◆ Youtou Muramasya: Knives used in earthwork now. The former knife was repaired due to serious damage, and as a result, Youtou Muramasya, the demon knife, was borrowed by mistake. After being possessed, you can never get rid of it. His personality was once transformed into the Fourteenth Palace, but he finally subdued Youtou Muramasya by his own will (see the chapter on turmoil for details).
