Merlin and her carefully guarded secret is said to be revealed in the next chapters of the Japanese manga series "Nanatsu no Taizai."

In Chapter 190, everyone was surprised when Merlin reappeared to help the people escape Fraudrin's trap. The last time she was seen, she was not in good condition. Due to Galand's decree, she was petrified.

Merlin arrived at the nick of time though, just when Fraudrin was about to turn everyone into demons. With his power, he trapped the humans inside a sphere. When it hatches, they would turn into something vile and terrifying.

As per Manga Sail, the drawings for the chapter looked scary enough, as the people awaited their fates. Even Jericho and Zeal, Guila's younger sibling, were trapped inside.

Although the Sin members tried their best to stop Fraudrin's evil plans, they had a very difficult time succeeding. Ban's technique did not work. Gilfrost attempted to teleport Gilthunder, but time was running out. Gustaf, Jericho's brother, tried to freeze the egg to stop the process, but his powers soon fizzled out.

Luckily, Merlin suddenly appeared. Her arrival shocked everyone, but it soon gave way to a celebration once she defeated Fraudrin. It is also important to note that another big revelation in the chapter is that Gilfrost is actually Vivian.

Meanwhile, Merlin's reappearance is said to signify that the time has come to reveal the true purpose of the Seven Deadly Sins. As per Yibada, speculations claim that the group was formed to destroy the Ten Commandments.

Merlin's true identity will also be revealed. She is said to be from a very powerful family, the Goddess clan, who co-founded the Sins with the Demons. This is reportedly why Merlin wants to kill the demons. The urge to rid the world of the foul creatures runs in her blood. Is it finally time to know more about the chosen seven?
