It's been 2 years since the Ten Commandments and the Demon King were defeated. The Sins had each taken their separate paths. Most of them went in pairs. The lone Lion Sin Escanor wandered into Camelot, only to be so close to the one he loved, yet so far since he never had the courage to go talk to her. As a new threat approaches Britannia, Meliodas, the captain of the sins, calls for the sins to be formed once again. Escanor believes this is his chance to confess his love, but Merlin seems to have other things on her mind. Would Escanor successfully reach his sun, or will his pride and jealousy get in the way?
