Warding Mask

Warding Masks are kitsune masks carved from wood by Sakonji Urokodaki for the students he trains. Sakonji has a real gift for woodwork and a fondness for foxes, so every mask he makes takes the form of a fox's face.

He presents the masks as gifts before his pupils enter Final Selection, having placed a protective spell on each one. The masks are worn on the left side of the head, fixed with a cord and leaving the face uncovered. The fox shape draws on Japanese folklore, where the kitsune serves as a messenger of Inari, the deity of the mountains and rice fields, and is believed to ward off evil spirits.

The charm worked into each mask is meant to shield its wearer from danger and call on the protection of the mountain god, ensuring a safe return from Final Selection. The enchantment's reliability is open to doubt, however. All thirteen of Sakonji's earlier students who wore the masks died at the hands of the Hand Demon. Rather than protecting them, the masks let the demon recognize Sakonji's pupils, turning his hatred for Sakonji onto them because Sakonji had imprisoned him on Mount Fujikasane.

After their deaths, some of those students' souls wore the masks over their full faces when they appeared before Tanjiro, a sign of their bond with their master. When Tanjiro's own mask shattered during his fight with the Hand Demon, the spell broke, yet he still survived the encounter.

Sakonji Urokodaki crafts and bestows the masks on his students. Known wearers include Tanjiro Kamado, whose mask carries a sun-shaped design, Sabito, whose mask bears a scar matching his face, Makomo, whose mask is decorated with blue flowers, and Giyu Tomioka, whose mask has heavy slanting brows. Giyu's mask was broken by the first demon he faced at Final Selection before Sabito saved him. The item debuts in Chapter 4 of the manga and Episode 3 of the anime.
