You wake in a strange world unlike anything you knew, immediately attacked by creatures that are unmistakably real despite the dreamlike setting. Among the displaced souls gathered here — each pulled from a different world — a strange girl is waiting. She explains that this realm was built from souls harvested from other dimensions and will keep stealing them until those source worlds cease to exist. The only way to stop it is to sever the bond between this world's evil master and yourselves — which means freeing every trapped soul first. She asks for your help. You have no better option.
