Dark Lord

Mao is a supporting character in The Great Jahy Will Not Be Defeated!. She is the No. 1 of the Dark Realm, and Jahy's sole superior.

Appearance
In her new resurrected form, Mao appears as a young girl with long black and red hair, much smaller than her original form. She has two horns on the top of her head and red eyes. She wears a dress that reveals her shoulders.

Personality
In order to regain her strength, Mao is a glutton that would eat any food in front of her. Even so, she was okay giving a tiny bit of food to Jahy. She is quite indifferent to anything else except eating and sleeping, and doesn't even talk. Mao prefers staying with the magical girl, because of her food supplies.

It is implied later in the series that Mao was so spoiled by the people of the dark realm (especially Jahy) that her current personality is not far off from her previous personality. It is unknown how much of it she ordered Jahy to do or how much Jahy did on her own.

Abilities
Being not only the lord of the Dark Realm but also part of the Mana Crystals, Mao possesses a magical ability far exceeding that of any other entity within the Dark Realm. It is safe to assume that without her no demons would be able to use magical abilities.
 * Mana Crystal Manifestation: As the Mana Crystals are an aspect of Mao she is able to manifest when enough crystals are in one place. This however does not bind her to a location as she can move about freely once manifested.
 * Super Speed: Mao demonstrates an amazing level of speed despite her slothful demeanor. She is not only capable of consuming all food on a table in a matter of seconds but can even swipe food from a greater distance without anyone seeing her move.
 * Shape Shifting: Mao demonstrates multiple times the ability to alter her physical form, able to turn into a cloud like form to move both quickly and freely. She also is able to fit herself into Kyoko's school bag without Kyoko noticing until opening it.

Trivia

 * Mao's name literally translates to "demon king". It may be more of a title than a given name.
