Diane vs. Friesia

Diane vs. Friesia was a battle fought between Diane of the Seven Deadly Sins and the Holy Knight Friesia.

Prologue
While Meliodas was being treated by Dr. Dana, Friesia finds the group through one of his insects and decides to launch the first offensive and kill them. Diane engages Friesia in combat to protect her captain.

Battle
Friesia controls swarms of insects and makes them spray highly destructive and corrosive poison to kill the Deadly Sins along with the rest of the village. Though being afraid of insects, Diane, saying that if it was for helping her captain, it was nothing, overcomes her fears and rises the ground in the form of pillars to crush the insects. After completely wiping out the poison bugs, she dashes towards the Baste Dungeon to search and defeat Friesia. The battle is intervened into by Ruin who hypnotizes Diane and Meliodas, causing them to fight each other. Elizabeth finally breaks the illusions, thus releasing Diane from them. Friesia is then utterly crushed and defeated by Diane.

Aftermath
After defeating Ruin and Friesia, Meliodas and Diane enter the Baste Dungeon and encounter the fleeing Cenette who screams for help, as she was scared of Ban, who had just killed Jude. Ban then appears behind her and his and meet after ten years. Their greet each other by high fives and begin arm wrestling, which destroys the whole dungeon.
