Demon Slayer: The Silver Stinger

What happens when modern medical science meets the dark curse of Muzan Kibutsuji? Ripped from his 21st-century life, seventeen-year-old chemistry student Ren Asakura awakens on Mount Ooe stripped of his humanity. He possesses no Demon Blood Art of flame or ice. Instead, his very biology is a weapon: Necrotic Hemoglobin, a lethal acid-blood reaction that turns a demon's own circulatory system against them. Equipped with custom dual rapiers, the "Stray Demon" of Mount Ooe enters the night. Witness the story of Ren Asakura—the demon who fights with the blade of a slayer and the science of a monster. *** A/N: It'll have an intertwining timeline (past and present) with the same main character. Read it for the full details, since explaining it here would kinda spoil it. Update schedule is Saturday - Wednesday (Thursday / Friday = Days-Off).
