The animation is a disaster for stretches, CG that looks like it crawled out of 2008. Ignore that completely, because what lives underneath is a story about two people who want to destroy everything building something worth saving instead. Samidare isn't your villain who learns to be good, she's chasing her own apocalypse while Yuuhi learns that his powerlessness was never the point. The show breaks its own genre rules to ask what it actually costs to care about someone when you're designed to be enemies, and by the end you're not watching an action series anymore, you're watching two people choose each other over the world.

Yuuhi Amamiya's ordinary college life shatters the moment a talking lizard shows up asking him to save the world. Before he can refuse, he is made one of the Beast Knights, given a ring that grants a psychic power called domain control, and thrown straight into combat. Just when defeat seems certain, his neighbor Samidare steps in to rescue him. She is a princess of absurd strength, and she has no interest in protecting Earth. She wants to destroy the planet with her own hands. Drawn to her ambition, Yuuhi becomes her devoted servant and trains to grow stronger so he can help her reach that goal. As the pair keep fighting the golems sent by the mage Animus, who means to crush the planet with an enormous hammer hanging in orbit, Yuuhi slowly starts to care about living, though his past trauma still holds him back. The mix of comedy, action and psychological drama gives the supernatural premise a darker edge.
