In the city of Tsukimori, where nearly everyone possesses hidden powers, 17-year-old Yukio Naruzawa stands out-but not in the way she wants. Unlike her family and peers, Yukio's powers have yet to manifest. However, what she lacks in ability, she makes up for in her secret life as the vice-captain of Kurohana, a gang resisting control from the powerful Hikari Organization.
As tensions rise between the gangs of Tsukimori, Yukio juggles her double life, keeping her best friends, Suzume and Kazu, in the dark to protect them. But things take a dangerous turn when Hikari's enigmatic leader, Hido, sets his sights on Yukio, believing she holds the key to his plans for domination.
Caught in a web of secrets, betrayals, and hidden powers, Yukio must navigate her role in Kurohana, protect her loved ones, and uncover the truth about herself-before it's too late.
