Hellhounds (地獄の猟犬) are a special breed of Demonic hounds that originated from YGGDRASIL.
Though Hellhounds look like large dogs, their eyes are filled with an infernal intelligence, and in place of drool, flames leak from their maws.
Hellhounds have a fiery breath that froths from their mouths, enabling them to burn their foes to a crisp.
