Kimihiro Watanuki's life has never been truly ordinary. Beyond his ability to see spirits, this sequel to xxxHOLiC shows him continuing to toil for Yuuko, the eccentric owner of a peculiar shop, who promised to remove this power from him. However, this supernatural woman can only fulfill that promise once he has worked sufficiently to earn his wish. This is the rule for anyone who enters the shop to have their request granted: a compensation equal to the value of the wish must be paid. In this strange shop that exists between the world of the living and the dead, Watanuki finds himself performing household chores for the seemingly lazy Yuuko and her companions, while also assisting clients. Together with his classmates, his supposed romantic rival Shizuka Doumeki, and his crush Himawari Kunogi, Watanuki deals with the various misfortunes affecting Yuuko's customers, as well as those that closely follow him and his friends.
