The Seven Deadly Sins, with the help of Elizabeth Liones and Hawk, have reclaimed the Kingdom of Leones from the Holy Knights. It's finally time for them to enjoy the quiet lifestyles they fought for. The Sins are accompanied by their pals in their carefree, fun-filled time together, which includes inedible meat pies, overdue battles, unexpected stalkers, and the butterflies of first love. The tranquility is disturbed, however, by the foreshadowing of a new threat, bringing with it the indications of Holy War and threatening to destroy the quiet of the Sins' leisurely days.
