Kegare King from Twin Star Exorcist is a Planetary Destroyer being from the corner of the Universe that was fed with the negative energy of living beings. Also, using Sakanashi as a host, Kegare King is capable of merging layers of The Magano, an alternative dimension created by Abe no Seimei to seal the Kegare King. This process ultimately leads to the destruction of The Magano, freeing Kegare King to destroy the Planet Earth.
