Hello!
The Seven Deadly Sins are a group of knights who live in the Britannia region.
Ref: https://www.tecmundo.com.br/minha-serie/220321-the-seven-deadly-sins-anime-vai-ter-6-temporada.htm
This group broke up after being accused of trying to overthrow the Kingdom of Liones. Their supposed defeat came at the hands of the Holy Knights, but rumors that they were still alive continued to persist. Ten years later, the Holy Knights staged a coup d'état and captured the King, becoming the new tyrannical rulers of the Kingdom.
The third princess, Elizabeth, began a journey to find the Seven Deadly Sins in order to regain her Kingdom again.
