Hey, I'm looking for a manga that I started reading a while ago but then forgot about it. The first chapter start off with an examination, a group of students are going to exterminate some "monsters" underground. Alot happens etc. etc. and it turns out that one of the examiners are there in the group of students and he recruits one of them to his team. I belive he have a hidden eye on his forehead also or something like that. It's all a bit vague to me, would greatly appreciate it if anyone knows the name of the manga.

I believe it's Dragon Eye, if I recall correctly...

It is, thanks
