   Summary

   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)
