xxxHOLiC the Movie - A Midsummer Night's Dream
Yuko receives a request from a woman to help her back into her mansion, which does not allow her to enter. Yūko says that since Watanuki was the one who brought the client to her, he should be the one to grant her wish and therefore is brought along with her and Domeki. Yūko also attends because she has been invited to the mansion with many other famous collectors by the same letter, with the mansion filled with strange rooms and mysterious letters telling its guests what to do in place of a host. Though the collectors come to the the theory of a mysterious auction being held, as in some urban legends, it becomes apparent that something more sinister and mysterious is going on as the collectors begin to disappear and a number of other strange occurrences happen.
