A boy discovers he can handle magical relics and immediately gets saddled with protecting a dragon girl from people who want to weaponize her. The show treats this premise with genuine stakes instead of winking at the camera about how absurd it is. Ryuji's commitment to Rose isn't romantic posturing, it's the core of why anything in this story matters. The action moves fast enough that you don't have time to overthink the setup. By the finale, you realize the show was never about winning fights; it was about whether Ryuji could actually save someone, or if he'd just become another relic in someone else's collection.
Kisaragi Ryuji lives a quiet life until his cousin Eriko barrels back into town with a dangerous proposition: intercept a mysterious relic before it reaches the wrong hands. What they discover inside the sealed box shatters any hope of normalcy. Rose is a dragon girl, scared and hunted, and the criminal syndicates chasing her will stop at nothing to claim her power. Ryuji finds himself with an unexpected ability to handle relics, making him her only real defense in a world where supernatural artifacts and the people who trade them operate in shadows. As Rose slowly adjusts to her new life hiding in plain sight, a bond forms between them that complicates everything. Ryuji must balance protecting someone he's beginning to care about while learning to wield powers he barely understands, all while dangerous enemies close in from every direction. The action ramps up fast, mixing high school normalcy with escalating supernatural threats that force Ryuji to choose between the safety he once knew and fighting for something that matters.
