Past

Under the holy war, Meliodas, the demon kings son, betrayed the demon race for a goddess, but what actually happened? Was that really true?

Now, 3000 years later, he has his group called the seven deadly sins, his 'lover' Elizabeth and many other people. One day, Meliodas didn't act as himself, or rather, he started act as himself. The ruthless, cold hearted murder that is now trying to brake the demon clans seal.

What happens when everyone find out the truth of the cursed lovers? That it actually is 'the brainwashing'.
