The Seven Deadly Sins have finally neutralized the Ten Commandments and it may be soon that new opponents will be introduced in the series.
In "Nanatsu no Taizai" chapter 195, the battle between Meliodas and Fraudrin continued with the latter getting outmatched by the revitalized captain of the Sins. Upon merging with his clone, Meliodas gained a magic power of 60,000, almost half as much of Fraudrin's 31,000. With his back on the ropes, the demon decided to self-destruct, planning to kill every human in the Kingdom of Leones.
Just when he was about to explode, Griamore rushed over to Fraudrin and used his magical sphere to prevent the destruction of the country. For some odd reason, Fraudrin was moved by this and told the kid that he will not proceed with his plan and he is giving Meliodas the green light to kill him, to which the latter obliged. Everyone was shocked to see Meliodas kill the demon without hesitation as he was known for his kind-hearted nature.
Fans over at Manga Sail believe the Demon King inside Meliodas is starting to take over and every time he gets in serious danger, the curse will just keep on getting worse. Fans are also not convinced that Estarrossa and Zeldris were killed by Escanor, as they seem to share a deep history with Meliodas, which is yet to be told.
Fans also believe it would not be long before the series enters a new arc and introduce new opponents. Some suggest that the Goddess clan is not as pure as their name implies. It is worth noting that the Goddess Nerobasta apologized to Derrierie for killing every member of the demon clan despite agreeing to a truce. Also, the entity that ordered Ban to kill Meliodas is hinted to be from the said clan as well.
It was also revealed that the Goddess clan consists of four strong leaders called "Four Archangels" and even the Ten Commandments are wary of them. For those who have yet to read the chapter, it is now available over at Manga Mint. Here is a video review of "Nanatsu no Taizai" chapter 195.
