Collapse: Shaking Up the Card World

When an alien spaceship crashes onto Blue Star, it doesn't bring invasion—it brings cards. Thousands of years later, Yuan Yu finds himself in this card-powered world with a glitchy system and one simple goal: quietly explore pre-Honkai civilization tech. But nothing stays quiet when pink-haired girls quote philosophy while remaking reality, and 'cute hearts' become omnipotent weapons. What starts as harmless tinkering spirals into chaos as Yuan Yu's experiments unleash powers that were never meant to see daylight. In a world where cards define everything, he's about to rewrite the rules.
