When Nina is bitten by a wolflike luga and becomes one herself, she is dragged off to the penitentiary academy known as Abigaile, where young luga learn how to serve humans.

As punishment for disrupting class, Nina and Roy find themselves working at the secret parties held by the school’s human instructors. But Nina’s duties quickly become far less more sinister than just waiting tables. The highlight of every party is a fight–wolf vs. luga–and it’s not long before she finds herself thrust into the ring. But that’s not the only trouble Nina’s sticking her nose into. Between picking forbidden roses and standing up for Poe the omega, she’s getting into dangerous territory–and sniffing out terrible truths.

Nina’s perfume has been stolen! Without it, she doesn’t have a way to disguise her true human nature, and there’s nothing lugas hate more than humans. If she can prove she is not like the other humans, Roy promises to give her perfume back–but if she fails, he’ll kill her!

Tsukishiro Nina has just arrived in the beautiful country of Ruberia, and its charming denizens and lush scenery are like a fairy tale come true. Yet suddenly, Nina finds herself set upon by strange attackers until she is rescued by a mysterious young man with a steely gaze, calm disposition - and wolf ears! Whisked away into a grand adventure, Nina must keep her wits about her if she's to learn the secret of Abigaile Castle in a magical world where everyone either makes her blood boil or her young heart race!
