Watanuki has finally stopped running from what Yuuko made him become, and now he's just quietly breaking under the weight of keeping his promise. Ten years later, he's not the desperate kid anymore, he's the man trapped in the shop, and the show knows the difference between survival and the life you're left with after surviving. Every visitor who walks through that door is asking him to care again, and he does, because that's the curse he accepted.

A decade has passed since the events of Shunmuki, and a melancholic Watanuki now runs the shop that once belonged to Yuuko, keeping a promise he made to her before she departed. He spends his days granting wishes for those who come to him, living quietly with Maru, Moro and Mokona. Old faces still drop by: his steadfast friend Doumeki, and Kohane, a former psychic now studying folklore under Doumeki at university, who bring him a case well suited to the shop. Later, Doumeki's grandfather Haruka visits and asks Watanuki to look into his grandson's dreams. Inside that dream world, Watanuki sees their past adventures from Doumeki's point of view, uncovering truths from ten years ago and secrets about the bond between them.
