yuuhi leads an utterly mundane life, marked by average grades and a laid-back attitude. His routine is shattered when he awakens to a talking lizard, who reveals a colossal hammer in space threatening to obliterate Earth and enlists him to combat dark forces. Ignoring this bizarre call to action proves impossible, especially with a formidable princess applying pressure to join the fight. Teaming up with her, Yuuhi embarks on an epic quest to gather an eccentric group of allies and confront a wicked mage and his fearsome homunculus before the Biscuit Hammer brings about the planet's doom.
