Oni (鬼) is an evil character in Japanese folklore, with a long history of being a ruthless person who loves almost anything else. From chilling scary kids at festival seasons to guarding entrances to hell, they are found all over Japan and are known to be easy once you know where to look. While most have a reputation for being monsters, there are also some friendly oni. sometimes they welcome visitors to Beppu onsen or bring happiness to the Kunisaki people - not all of them are evil.
