Watanuki's gratitude becomes the entire show. Two episodes that understand the weight of small kindnesses, impossible choices, and what you owe someone who saves you without asking for anything back. The Shunmuki OVA doesn't resolve, it sits with you in the space between what was promised and what can never be repaid, which is exactly where xxxHolic lives.
Kimihiro Watanuki works at the odd shop of Yuuko as payment for his wish to be rid of his ability to see spirits. In this two-episode OVA, a direct sequel to xxxHOLiC: Kei, he and his friend and rival Shizuka Doumeki share a meal with Kohane Tsuyuri and her grandmother, and they think back on how meeting one another has changed them. Later, Doumeki's grandfather Haruka appears to Watanuki in a dream and asks him to find items in the family temple's storeroom. Searching with Doumeki, he discovers that each object points to the next, turning the errand into a treasure hunt that draws them into the world inside the books. The OVA blends comedy, drama, mystery and supernatural elements, and it features some unexpected guests.
