Gashadokuro/Origin

Origin
In Japanese folklore, Gashadokuro, (がしゃどくろ) also known as Odokuro, or ("starving skeleton") are giant skeletons that are fifteen times taller than an average person. If a Gashadokuro sees a human, it will grab it and attempt to bite its head off with its giant teeth. Gashadokuro are created from gathering bones from people who have died of starvation. The only way a Gashadokuro can be detected before it appears is by hearing a ringing in one's ears. People who are being targeted by this mammoth- sized skeleton hear extremely loud bells ringing throughout their ears. Gashadokuro targets people when they are alone. It roams about after midnight.
