Anime That Need a Second Season

Not exactly a season 2 but I'd like to see a continued anime based on a different ending from the Death note or at least something interesting like Light becoming a Shinigami. The ending was so forced and contradictory to the whole show, at first they show Light as someone who barely makes any mistakes and then they make him trust others blindly which doesn't make lot of sense to me. Besides from that, I'd also like to see a new season of No game no life or made in abyss
