Mission, annihilate the error.

The child - weapons’ story of fate as they grew up together...

Tokyo, 2018.
Zombie like creatures called "Error" began to eat people suddenly appeared. The boys and Girls known as "Mistiltain" are developed and nurtured for annihilation. The Mistiltain who met each other at the age of five, and had together many stories of death and torture, have their roads of fate rip them apart...

Note: No new chapter since January 2018 Issue of Monthly Asuka. But nothing has been officially announced. The mangaka has started a new series since then, so the series may have been cancelled.
This is likely due to the series’s high volume of bloody violence, gore and disturbing imagery.

It is similar to what happened to CLAMP’s series, X(X/1999); which also ran in the same magazine.
