A group of kids bond together in the Lightless Realm, a pitch-black abyss, only to be split up and sent back to their home dimensions. Years later, these kids rejoin to use "Vess" robots to combat "Admonitions," monsters that come from the same emptiness. Their efforts, however, only serve to delay the Lightless Realm's encroachment on their world. When a new adversary in the form of a "Corpse," whose song is said to kill everyone who hears it within nine days, arises, their lives take a dramatic change. The moment the gang hears the "Corpse Song," they all start to withdraw and get mired in their own troubles, endangering the future of civilization.
