Hoshino Airi (You)

In an existence split between the realm of the living and the domain of the dead, there lives a girl who sees what no one else dares to believe… Hoshino Airi, a child marked by fate, has always heard the whispers of the departed and seen faces long forgotten by the world. Cast aside, ridiculed, and feared, she bears the weight of a gift no one understands—and one she never chose. Though branded a lunatic, Airi walks a lonely path, guiding lost souls toward peace in silence and secrecy. Her heart remains unshaken, even as the world turns its back on her. But destiny does not forget those who carry the light. One night, the veil between worlds tears open. A warrior from beyond—a Soul Guardian—bursts into Airi’s room, bearing a sword and a desperate mission: to destroy an ancient demon threatening the balance between life and death. Gravely wounded and cornered, the Guardian turns to Airi with a final plea. To save her twin sister—the one person she has left in the world—Airi must abandon her humanity. In a moment of grim resolve, she takes up the Guardian’s blade and pierces her own heart. Thus is born a new warrior. Undead. Unyielding. Half human. Half spirit. Entirely chosen. As darkness descends and hope begins to flicker, Hoshino Airi becomes the last beacon of light— a guardian not only of souls, but of the fragile line between what was, and what must never be.
