Plot: Antisocial misfit Ryohei Arisu wanted nothing more than to leave his mundane life behind, but a wish on a firework transports him to the post-apocalyptic Borderland, a sinister parallel reality where danger lurks around every corner and survival is not guaranteed. To live to fight another day, Ryohei and other unwilling contestants must win a series of games, each deadlier than the last — but returning home means putting not only his skills, but also Ryohei's humanity to the ultimate test
