It all started in Other World, or to be more specific it started in Hell. A lone woman in a purple cloak can be seen running down the hallways of a castle. As she ran, the castle was rocked with explosions. The tremors which were created by the explosions, caused the woman to stumble. Once the woman stops stumbling, she starts to run again. The woman keeps running until she reached a red door with a black rose pattern. When the woman opens the door, a young girl ran out of the door and into the woman's arms. The girl was wearing a gown and she had a tiara in her hair. The girl had demon wings which grow out of her back; a much smaller pair grew out of her head along with a pair of horns. And lastly a tail that ends with a heart like arrow head came out of a hole on the girl's gown.
The woman picks up the girl and starts to run again. She continues to run until she reached a flight of stairs. The woman went down the stairs and enters a room with an altar. The woman set the girl on the altar. The girl looked at the woman and said, "What's going on mommy? Who's attacking our home?" The woman looked at the girl and said, "There is no time to explain Mitsuki. I am sending you to the world of the living so that you will be safe. We will meet again some day."
Mitsuki's mother then gave her daughter a long hug and then she took a few steps back. She then chanted in demon tongue. After she finished her chant, Mitsuki disappeared in a very bright light. With her daughter gone, Mitsuki's mother turned around and walked up the stairs. Once she reached the top of the stars, all she could see is a world of fire.
Meanwhile in the world of the living, the crane hermit, Master Shen was training his two students, Tien who was age ten and Chaozu who was age six. In the middle of their training a bright light appeared. When light subsided, Mitsuki appeared. Mitsuki walked over to Tien and mumbled, "My mommy…" After she finished mumbling, Mitsuki passed out and Tien managed to catch her in his arms.
