Kaguya

Serving as the primary antagonist in Castle Beyond the Looking Glass, this mysterious figure claims to be a fallen angel seeking immortality through the legendary Celestial Robe. Once imprisoned within a mirror, she is liberated when Kagura and Kanna gather five magical treasures to form a powerful pentagram. During the chaos, she uses her mirror to force a transformation in Inuyasha, though her pursuit of the moon eventually ends when Miroku absorbs her into the Wind Tunnel.
