When she was a newborn baby, Yuushi was found by a victorious warrior following a shining light on the battlefield. He raised her for seventeen years. Unfortunately, her body stopped growing seven years too early and she looks like a ten-year-old. That’s not all bad, though, because she is luckily chosen to be one of the candidates for Platinum Princess, who wears a magical tiara capable of granting any wish.
But wait! There are plenty of other candidates going to school with her—including Grenda, Yuushi’s arc-rival and princess of Hell who also seems to have fallen into a body too young for her soul—so she must work extra-hard to win her spot.
