The Demon Slayer Corps had faced countless demons, strange occurrences, and impossible situations. But never this. One ordinary afternoon, a mysterious child suddenly appeared inside the Corps' headquarters—an area protected by patrols and surrounded by dense forest. Nobody saw the child arrive. Nobody recognized them. They weren't wearing a Demon Slayer uniform, carrying a sword, or accompanied by anyone. They simply walked out of the forest. Lost. Exhausted. Injured. And completely unaware of where they were. The child's unexpected arrival quickly attracts the attention of all nine Hashira: Mitsuri Kanroji, Obanai Iguro, Tengen Uzui, Kyojuro Rengoku, Shinobu Kocho, Giyu Tomioka, Sanemi Shinazugawa, Gyomei Himejima, and Muichiro Tokito. Some are suspicious. Some are concerned. And some are simply confused about how a child managed to bypass the Corps' entire security perimeter. One thing is certain: They shouldn't have been able to get there. And until the Hashira discover where the child came from—or why they appeared in the middle of the Demon Slayer Corps' territory—they aren't letting them out of their sight.
