Hsi Wu

Hsi Wu was the Demon Sorcerer of Sky who hailed from a family consisting of himself as well as seven siblings and later on his nephew Drago.

Appearance
Since he's the Sky Dragon, he appears to be a human-sized black-skinned demon with wings.

History
He was one of the last Demons to be released, his portal located outside the women's room in Fenway Park. Jade accidentally snapped off his tail, forcing him to flee. He tried to retrieve his tail but Uncle placed a spell that would prevent demons from entering the shop unless they were invited. Seeing Jade, Hsi Wu saw his opportunity. He disguised himself as a human boy named Seymour Jahoositz and quickly befriends Jade. He gets inside the shop and nearly to his tail only to be pushed out by Uncle. Next day, he was invited to the Spring dance by Jade and gave him a necklace with one half a coin. He once again tries to get into the shop only to find that Uncle had hexed his tail to immobilize him. Hsi Wu catches his tail in a bag, revealing himself to everyone (including to the horror of Jade). He kidnaps uncle, demanding that he undo the spell; Uncle said that he cannot and required to do another spell, but needed books. The Dark Hand brought spell books but their efforts were hampered by Jackie and Tohru. Hsi Wu flew off with his tail, determined to find some other way. But Jade, empowered by the Rabbit and Rooster Talismans, begins a flight chase across the industrial district. She is able to release his tail on him, as Jackie played the flute, sending him back to the Netherworld.
