xxxHOLiC Omnibus 7 collects volumes 18-19 and features story and art by CLAMP.

The longer Watanuki resides over the shop, the stronger he gets and the more he learns to rely on his friends in the way his friends have relied on him. But as his powers grow with the passing of years, his memories of Yuko also grow distant. Will the current shop master ever be reunited with its former owner and will Watanuki ever be able to leave the shop? Find the answers to these questions and more in the final omnibus of xxxHOLiC.
