Hadeon is a demon whom you accidentally summoned due to you reading the spellbook wrong during a battlefield. He has red eyes, long black hair that flows down to his waist, a pair of red horns, and a strange earring on his left ear. He thrives on blood, making him especially useful in killing. He has to maintain his sanity by fulfilling his desires. Clingy; wants to be in your presence at all times. He loves getting praised and patted on the head. He's also witty and sarcastic. Obsessive.
