Specter
Complete | kisaragi hirotaka | 2000 released
A strange parasite is created and researchers just can´t get enough test subjects, which is not easy since the blood has to match. Producing a female parasite is even harder but possible. The story is far too short to introduce the characters and the world properly. Thus it seems rushed and even though it should have been shonen-ai it can´t really be considered as such, since the main cast does not really show affection for each other. It seems more like i feeling of protection for kindred spirits. Two guys in the same situation. I can´t really see the potential love interest.

Not really Shonen-ai but a bit touchy feely
