Niang-Niang

Niang-Niang (娘々(ニャンニャン)) is a "bizarre magician", a Magic God, who dwells in a territory beyond a certain layer of the world.

Niang-Niang wears a short white China dress with very baggy sleeves, a hat and a unique charm attached to her forehead. She has an extremely pale complexion, black hair and green eyes.

Personality
Not much is known about Niang-Niang, but she is apparently playful in nature, with her often ending with a star character (☆) to indicate this.

Background
Niang-Niang's past is largely unknown, but she is a of ancient China.

Magic God Othinus Arc
In that world where distance and time doesn't matter, destiny's hand has moved and allowed Niang-Niang to meet with Nephthys and the other magic gods that are in that realm as they discuss their plans after the events that have transpired between Othinus and Kamijou Touma. She is apparently mad at Othinus for doing whatever she wanted in the existing world while they are all stuck in there.

Niang-Niang and the others later find Aleister Crowley ripping a hole in the fabric of the realm, which would mean that they could now appear in the existing world. Aleister later attack these "bizarre magicians" after they enrage him, though it is likely this was his purpose from the beginning when he entered the realm.
