World War III has left Earth's surface uninhabitable, forcing humanity to relocate to underground cities. However, these subterranean metropolises cannot produce enough food for their inhabitants, so the highly addictive “Pure Trance” life sustaining pills have become the bulk of the citizens' diets. But eating Pure Trance tends to cause eating disorders such as hyperorexia - extreme overeating - and it's up to the spunky, scantily-clad nurses of Overeaters Treatment Center 102 to help their patients beat the disease. However, in addition to dealing with demanding patients, the girls must also cater to the whims of Keiko, the sadistic, drug-addicted hospital director. How will the nurses fare, stuck between an unbearable job and equally miserable prospects outside of the hospital?
The super-stylized and adorable artwork of Pure Trance and Nokemono to Hanayome mask the darkness of their subject matter. Both are dystopic and laden with sadistic characters, violence, nudity, and some really dark humor. Definitely some of the most (wonderfully) strange shoujo I've ever seen.
A young man comes to live on a small island in the south seas, and resides in a hotel that is far from ordinary – which matches the guests and staff…
Both of these manga have extensive casts of ridiculous characters that are always up to something. Combined with the short chapter length, both manga feel like they're in constant motion- there's not really any downtime.
Both stories are kind of dark (especially Nokemono), but hide it under cute graphics and silly humor.
