• Roa used the Scarlet Blade to burn every fragment of Muzan Kibutsuji, then asked whether Muzan had anything to give him.

• A voice in the landscape called Muzan food, while Roa checked his updated system panel and watched Muzan’s head turn to ash as the Infinity Castle collapsed.

After Muzan Kibutsuji’s death, demons across the world began to explode, and Roa prepared to leave the Demon Slayer world.

After Muzan Kibutsuji’s defeat, Roa forced the government’s priest to back down from threatening the Demon Slayer Corps and exposed the soldiers’ weapons as ineffective. The Corps returned to headquarters to consider life after the demons, while Roa learned his adoptive family’s estate had been destroyed and asked Kanroji Mitsuri to join him in the future.

After a month of training Kanroji Mitsuri in the Sword God Style, Roa returned to the Jobless Reincarnation world and checked the rewards for clearing the Demon Slayer world. He learned that summoning characters required permissions, but the chapter left him puzzled by Kazuto Kirigaya’s high cost.
