Only two can survive and win.
2 Volumes (Complete)



30 men are shanghaied onto a small uninhabited island to become unwilling participants in a Battle Royale. The rules are simple. Only two people can survive and those two must have sex by the end of the game.
Our main couple consists of a detective and a dexter-like serial killer (who only kills bad guys) he was chasing. The latter also has a special superpower, namely, he can sense other people's killing intent which comes in handy in their particular situation.
The duology is action-packed and definitely a change of pace from your regular BL. No bishonens here, either. Most characters are pretty beefy. I wouldn't even call this a BL necessarily. The mains do have an intercourse at some point, but it's due to the circumstances they are in, not because they have feelings for each other. However, at the end, you can tell there is a spark there, a possibility of something more developing eventually, but unless the author comes up with a sequel, I think this manga is more of a bromance than a romance. (Which is fine, I'm just mentioning that so people know what they are getting into.)
I do hope for a sequel, though.
