I'm not sure if this is old news, but I'm getting it to you as soon as possible:
Holic updated! Yuko says she shall disappear, and Watanuki vows to stay in the shop, waiting for her and making her wish come true: to exist. After Yuko dies, Watanuki will finally be free from his haunting visions. How will that change him?
