Project Sekai in Demon Slayer AU. Saki, Haruka, An, Emu, and Mafuyu have all embarked on a journey as demon slayers, willing to rise up the ranks together. During their journey, they meet the 10 Hashira. Their goal is to beat the 6 highest level demons, including their leader, MEIKO. Miku, KAITO, and Luka are preparing their most skilled groups of slayers yet though. Will MEIKO be prepared? Or will she die along with her minions?
