xxxHolic Volume 16: 10/16/14
xxxHolic Volume 16 by CLAMP marks the start of the Rô series. Yûko is gone and Watanuki in hopes to find her and perhaps shock of her disappearance, has decided to stay in the shop to keep it running.
Watanuki's existence, and perhaps the shop's continued existence, are tied together. As long as he stays within the confines of the shop he won't age and the shop won't disappear. He therefore needs help from Dômeki and his other friends met over the course of the previous volumes.
Throughout the series, Yûko imparted the importance of personal decisions in the flow of life. Further more Yûko reminds Watanuki that hitsuzen (http://www.tsubasachronicle.net/holic/hitsuzen.php) describes the coincidences of life, not fate. It seems now that Watanuki is trying to avoid both decision making and hitsuzen. He's in a self imposed stasis. He says he's doing it to find away to restore Yûko but it's more likely that he's paralyzed by grief and fear.
