Description
Detention was supposed to be boring. Nobody said anything about magic.
Miyu Takara is a delinquent with a fiery temper and a sick brother she’d do anything to protect. Sachi Himura is the perfect student council president with a mask that’s slowly cracking. Emi Fuyuki is a transfer student who hasn’t spoken a word in two years, haunted by a guilt she can’t express. They have nothing in common — until a clerical error lands them all in the same Friday detention.
When the detention room dissolves into a starry void and a sarcastic three-tailed cat named Nova informs them they’ve been chosen as the new Starlight Detention Club, their lives change forever. Armed with constellation-based weapons — blazing gauntlets, a crystal bow, and a water whip — they must hunt Echo Beasts: monsters born from the suppressed emotions of their fellow students. But these creatures are only symptoms of a far greater threat. Beneath the school, the Eclipse Phantom — an ancient entity of collective despair — is awakening. And it has already consumed one of the club’s former members.
To seal the Phantom, Miyu, Sachi, and Emi must face their own deepest regrets in magical trials, forge unbreakable bonds, and uncover the tragic truth about the original Starlight Detention Club. Along the way, they’ll discover that the strongest magic isn’t the stars — it’s the friendships they never expected to find.
