Kimihiro Watanuki is not your typical highschooler. He can see spirits and they were inevitably attracted to him. One day, while trying to free himself from the grip of some spirits, he accidentally smacked a wooden fence. Instantly the spirits vanished but Watanuki had a new problem. Against his will, his feet started to move on their own towards the house and before he knew it he was ushered to meet the master by two little girls.
The master of the house was a witch knowned as Yuuko. She told him that their meeting was pre-ordained and read to him his current situation. As a price, she cheats him of his pocket watch whilst telling him about her wish-granting business. While he tried futilely to argue, she offered to make his secret wish come true - to get rid of his ability to see spirits. In return, he only needed to work for her until she felt that it was enough to pay off the wish (hey lady, that's too subjective!).
Watanuki was swept away by the situation and found himself doing groceries shopping with a weird black creature named Mokona. At the supermarket, a spirit latches itself unto him. Irritated, he contemplates the decision to let Yuuko take away his special ability to see spirits. On the way back to Yuuko's shop, he came across a girl who was complaining to her friends about some spirits following her. I think she's a liar and that she was only trying to seek more attention. Hmph!
Being able to see spirits himself, it was clear to him that the girl was lying and tells her that there was no spirit latched onto her. She became angry at his intervention and made a big drama to save her face. The girl bumped into him as she stormed off with her friends and suddenly the spirit who was curled around Watanuki went to her and swallowed her whole, latching itself permanently.
Angrily, Watanuki confronted Yuuko for not telling him that he was able to transfer spirits by touching other people. Yuuko however dismissed his accusation and simply told him that the spirit was granting the girl's wish to be possessed. Not accepting her answer, Watanuki decides to quit and left the shop. As he leaves, Yuuko commented that a bond has formed between them and he would surely return. True enough, the next day he found himself in front of her shop again, trying to kid himself that he was only there to make her pay him back for the groceries money.
Another great work from the famous group CLAMP. Great music, great artwork, and great start of a storyline. What can I say, I'm a huge fan of CLAMP. :D
