5. 255 穿 Transmigrate into Demon Slayer as the First Hashira 穿越鬼灭当初代柱 Tuantuan Is a Big Pig's Trotter团团是个大猪蹄子Anime Fanfiction625k WordsOngoing Told from the perspective of a “witness across time” in Demon Slayer, this story spans the birth of the Breathing Style through the battle at Infinity Castle, from the first generation of Hashira to the demon’s defeat in the bamboo grove.
