The manga is mostly about survival and action.
It's a manga that I enjoy and still waiting to get to the next chapter.
The idea is that people are being sent to play a real-life game called BTOOOM! In which people really kill and die. I think it's good because the plot in where people get transferred into a game is getting mainstream. This one is real, and the weapons are logical.
I've always liked a survival manga like this. It also gives out some strategies on how to deal with the enemies, which is good.
The manga also holds some good meanings inside it. Which I think-- is the most important thing of a manga.
It is pretty ecchi, though. Remembering that this is a shounen manga.
