Kaitai

Kaitai summary:

From Baka-Updates: Kaitai is a science-fiction-ish BL story of bio-engineered humans, sinister policemen and moody scientists with mysterious pasts. Set in a depressing, fictitious London from somewhere in the near future, this manga is representative of Ishihara's earlier, non-yaoi works; rough, sketchy artwork accompanied by an interesting plot the likes of which is rarely seen in the shounen-ai demographic.
