Meta:Banishment

RPG Information
Banishment (Special Ability, Oni Lord only)

All Oni Lord had the power to banish its physical form to Jigoku to prevent its death, but could not return again unless summoned. It might send its spawn to the Mortal World via the Festering Pit or other portals, but could not free itself without assistance. Such a thing was said to have happened many years ago to the First Oni, the Maw, and Akuma no Oni.
