Zunou to Inou ni Kinniku de Shouri suru Death Game: Zunousen ni Maiorita Saikyou no Baka

Synopsis

When he woke up, he was chained to the wall by a poisoned collar... Yes, this is a death game hosted by a demon. A murder game where one should use their bestowed supernatural powers and strategies to kill other participants and grant their own wishes... Or so it was supposed to be, but a "Muscle-brained" idiot, Tsuyoshi Kabajiima, who rips off the fastened collar and smashes through the closed iron door, has wandered in, causing the game to completely collapse!? The strongest death game tale, unpredictable even for the demon, begins here!! (Source: Overlap, translated)
