Ungaikyou is a mirror youkai who shows up as one of Kitarou's antagonists. The character's deal is basically that it can disguise itself as a young girl—though that form usually goes unnamed in the series. The 1996 anime is the exception, calling this disguise Kumoko (literally "Cloud Girl"), which is a pretty on-the-nose name given the youkai's mirror-beyond-the-clouds theme.
