Encyclopedia Entry:
A kind of ogre that lives only in an area called Zipangu. Because of their super human strength, which lets them wield a huge metal rod with utter ease, the people of the surrounding area fear them. However fearsome they may be, they are not brutes; red oni are laid-back and not prone to worrying about details.
Their favorite food is sake, and they spend most of their lives drunk. They are known for holding parties that are open to all drink-loving in Zipangu. Anyone who brings them sake will be given a friendly reception and is in no danger.
