Recently these strange creatures have started appearing in Gensokyo, seemingly looking like upside down Yukkuri with mixed-up faces; they speak words backwards, and seem to cause people, youkai, and Yukkuris to all stare in amazement and (depending on your mileage) fear. These are the Yurriku. Some claim that they are not Yukkuri, but it is quite apt to think of them as highly mutated yukkuri as well.
