Haven Keeper

The Haven Keeper is the lord of the underworld, said to be one who will destroy all planes of existence.

He was sealed in the place he practically created by The Senator, Satoshi Mayura, Shiki-Maru, Ranju Nairoga & Muta Jushin.

The Haven Keeper appears as a titanic golem, almost immobile with how slow he moves. Even while restrained with demon seals, his presence alone can harm someone greatly.
