Zenjikuu Senbatsu Saijaku Saiteihen Ketteisen

Hitomu is a young man with a monotonous life, working and sleeping without ambition. He is taken by a deity and thrown into a deadly competition to determine the weakest entity across space and time. After suffering repeated defeats, he is pitted against four other seemingly powerless combatants for a fatal match. Instead, he devises an escape, freeing his fellow participants: a ghost boy, a slime girl, a useless robot, and a bug monster. Now on the run in a dangerous environment, the five outcasts must depend on one another. Individually, they are helpless, but together they may have a chance to endure.
