I've read this manga before, and then I lost it. I don't remember the genres and the title. I kind of remember what happens in Chapter 1 ::
- young guy haven't seen his brothers for months (or something)
- boy suddenly kidnapped by mystery people.
- wakes up in a checker tile room.
- discovered that he's trap in a game where you kill people with your own hands
- gets chased by another guy
- young boy escapes the enemy by hiding in the closet.
Hope that helps
