あらすじ

The top student and the class teacher is mysteriously transported along with the whole classroom into the gaming world. A world that determines life or death through an elimination system based on accumulated marks. A system setting that is constantly and mysteriously changing, randomly matched "team members" from various backgrounds, undercurrents and benefit-based entanglements within "legions". Here, everyone is carefully selected from the other challengers, but failure means death, and winning is the only way out. How will their lives turn out with this twist of fate?
