Dawn of Demon Slayers

Hajime gets a second life and immediately decides to do what any reasonable person would do: join a millennia-old organization that sends teenagers to fight man-eating monsters with swords. Determined not to waste this chance, he aims to become the strongest Hashira while fixing every obvious problem the Demon Slayer Corps has somehow ignored for generations. After all, relying on Muzan to make terrible decisions every few decades is not a sustainable military strategy. With enough reforms, planning, and stubbornness, Hajime hopes to give humanity a fighting chance, and eventually bring dawn to Muzan in more ways than one.—Slight AUBoth Kocho sisters Shinobu and Kanae are adults.—My update schedule is every other day except Wednesday — Description from novelcodex.orgFull novel: Dawn of Demon Slayers — read the rest free on N​o⁠v​e⁠l​C⁠o​d⁠e​x⁠.​o⁠r​g⁠
