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? Source:

The struggle for power where holy knights tap into demonic powers to help overthrow a kingdom while the heroes of the story are labeled as sinners and bandits. 

The animations are pretty solid, the characters are all pretty goofy and the story is told at a good pace.

The backstories are interesting and it’s fun to see how all the characters have crossed paths before, nothing feels like an afterthought.

All the ‘sinners’ in the story have received their punishment due to activities that were out of their control but have fully embraced the role they’ve been put in.

The little love triangles don’t get pushed too hard which then only adds a little bit more character to an already goofy cast.

The only issue that I personally have with this cast is how crazy overpowered Meliodas can be. Even in the moments where things aren’t going his way, he’ll still come out of it looking like a champ.
