Diane vs. Friesia

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

Prologue
When Meliodas was being cured by Dr. Dana, Friesia decided to attack Dalmary Town and defeat the Seven Deadly Sins. In order to protect her captain, Diane decides to engage in combat with Friesia even though she hates bugs.

Battle
Friesia begins the battle by controlling swarms of bugs with his technique, Rain Capriccio. Although Diane is afraid of them, she overcomes her fears and manipulates the ground and crushes the insects. After completely wiping out the poison bugs, she dashes towards the Baste Dungeon to search and defeat Friesia. The battle is later intervened by Ruin who hypnotizes Diane and Meliodas, and cause them to engage in a battle. Elizabeth finally breaks the illusions and Diane regains her composure. She later crushes Friesia entirely, possibly utilizing her superhuman strength.

Aftermath
Soon after that, Meliodas and Diane enters the Baste Dungeon and encounters Cenette who screams for help, as she was scared of Ban who had just killed Jude. Behind her, Ban shows up and reunites with Meliodas. They are so happy to meet again and begin arm wrestling, eventually destroying the whole Baste Dungeon.
