Alright, hope this ain't annoying people that I make these.
I, personally, have yet to read Legal Drug but it is on my list to read.
Creators: CLAMP
-Main Artist: Tsubaki Nekoi
Start date: 2000
Current state: On Hiatus
Volumes: 3 as of 2005
Summary:
Kazahaya Kudo collapses one snowy night on the verge of death while running from his past. Rikuo Himura rescues him and takes him back to the Pharmacy he works at called Green Drugstore. Kazahaya starts working at the store, feeling in debt to it's owner, Kakei. The two work regularly during the day, but are sometimes used by Kakei for strange jobs outside the store that use their supernatural powers.
Side Notes:
- Legal Drug characters appear in many of CLAMP's other works, so be looking for them!
- What has been released so far is only 1/5 of the intended story. At the 2006 Anime Expo, Clamp director Ageha Ohkawa has explicitly stated that "Clamp will be resuming it in the near future." TokyoPop posted a reference to Volume 4, however the manga has not been continued in Japan nor have any new materials been published.
Wikipedia it. You'll get more info. xD
