Many of these designs are based upon Japanese folklore. Yōkai ("ghost"; "phantom"; "strange apparition") are a class of supernatural monsters, spirits, and demons in Japanese folklore. The word yōkai is made up of the kanji for "bewitching; attractive; calamity" and "spectre; apparition; mystery; suspicious". Yōkai range diversely from the malevolent to the mischievous, or occasionally bring good fortune to those who encounter them.Yōkai often possess animal features, yet others appear mostly human. Some yōkai look like inanimate objects, while others have no discernible shape. Yōkai usually have spiritual or supernatural abilities, with shapeshifting being the most common.
