Manga/Graphic Novels Starting With 'X'

Kimihiro is having some wish-granting success with his very first customer, but his efforts are interrupted by a disturbing dream of the witch Yuko vanishing forever. Even people Yuko has helped are saying they've never heard of her. Too bad there is no such thing as "just a dream" in Kimihiro's universe...

The witch Yuko is gone, vanished and forgotten by the world with the exception of a small handful of people. But Kimihiro is determined to keep the wish-granting shop going, even if the shop's arcane rules nearly kill him for the crime of setting a wrong price. Now begins a new chapter: xxxHOLiC Ro!

Watanuki's vow to the witch Yuko, who has disappeared, leaves him in charge of the shop where wishes must be granted to those who meet the price. Enter a deranged customer who is determined to capture the heart of the man she is stalking. Now Watanuki may have no choice but to deliver his friend Shizuka Domeki into the arms of this unstable woman!

Yuko gives a young woman a precious cylindrical box from her treasure room. There's just one caveat: she must never open it. Inside is a magical device with a terrifying reputation! Can Kimihiro save an ambitious young lady from her own overconfidence?

Yuuko's latest customer is a rain spirit who wants Kimihiro dispatched on a rescue mission. Little does Kimihiro know that this mission will take him to death's door! Kimihiro has another problem. A cute spirit has given him a Valentine's Day present, which means he's obligated by Japanese custom to return the favor. What do you get a girl who may not even exist in this world?

Kimihiro Watanuki takes a welcome break from his grueling service to the time-space witch, Yuko Ishihara, only to find himself mixed up in the strangest parade of the Japanese magical world. But a slip-up reveals that Kimihiro is a powerless human! How can he survive the festival without being eaten by its dangerous participants?

Working like a slave in Yuko's shop hasn't dammpened Kimihiro's enthusiasm for his cute classmate Himawari-chan, nor his irritation with his too-cool rival Domeki, the guy who always seems to be around during Kimihiro's most embarrassing moments. But when Domeki inadvertently becomes the object of a terrible grudge, Kimihiro seeks Yuko's help. However, the cost for her assistance is steep...

Kimihiro Watanuki's after-school job working for the mysterious witch Yuko Ishikawa has taken a dangerous turn. A recent assignment cost Kimihiro his right eye to a spider with a grudge. Now the missing eye has become the latest must-have item in the spirit world. Even the Zashiki-Warashi, the pretty spirit who has a crush on Kimihiro, has become entangled in the mess... and she's being held captive by an unknown evil!

Without realizing it, Kimihiro Watanuki has purchased a dream. According to his boss Yuko Ishikawa, the mysterious time-space witch, people usually buy good dreams - but Kimihiro's dream is a man-eating nightmare. Even worse, it has come true!
