Kurogane Shizuku's close friend. Nagi likes to give Ikki advice from time to time, and is quite interested in friends' development. Nagi's Device is Darkness Hermit and his Noble Art is Shadow Bind. The device also allows Nagi to use the shadows to create portals that enables travel from one place to another and also immobilize others by pinning their shadows with his knife. Nagi is a male, but identifies as a female and likes to be called Alice. Nagi's true abilities have yet to be displayed, but he qualified for the Seven Star Sword Art Festival, so it can be assumed that he is quite strong.
