Gray Tanaki was an average anime fan until he found himself reincarnated in a Dragon Ball RPG! The difficulty is... nightmare? How can an average man survive when his enemies are smarter, stronger, and canon has gone out the window? By being a badass, of course! Train until your bones break, take over the universe, become a god, and make the harem of your dreams! (Gamer!SI)

"You have been chosen for the [Game of Dungeons: DxD Edition!]" When a bimbo Goddess summons you to a dungeon sandwiched between the supernatural world of High School DxD and the deadly Monster Realm, what's a normal guy supposed to do? Well, becoming a Dungeon Master, scamming the Goddess into being your servant, and using every loophole in the system to profit would be a nice start.

100 Floors? Try 1,000. 10,000 players trapped in a death game? Try 10,000,000. Do you think you’ll be freed in a few years? Maybe in a few decades. A game that should be unbeatable - the impossible ‘Sword Art Online.’ Well, it would be impossible, if not for a certain psychopath. The ‘World’s Greatest Gamer’ will have you all out in no time!
