Marquis Blumrush

Marquis Blumrush (also spelled Blumrush or similar variations) is a minor character in the Overlord anime (primarily appearing in seasons 2 and 3).

He is one of the Six Great Nobles of the Re-Estize Kingdom and belongs to the Royalty Faction (supporting the king). He is notably wealthy because his territory includes valuable gold and mithril mines, making him one of the richest nobles in the kingdom.

In the story, he maintains a public appearance of loyalty but is secretly a traitor collaborating with the Baharuth Empire. This betrayal is exposed through the schemes of Nazarick (Ainz's side), leading to his downfall and execution as part of efforts to destabilize the Re-Estize Kingdom.

He has a very minor on-screen role—mostly background or brief appearances—with no major dialogue or development in the anime adaptation.
