Lucifer and the Biscuit Hammer

Yuuhi Amamiya, a college student, lives a mundane life until he meets Sir Noi Crezant, a talking lizard claiming to be a knight of justice. Crezant warns that the world is threatened by Animus, a mage who plans to destroy it with the Biscuit Hammer, a massive structure orbiting Earth. As the self-appointed Lizard Knight, Yuuhi is supposed to fight alongside other Beast Knights to protect the princess and save the planet. However, his neighbor Princess Samidare Asahina has a different goal - she wants to destroy the world, and Yuuhi finds himself drawn to her determination.
