Drug and Drop Volume 2 — CLAMP

After completing Watanuki's request, Rikuo disappears upon his own ever-mysterious purposes. Fraught with worry over Rikuo, and bearing the new burden of "carrying memories" all by himself, Kazahaya makes a rendezvous at an unknown house--whose signpost has his family name! From behind the wisteria tree appears something even more unexpected...a tiny angel named Kohaku.
