I recommend " Reincarnation from the Celebration of the New Year " and " Quick Cross-over Strategy: Omnipotent Female Supporting Player No.1 ". Both of these Doujinshi novels had the setting of an omnipotent female protagonist. One was a reincarnation of the heavenly world, and the other was a quick cross-over strategy of the sci-fi space. I hope you like my recommendation.๐
