Random anime/ mangas: xxxHolic characters

Kimihiro Watanuki is a high school student that sees the un-dead. He doesn't want it but he knows it's a curse he can't get rid of unless he helps them. He wants help and finds a young woman, named Yūko Ichihara, who runs  a shop that deals in granting wishes in exchange for something of equal value to the wish, sometimes it is their souls. To Kimihiros' shock, she is a witch and will help him, in exchange for him working for her to pay off her services. His job is nothing he ever expected it to be. That's for sure.

Yūko helps and fights beside Kimihiro to regain peace to the planet and soon becomes great friends with him. Then she is to leave sooner than they both expected. Kimihiro doesn't want her to go but knows it's for the best.
