On the way to the walled city of Coland, the Seven Deadly Sins encountered a dimensional warp, which teleported them to the realm. Upon the arrival, Diane found that Hawk was missing. While the Seven Deadly Sins decided to split up and search, Merlin and Escanor stayed behind to find the way back to the original world.
Carrying Elaine into his arms, Ban called out to Hawk but he was nowhere to be seen.
Elaine: Where is Hawk? I'm so worried about him…
Ban: Don't be, Elaine. Master will be fine!
Elaine: Hmm, you're right.
Elaine: Someone might have hurt. Ban, let’s check it out.
Nodding at Elaine, Ban carried her and headed towards the sound source——a blossomy tree. Near the roots, there was a petty elf struggling as it was trapped by vines at the ankle.
Elaine: We gotta save him! Ban.
Ban put Elaine down on the ground, who crouched down and freed the elf from the vines. When she got back up on her feet, she lost balance.
Elaine became sickly pale and drowsy. Meanwhile, the freed elf came over to her immediately.
Elf: Thank you for saving me. What can I do to help her?
Ban: If you wanna help, tell me how to save Elaine!
Elf: There's a butterfly elf residing in the forest, who owns a magical sphere that might be able to save her.
Elf: The only concern is that the forest is surrounded by a poisonous swamp!
Ban: Really…!? Tell me where the elf is!
The elf told Ban the location of the forest. As soon as Ban got the info, he took Elaine to the said place right away. When they arrived at the said location, the foresting was nowhere to be seen.
Ban: Damn it...Where the heck is it!
The agitated yell from Ban drew an uninvited guest——a gigantic drooling predator.
Ban: Get out of my way——!
After putting Elaine to a safe spot, it only took Ban a few hits to put down the beast. To his surprise, the forest was revealed when the dead beast brought down an area of trees.
Ban: “Is this the place...of the elf?”
Ban: Hold on, Elaine.
The forest was isolated by a cloudy bubbling swamp. Dark purple miasma was released as the bubbles popped. Meabwhile, a fallen leaf was corroded into nothing as soon as it made contact with the swamp, displaying the extreme toxin it contained. At this moment, someone spoke.
???: Begone, resident of the strange world, or you'll be devoured by this swamp.
Yvette: I can enhance the connection with the sphere but with a cost. Will you do so if if takes your soul——
Ban: I’m willing to pay any price just to save Elaine!
Yvette: …Haha! This is my first time to meet someone like you who would say yes without hesitation…Alright. Let me help you.
Ban: Alright. Take my soul then.
To his surprise, Yvette burst into laughter.
Yvette: Why so serious? I was just messing with you. I don't eat souls anymore.
With a smile, Yvette raised the sphere, which began exuding soothing lime halo. The halo then wrapped Elaine up and diffused into her gradually, revitalizing her to awake.
Ban: How do you feel? Elaine…
Elaine: Did you save me? Thank you.
The lovers held each other tight again after a near-death experience, as if they would never be torn apart even by death.
They took a break and didn't resume the search until Elaine regained her strength…
