Kakeru can't win at the thing he loves most, so when a creature gives him actual power, he doesn't hesitate. The card game stops being a hobby and becomes real stakes. By the time he realizes what he's protecting, he's already too deep to walk away.
Kakeru lives and breathes the Live On card game, spending his allowance on booster packs and practicing relentlessly. Problem is, he can't win a single match. His deck strategies crumble, his timing is always off, and his confidence keeps taking hits alongside his losing streak. Everything shifts the moment he stumbles upon a small creature being hunted by shadowy figures through the streets. The animal isn't what it seems. When Kakeru protects it, the creature reveals itself as a Create Monster and grants him a card that defies all the rules he knows: a Live Change card with impossible power. Suddenly Kakeru has a real reason to fight. His practice matches become something far more serious as forces he doesn't understand begin circling him and his new companion. The game that once felt like a casual hobby becomes his gateway into a larger conflict, one where his newfound monster friend depends on him to learn what he's truly capable of.
