Mana Takamiya

One of the Wizards of DEM (Deus Ex Machina), an organization which provides realizer units to other wizards throughout the world to fend off spirits. When DEM was transferred to Tenguu City's AST, she was posted on that spot to deal with the Spirit called Nightmare. Mana doesn't recall much of her past and it is said that she's one of the best wizards existing.
