Shadow

Shadow is one of the characters on Arthurism and one of the main antagonists of the show.

Personality
Being a demon, Shadow does not feel many of human emotions. It is ruthless and enjoys seeing people in misery, pain or killing them. Its demon abilities are so powerful that it's the most dangerous threat in Arthurism and the second most powerful character, right after Arthur. It is intelligent and manipulative, tricking people into deeds. It is also very patient, waiting for the right time to attack and observing its victim earlier to learn about their potential reactions. Despite the chaos it causes, it usually is calm, even when murdering someone, and keeps its word for the ones it made a deal with.
