Ep 9. Dark Pulse

In The Seven Deadly Sins season 1 episode 9 titled Dark Pulse, the group continues their search for the remaining members of the Seven Deadly Sins. Their journey takes them to a town where the people seem to be behaving strangely. They soon discover that a dark force is manipulating the townspeople and using them for its own nefarious purposes.

As they investigate the town, the group splits up to cover more ground. Meanwhile, Meliodas and Elizabeth come across a young girl who is being attacked by a group of strange creatures. Using his demonic powers, Meliodas quickly dispatches the creatures and saves the girl. She tells them that her father, a local scientist, had been conducting experiments on the townspeople in secret. These experiments had somehow awakened a dark force that was now controlling the minds of the townspeople.

In another part of the town, Diane and King come across a group of children who are being controlled by the same dark force. King recognizes the force as being similar to the one that destroyed his own kingdom years ago. However, he is hesitant to confront it as he still harbors feelings of guilt over his past failures.

Meanwhile, Ban and Gowther discover that the dark force is being controlled by a powerful demon who has taken over the town's water supply. Ban decides to confront the demon on his own, despite being warned by the others that he may not be powerful enough to defeat it.

As the group comes back together, they realize that they must work together to defeat the demon and save the town. With Ban taking on the demon directly, the rest of the group devises a plan to cut off the demon's source of power by destroying the water supply. With the demon weakened, Ban is finally able to defeat it and restore peace to the town.

However, the victory is bitter-sweet as King realizes that he still has much to make up for in terms of his past failures. The group continues their journey, with King vowing to use his powers to make amends for his past mistakes.

Overall, The Seven Deadly Sins season 1 episode 9 is an action-packed episode that explores the internal struggles of the main characters while also providing plenty of supernatural thrills.
