Meet Kazahaya and Rikuou. By day, they are two ordinary pharmacists; by night, their boss has them filling special prescriptions for clients.

While working at the Green Drug Pharmacy, co-workers Kazahaya and Rikuo go on secret assignments for their boss Kakei that require Kazahaya's gift of seeing the memories of anyone he touches in order to complete them.

Sent by Kakei to enroll in a mysterious high school, the boys must retrieve an equally mysterious ring. But Kudo and Himura discover that there is more to these hallowed halls than is out of the closet. And their discovery may very well uncover more about each other than they truly want to know. When the whole school decides to celebrate a marriage, more is set aflame than just hearts—which means that time is running out for the boys, who must find that ring before anyone thinks twice...about their relationship.

Au milieu de lointains souvenirs, une silhouette ensanglantée... Encore frappé par une vision, Kazahaya reconnaît Tsukiko, la mystérieuse jeune fille qui hante son partenaire, Rikuô. Ensemble, les deux employés de l'étrange pharmacie Midori vont se lancer dans une nouvelle enquête paranormale, et faire la rencontre de l'énigmatique Kimihiro Watanuki, propriétaire d'une boutique où les souhaits se monnayent. Mais au bout de la piste se cache un lien secret entre Rikuô et celle qu'il veut à tout prix retrouver…

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.

Kudo Kazahaya’s name evokes the wind, which is given to warn him that one day he, too, might disappear. Once he almost thought his time had come—until he was rescued by the dark, handsome, and equally mysterious Rikuo Himura. Now they both reside at Rikuo's workplace, the Green Drugstore—a shop that dispenses not only medicine but the secret powers of both Rikuo and Kazahaya—from which the pair embark on missions into the paranormal at the bidding of its strange proprietor, Kakei. CLAMP's Tsubaki Nekoi takes the lead in portraying the stylish boys' love of Legal Drug. This Legal Drug omnibus leads into the sequel Drug & Drop, coming soon from Dark Horse Comics!
