XXXHolic volume six finds Watanuki on his own, as Yuko has gone to "make gods" in Tsubasa, the crossover manga starring Sakura and Shaoran. Watanuki had become a kitchen slave, making treats for Yuko and Motonoki as they downed gallons of alcohol. At last, he is going to get a vacation! But rather than have free time, Watanuki becomes embroiled in a friendship that might kill him.
In the park, he meets a beautiful woman. They quickly become like a mother and son. But something is wrong, and Domeki might have to take drastic measures to help his friend. This story takes up the last two-thirds of the volume. The first third is a cute story where Domeki and Watanuki journey to the spirit world with the help of a magical lantern.
The cultural notes in the back are interesting and helpful, more so than any other manga I have read. Anyone who has read all the notes from XXXHolic will have an above-average knowledge of Japanese culture.
And, as usual, Yuko's outfits are ABSOLUTELY GORGEOUS!!!!! Just look at the cover!!! The CLAMP studio is SO skilled at designing clothes.
