The original manga is already completed but no one has translated for years.
The manga is a survival, kill-or-be-killed manga with a great art. It's about high school students force to fight with their given power (they just started to get used to the power so some died before able to use it). It's very unique but it shares similarities with Kami Sama no Itouri or Real Account or Mahou Shoujo of the end or Dolly kill kill (if you know some of these).
