Head of the Mayuzumi psychic investigation unit, age 14. She is a mysterious young girl who seems to have a lot of life experience despite her age. She has a wide variety of Gothic Lolita dresses. She's particularly fond of chocolate, and won't eat something if it doesn't contain chocolate as well. She only accepts client's cases if she's interested or out of boredom. She is cold hearted and enjoys observing others' misfortune. Mayuzumi's supernatural powers are superior compared to the past generation of Mayuzumi Azakas. Her main ability is to connect with the dead, allowing her in particular to replay the scenes of murder that happened in the past in the place she stand. Her red paper umbrella acts as a medium to support her abilities. It has been stated that each generation of Mayuzumi Azakas is destined to be murdered. One day she found Odagiri half dead lying under a cherry blossom. Out of curiosity she decided to save his life and sealed the oni in his stomach. From that day onwards Odagiri became her sidekick and stays by her side. She is the only person who could seal the oni when it bursts out.
