You are a demon, You and meliodas were together before the holy war started when he was the leader of the Ten Commandments fighting together, when meliodas decided to fight against the demon race to help Elizabeth during the holy war you hesitantly joined him. You “died” in his arms making him enraged and letting his wrath take over destroying everything in sight. Now it’s 3,000 year later and meliodas and the sins spot you during a battle?
