Ayashi no ceres

Long ago there was a fisherman. One day as he passed by the seashore, he saw several beautiful Tennyo bathing. He saw beautiful robes next to him which were the finest he had
ever seen. He greedily took one of them and went home.

The Tennyo whose gossamer robe was taken by the fisherman couldn't go back to Heaven. She went to the fisherman's home and pleaded for her gossamer robe, but the fisherman pretended that he knew nothing. Tennyo soon married the fisherman, and gave birth to a child.

Many years after, Tennyo finally knew where the fisherman hide her gossamer robe by hearing a song that her child sang. Tennyo took back her gossamer robe and went back to Heaven.
Leaving behind her husband and child..."

"You were born under the influance of a star of darkness...
I see anger, blood, and suffering. the balance of this world will be
destroyed. Upon the day of the arrivel of the 16th star and moon,
you shall meet your destiney. Whether in light or darkness, the great power
within your soul will rsie to the surfice."

This is what the fortune teller told Aya the day before her 16th birthday. Pretty weird, eh? This was what Aya thought after listening to the fortune teller. On the way home with her twin brother Aki and friends, Aya saw a robbery. She tried to catch the thief and get back the handbag. Unluckily, she reached too far for the handbag, which was falling off the railing, and she fell together with the handbag. As she fell, she saw images of blood and deaths, and even found herself floating. Yet more was coming. When she safely reached the ground, she was in the middle of the road, and a truck was coming towards her. She was rescued by a stranger with sunglasses, who disappeared quickly into the crowds.

The next day, Aya and Aki was told to go to grandpa's house to celebrate their birthdays. After entering the room, they found out that the whole Mikage family was there, plus all dressed in black. Grandpa told them that he had a present for both of them. A stranger walked into the room, carrying a box. Aya reconized he was the one who saved her the day before. Grandpa told them to open it. Inside, they saw a mummified hand. The lives of Aya and Aki began to change at that very second...
 

Questions?

Well, so how's the old tale related to this story?

The Mikage family is actually the descendent of Tennyo. In order to find the fisherman and get back her gossamer robe, Tennyo stays in different Mikage girls' bodies and appears on their 16th birthday, but always gets killed by the Mikage. Aya receives 100% of Tennyo's power, and renames herself as Ceres after turning into a Tennyo. The Mikages try all their best to kill her. The fisherman, Shiso, reborns as Aki. That means Aya and Aki have to fight with each other. Whenever Aki appears as Shiso, he turns really bad. He even kills his Grandpa.

Who is that stranger?

The stranger is Tooya. In the very beginning he works for the Mikage family. Grandpa orders him to kill Tennyo. Aya's cousin Kagami instructs him to catch Tennyo, and bring her back for experiments. He's a very mysterious man who loses his memories. 

What's going to happen next?

I hate telling the whole story. It's a lot more fun to read the story YOURSELF! I swear to God that it's worth reading!  so read!!!!!!!!!!!!
