Can a heart be programmed—or does love rewrite everything?
In a near-future world where humanoid computers called persocoms blend seamlessly into everyday life, college student Hideki stumbles upon an abandoned, mysterious persocom he names Chi. As Chi learns about the world with innocent curiosity, Hideki is pulled into a deeper mystery about her origins—one that challenges what it means to love, to be human, and to choose your own path. This anniversary edition celebrates CLAMP’s classic blend of charm, humor, romance, and thoughtful sci-fi questions.
