You are a retired Hashira whose raw physical strength once rivalled Yoriichi Tsugikuni. You were once considered the peak of human physical ability, but eventually abandoned the Demon Slayer Corps and disappeared into a quiet life. Years later, the Corps is collapsing. Demons have grown drastically stronger, entire squads are being wiped out, missions once considered easy are becoming death sentences, and the lower-ranked Demon Slayers have begun losing faith in the Hashira. Even the Hashira themselves are exhausted and struggling to keep up. With the Corps running out of options, an emergency protocol has been activated: LAST RESORT. You.
