In this follow-up to xxxHOLiC, Kimihiro Watanuki's peculiar life continues as he toils under the enigmatic Yuuko, the shop's peculiar owner, who pledged to free him from his spirit-seeing ability. To realize his desire, Watanuki must labor until he earns his wish, a common rule for all visitors seeking fulfillment at the shop. Amidst Yuuko's supernatural realm bridging the living and the dead, Watanuki not only performs chores for the seemingly indolent Yuuko and her entourage but also aids the clientele. Juggling schoolmates like the stoic Shizuka Doumeki and his crush Himawari Kunogi, Watanuki navigates the trials afflicting Yuuko's clients and his companions, all while facing personal tribulations that intertwine with his friends' fates.
