If you liked the xxxHolic manga, the Anime-Planet community thinks you'd like:
Both manga feature a shop which grants wishes and in both cases the price for those is not cheap. Both series are a little dark (but xxxHolic probably had darker stories).
a store that sells skill, and is thereby grant for their desires? there is nothing more like xxxholic, even the same feeling of altruism above all of the characters and similar...
Mushi are another form of life which live parallel to our own natural world. The source of many myths and superstitions, they exist according to their own natural laws, and can be both beneficial and dangerous depending on circumstances. Ginko, a traveling mushishi, investigates and helps out wherever the mushi have become a problem. Yet Ginko himself is marked by the creatures he researches, and he carries the weight of his past with him.
Mushishi and xxxHolic, while slightly different in tone, both focus on a more supernatural side of life. So while xxxHolic focuses more on cautionary tales and Japanese mythology and Mushishi looks at the mysterious lifeforms known as Mushi, if you liked the supernatural aspect of one then it is well worth checking out the other.
Both mangas is practically talking about same things. It have same atmosphere in them. Yes, story lines may differ, but both of them give you similar reading plasure.
Natsume is lonely; he has an ability that separates him from others: he can see and interact with spirits. Soon, however, Natsume discovers that he’s not alone: his grandmother Reiko also had the gift. But things get hectic and possibly dangerous for Natsume when he finds out that he also inherited the 'Book of Friends', a book that contains the names of all the spirits Reiko defeated and subjugated. He finds himself hounded by his grandmother's underlings and, with the help of a 'cat' charm spirit, decides to free them from the Book's shackles, as well as protect the book from those who seek to misuse its power...
Though xxxHolic is more based upon fate and mystery, both of these manga feature young boys with the ability to see things they wish they couldn't and how they cope with their gifts. If you liked that in one, you may enjoy the other.
Spirit world, all kinds of shananingans is keys to both these mangas. Even Natsume and Watanuki is similar in some way like Madara is very similar with Yuuko. Liked one - deffinetely try another.
Mitsuo Shiozu is a reclusive high school boy with a special gift: he is able to see and communicate with ghosts. However Mitsuo sees his talent as more of a curse, especially when he comes into contact with a female spirit who takes over his body and uses it to confess to a boy named Hasanuma in front of the entire class! Though while these ghosts are tiring him out by possessing Mitsuo whenever they feel like it - making his school life a misery in the process - he still hopes to grant their wishes and help them move on. But with such a special power, many spirits requiring help, and a growing number of male admirers - including the increasingly persistent Hasanuma - Mitsuo's life is sure to be anything but quiet or lonely.
Ignoring the shounen-ai aspect of Eerie Queerie, both of these series focus on a high school student with the ability to see spirits. If you liked this part of one and seeing how the protagonist develops with his experiences then you may well enjoy the other.
The protagonist of Ga-Rei and the protagonist of xxxHolic are quite similar. They both have a ghost problem which is: they can see ghosts and much to their own dismay, ghosts really like to torment them. As the story progresses, both of them end up having a job where they have to deal with ghosts and spirits. Did I mention that both of those manga feature lots of elements take from Japanese lore? Anyway, if you liked one go check the other too.
