For Tsukishima Miyuu, rebellious prodigal daughter of a world-famous scientist, rules have always been more like suggestions—and suggestions are easy to ignore. But after one too many “creative” stunts, her father finally snaps and pulls the ultimate parental power move: shipping her off to Harmonia University. Or, as Miyuu prefers to call it, maximum-security daycare.

Harmonia isn’t just a school. It’s her last chance. Enrolled in the S.E.E.D. program (Second Chance Education and Development—because why not slap a patronizing acronym on it?), Miyuu must earn XP for good behavior, academic progress, and generally not being a menace. The catch? Fail to hit the benchmarks, and she’ll lose more than her freedom—she’ll lose everything.

Unfortunately for Miyuu, staying out of trouble is easier said than done.
Armed with her sarcastic AI sidekick, K.A.T.O. Miyuu is determined to outsmart the system. She might be stuck in their game, but she’s never been one to play by the rules.
