*No spoiler here* Story: In short, it's a seinen, thriller, survival manga about a selfish dude and a good-heart girl were sent to another place and ordered to kill human. Reader will know the story in the same view as main character, so it's like a puzzle that you have to collect many pieces to know what is all about. Many hidden along the story and mangaka put many 'symbols' in the story for us to find out. Very similar to GANTZ (character personality, suit, have to play along god's game, have to kill someone you don't want to) and other battle royale manga. Art: it's good but notthat great.

Character:
Every character have strong personality. Male character is shit and chicken at first. I have read 15 chapters now and still the same, no improvement yet. (But remember GANTZ and other manga, MC improved they personality at 100th+ chapter, not that fast right).

Overall 7/10
If you like survival manga and like GANTZ, go read it.
