Game-loving high school student Akira Shiroyanagi survives an encounter with a monster, only to be fatally wounded by a girl named Mion. Soon after, he wakes to find himself part of an "ability focus group," a large group of people granted powerful abilities and forced to fight - and possibly kill - one another!
Matches can only be resolved 
through admission of defeat,
،تنتهي المباريات فقط بالاعتراف بالهزيمة
Die Kämpfe enden in Aufgabe,
El combate solo terminará
tras una rendición,
El combate solo terminará
tras una rendición,
Le duel s’achèvera
en cas de forfait,
Gli scontri terminano solo a seguito di resa,
As partidas só vão terminar
com declaração de derrota,
Поединки продолжаются до признания
поражения, потери сознания или смерти.
