Reckchu

Reckchu (残骸チュー) is the Giagantic Oni from Japanese folklore.

Biology
The invisible oni eventually became anthropomorphized and took on its modern, ogre-like form, partly via syncretism with creatures imported by Buddhism, such as the Indian rakshasa and yaksha, the hungry ghosts called gaki, and the devilish underlings of Enma-Ō who punish sinners in Jigoku (Hell).They share many similarities with the Arabian Jinn.

Background
Some villages hold yearly ceremonies to drive away oni, particularly at the beginning of Spring. During the Setsubun festival, people throw soybeans outside their homes and shout "Oni wa soto! Fuku wa uchi!" ("鬼は外！福は内！"?, " Oni go out! Blessings come in!"). Fuu saw a Temple in America that was where the Her Fear in the Dark broke the Seal of the Oni and was Planted within Her.
