Maki Diamond
    Maki Diamond
    The devil who wants Keita's soul. Since, Keita is her first contractor, Maki does not know how to use common tactics, for him to easily give her his wishes (such as seduction or force).

    She is a first level devil and is the princess of Hell. Her power is held by the rings on her fingers, and each can summon one of her guardians when unsealed.
