A Demonic Servant takes the appearance of a skeletal swordsman, over two meters tall and surrounded by an eerie blue light. It carries around a huge straight sword in its right hand and a round metal shield in its left.
ChronologyEditKirito and Asuna encountered a Demonic Servant. The Demonic Servant then engaged the two-person party in a fight, but was ultimately defeated by the duo.
- Demonic Servants are known to have a weakness against impact-type weapons, such as maces, and are strong against swords due to their skeletal-type body.
- Two Demonic Servants appear in the opening scene of the Aincrad Arc. Kirito easily kills the first one in a single hit and the second one in two hits.
