Irises bloom, and fate turns.
On a stormy night, the boy Lin Yan awakens a contract with an iris that has slept for a thousand years while trying to protect a strange child.
Petals become blades, and faint light becomes a shield. As he fights shadows again and again, his body undergoes a slow, irreversible transformation, step by step becoming more like a girl.
Far away in the shadows, the other magical girls, who have long borne flower contracts of their own, gaze toward him from afar, following the ripples of his soul. Filled with pity and passionate affection for this pure iris soul, they secretly develop a possessive fixation, never realizing that the iris contract-bearer they care for is, in fact, a boy.
Beneath the brilliant irises lies the heavy price carved into the contract. Every time he casts a spell, it wears away at the male self he once was. Alone in the dark, he stands against shadows that devour cities, while struggling to pass as an ordinary boy in everyday life and fearing the gradual transformation of both his body and his heart. When his secret is finally exposed, and his admirers glimpse a truth that overturns everything they imagined, what awaits him is a storm, a struggle, and a long search for where he truly belongs.
