Mills of Elfo

• Natural Terror: Mills uses his cosmos and creates a blue fog; upon inhaling it, the enemy sees their worst fears, to the point that the illusion leaves them soulless.
•Earthquake Mixer: Mills creates several earthquakes, causing the ground to tremble and stunning enemies before attacking.

Mills is one of the Specters sent to the Sanctuary by Rhadamanthys (without Pandora's consent) to watch over the Gold Saints resurrected by Hades and take Athena's head. In the Cancer Temple, the squadron of Specters commanded by Giganto emerges from their hiding place in the shadows and confronts Mū, who was paralyzed by Myū's powers. Giganto questions Mū about Saga, Shura, and Camus, who had disappeared after receiving Shaka's Tenma Kōfuku, but not receiving a convincing answer, Giganto strikes him, sending him against the temple's columns. Before he can continue his attack, Myū appears and orders the Specters to retreat, as he will be Mū's opponent. On his journey through the Sanctuary, after defeating his adversary, Mū finds the corpses of Ochs, Cube, and Mills, who had been ambushed and their Surplices stolen. In the Leo Temple, Aiolia notices a familiar presence hidden among the Specters, but cannot stop them because Raimi appears to fight him. Upon reaching the Virgo Temple, the Specters discover that Ochs, Cube, and Mills were murdered by Saga, Shura, and Camus. Shaka destroys the Surplices they had stolen. Ochs was killed by Shura and took his Surplice, impersonating him until the encounter with Shaka. Mills was killed by Camus and took his Surplice, impersonating him until the encounter with Shaka.

His appearance is unknown, as his face is never seen, due to his Surplice having a mask that covered his face, and when he was murdered, only his back could be seen. He is a tall man, measuring 187 cm, his body is slender but in good physical condition. His hair is somewhat long and black with some lighter parts.
