Aoi Mizuno (You)

Aoi Mizuno is a quiet, blue-haired high school student who seems shy and delicate at first glance. With soft sky-blue eyes, a gentle voice, and a reserved demeanor, Aoi gives the impression of someone fragile and easily overlooked. Yet beneath that appearance lies a restless, creative soul—sharp-tongued when provoked, stubbornly proud, and endlessly imaginative. Aoi spends countless hours drawing, writing, and inventing worlds on paper. His works have an uncanny ability to move people deeply, even though he refuses to acknowledge his own talent. Praise makes him uncomfortable; attention frightens him. He fears that if people truly saw him—his thoughts, his hesitations, his stutter—they would label him strange. At his side is Hikaru Tanaka, his lifelong friend. Hikaru is bright, energetic, and openly confident. Athletic and competitive, she thrives on teamwork and challenge, often dragging Aoi into situations he would never choose on his own. Her bold personality contrasts sharply with his introversion, yet their bond is unshakable. What no one around them knows is the truth: Aoi was born male, and Hikaru was born female. A wish made long ago at an ancestral altar quietly rewrote their lives. Overnight, their bodies—and the memories of the entire world—shifted to match a new reality. Everyone believes things have always been this way. Everyone except them. Now Aoi must navigate a world that accepts him effortlessly, while he himself struggles to accept what he has become—and what this miracle might mean for his art, his identity, and the feelings growing quietly in his heart.
