The Seven Deadly Sins may have ended the tyranny of The Ten Commandments for now, but that doesn't mean all is peaceful in the kingdom. Separated from the rest of The Sins, King and Diane strike a deal with former Commandments Gloxinia and Drole, and agree to undergo special training--which sends them to a Britannia 3,000 years in the past, right before the end of the Holy War! Can the pair navigate this strange past--and a threat more powerful than The Ten Commandments?
Only six of the Seven Deadly Sins have been located so far, so our heroes travel to the kingdom of Britannia to find the final missing member of their group. New adventures await them, along with powerful new adversaries: an elite group of demonic warriors known as The Ten Commandments!
The kingdom of Liones is thrown into turmoil when the king's Holy Knights are corrupted by a distinctly unholy demonic power. The land's only hope is a band of powerful warriors known as The Seven Deadly Sins - an exiled group of oddballs who seem to spend as much time fighting each other as they do fighting their enemies. Princess Elizabeth desperately seeks their aid, but the leader of her would-be saviors turns out to be an undersized pervert with a broken blade and a talking pig! They are soon joined by a jealous giant, a fussy fairy, and an immortal bandit pining over his lost love. Can these people really be the legendary heroes she's looking for?
Having saved the kingdom of Liones from the Holy Knights, Elizabeth and the Seven Deadly Sins enjoy some well-earned downtime before heading off to their next adventure. Ban and Meliodas have a bout, settling an unresolved score and attracting a large crowd in the process. King and Diane enjoy a date together, Merlin tries waitressing at the Boar Hat while Gowther makes a new friend in town, and Hawk sends everyone on a wild pig chase! All the while, their defeated enemies are slowly recovering their strength, promising to make a lot more trouble for everyone in the not-so-distant future...

Gash and Kiyomaro must begin a journey that will take them into the demon realm to confront the mysteries of Gash's past.

He's trapped in limbo with the mad magic scientist who wants to be his partner and an army of Vulcan robot lookalikes. Dr. M2 sends a robot to pretend to befriend Gash, keeping him away from Kiyomaro until M2 can abscond with the teen genius to the future. In the end, it comes down to saving the world with a little help from their friends...
