While Meliodas and Escanor searched the castle of Edinburgh in search of the Vampire Clan, Meliodas ends up separating himself in the middle of his motivating speech to Escanor. There, it is found by Ren and Gelda, with the former believing him to be the individual who sealed them 3,000 years ago.
Battle[]
Searching revenge for their imprisonment, Ren uses her speed to attack Meliodas from the back, but he dodges her sword. Meliodas responses with a slash from Lostvayne that Ren also dodges. After a exchange of swords, Ren is pushed back while Meliodas's helmet is cut in half revealing his face. Ren says that despite his personality change she will never forget his face, proceeding to give a strong assault that makes Meliodas go back. While she says that they were not defeated by his power since he decided to seal them, Meliodas intercepts his back attacks asking for who is she confusing him. Ren reveals that she believes he is Zeldris, surprising Meliodas.
There, Ren is suddenly burned down by Gelda, who already known that Meliodas was not Zeldris. Instead of fight, Gelda ask Meliodas to kill her.
Aftermath[]
As Gelda reveals her story to Meliodas and ask him to end her life, feeling unable to live in a world without her beloved Zeldris, Meliodas seemingly granted her wish and killed the vampire in a massive burst, that resulted in the destruction of Edinburgh, but Meliodas actually sealed her again.
