From the Start, Destroying Konoha First Shouldn't Be a Problem, Right?

[Dark fiction] + [no female lead] + [Infinite Flow] + [decisive and ruthless] + [no saintly hero] + [ensemble cast] + [team battles] The Akatsuki, the strongest force in the Naruto world, suddenly appeared during Konoha's Chunin Exams. Its eight core members slaughtered their way through Konoha, leaving no one untouched... "They're the greatest evil in the world..." "Only war can make people remember pain..." "Only pain can make people cherish peace..." "The Akatsuki is the strongest evil force there is, here to make people remember pain!" "Heard someone got mobbed and isn't happy about it? Uchiha Itachi, Uzumaki Nagato, Orochimaru, Hidan, Uchiha Obito, Hoshigaki Kisame, Deidara, and Zetsu all smiled..." What era is this? Who still insists on one-on-one fights? A group brawl is way more fun... The Akatsuki has boundless ambition: a one-on-one means you fight all eight of us by yourself; a group fight means all eight of us beat you up together... [No matter who you are in the Myriad Worlds, we're going to beat you all up!]
