Goddess of Death!
The Death Kingdom is controlled by three Subsidiary Gods. The Goddess of Death Aztemo's main consciousness has been constantly doing sit-ups; Schrödinger's cat, Aztemo in the coffin board, have become synonymous, she's the weakest link right now.
A part of Aztemo's consciousness resides in Wayne's right eye, now fully corrupted, allowing him to manipulate it at will. In addition, he holds Monica and Yuliya, two avatars of Aztemo, in his hands.
There's a high chance of successfully taking action against the Death Kingdom.
Regrettably, as a Death Knight, Wayne has never visited the Death Kingdom, nor communicated mentally with the Goddess of Death. The closest he came to the Death Kingdom was during the Underworld Great Tomb encounter when Rone feared he'd storm in; sealing the space passage upon entering the Divine Nation, leaving him no chance.
