Yukkuri Seijas are a new type of Yukkuri that are mean spirited and tricksters. Unlike other trickster yukkuris, such as Tewis, Seijas enjoy playing pranks and tormenting other yukkuri for the fun of it and with no gain. They like to manipulate Shinmyoumaru-types, who look for protection in Seijas, and flip other yukkuris upside-down leaving them helpless.
