For those who don't know: among the many figures associated with Matarajin was Hata no Kawakatsu, known as a close friend of Prince Shoutoku (A.K.A. Miko) who helped him create what would become Noh theater (and as a consequence, was also Kokoro's father in a way). One of the masks created for this form of theater was the Okina mask, which would go on to be seen as a symbol of Matarajin.
