This is a novel about a former human becoming a demon because of a game . Living the life as a demon from the abyss and crossing to other worlds. His main objective is to destroy and cause chaos among the multi universe. Also this novel is using a ranking that affects both the anime verse and comic verse. Void becomes a primordial demon and step by step changes the view of all races about demons.demons are not weak , demons are pure chaos. Note the MC is cruel and indifferent to life . A dark novel.. don't expect a son of destiny... Infact void isn't a villain he is much much cruel . Don't read if u are weak minded. The start is a little bit rough but I think after chapter 5 the novel is okay .
