In a kingdom where everyone Awakens with a heroic power on their sixteenth birthday, sleepy little Yua awakens with the worst stat ever printed: '1 HP.' One hit and she's done — RANK F, POWER: USELESS, and the whole stadium laughs. Except the System never read its own fine print: her HP can't drop below 1. Ever. She doesn't get stronger; she just can't lose. So she deadpan-walks through dragon-tier attacks, finishes her juice box, and pokes the boss until it falls over — while the chipper game System slowly loses its mind and something ancient opens one eye to ask why she can't remember why she can't die.
