Reincarnated In Demon Slayer with A Zanpakuto

Nanajūhachi Asuka, a soul from the 78th district of Rukongai, is cast into the world of Demon Slayer as a disposable experiment. Lacking a “system” or “cheat-codes,” he relies solely on his raw Reiryoku (spiritual power) and the survival instincts of a street dog. Asuka is taken in by Tetsushin Arisaki, mastering Wind Breathing alongside his peer, Suzune. This peace is shattered when Lower Rank Two, Rokuro, massacres their home. Master Arisaki sacrifices himself, triggering the awakening of Asuka’s unique ability: Nugata—the power to devour demon essence and convert it into spiritual energy. Driven by cold vengeance, Asuka joins the Demon Slayer Corps. His presence at Mount Natagumo changes the tide, as his “serrated” strikes—infused with spiritual pressure—permanently stall demon regeneration. This “new variable” catches the attention of Muzan Kibutsuji, who begins purging the Lower Ranks to prepare for this emerging threat. Through training at the Butterfly Estate and sparring with the Mist Hashira, Muichiro Tokito, Asuka realizes a vital truth: traditional Wind Breathing is a “shoe that doesn’t fit” his spiritual nature. He begins the journey to transcend established styles, seeking to forge an Original Breath that bridges the gap between a Soul Society ghost and a mortal swordsman. — Description from novelcodex.orgFull novel: Reincarnated In Demon Slayer with A Zanpakuto — read the rest free on N​o⁠v​e⁠l​C⁠o​d⁠e​x⁠.​o⁠r​g⁠
