Hakutaku (Half-Beasts)

Hakutaku are some of the most intelligent Youkai ever in existence, and they have a habit of recording history and events that occur. They are also usually depicted as having one or two horns, and sometimes even have multiple eyes on their body. Every thousand years, a Hakutaku will visit the most intelligent and ambitious person in the country, whether they be an Emperor or a simple Farmer, and will bestow upon them knowledge of events that will happen, that have happened and that are happening now. A good example of this was when a Hakutaku granted a certain Emperor the knowledge of the amount of Youkai in the world, and how to escape or defeat them.
