In the final layer of the ruins' dungeon, Yoko and White Ya were confronted by the demon Citries.
"The devil... you mean the devil? Don't play witch mountain."
"Oh, I'm not playing witch mountain games."
"There can't be a demon with a foul magic like the Lord!! Lord, aren't you the Demon King?
"Mm-hmm. Actually, it was (...) (...), but my husband erased the protection of the Evil God, so now I'm really, just a demon"
"What?"
"Duh, what do you mean?
"Well, quick story, this dungeon lass boss is the demon king who lost his power."
"... Does the Lord know about this?
"Are you telling me that I was the Demon King? Maybe, I don't think so. 'Cause until the moment you tame, they seemed to think I was a demon."
"Lord, you didn't come to mind when they told you that you were a demon but to the extent of a demon?
When I heard what this yoko said, Citrie laughed.
"You say funny things. Isn't it a good thing that you're the devil in front of him? Because it's like erasing the protection of the Evil God."
"Hmmm...... well, thats right"
"It makes sense!
Yoko and White Asia have convinced themselves of Citrie's words.
"So, as far as I can tell, you guys know your husband, right?
"I don't know you, etc."
"We're Hart's wife!
"Oh really?! Well, thank you very much for coming."
Citrie bows her head respectfully.
"Lord, I call the Lord my husband... but I'm not married"
"Yeah, not yet. But I have been tamed by my husband. My husband and I are bound by a stronger bond than the uncertainty of marriage."
"Hmm. After all, Lord, you don't understand"
"Hmm... what does that mean?
"That's right. Fight us and let me know if your lord wins."
"You two, you want to fight?
"Really! If I defeat you, Hart will reward you."
"Well!"
Suddenly the look on Citrie's face became brighter.
"So on the contrary, if I knock you both out, I'll be the one your husband will praise!?"
"Well, I don't know..."
"It's okay. I'm sure your husband will praise me."
"Are you willing to beat us?"
"Me and Yoko are so strong. No matter how many demon kings you deal with, you can't lose!!"
That said, they solved the humanization and went back to who they were.
A giant nine-tailed haunted fox and a bright white dragon stare at the citrie.
"Ho, are you Kyou Fox and White Dragon? That's also convincing to be confident. But..."
Citrie also freed her powers.
"I'm a former demon king, too. I don't think it's going to be that easy."
The enchantment of the Evil God disappeared and the magic that Hart replenished in an attempt to make up for the lost power had made Citri a few times stronger than he had been.
"Damn, the Demon King is a hell of a force."
"So, but you can't lose! Hurt's reward awaits!
"I know. Let's go, White!
"Yes."
The battle of those who sit at the top of this world has now begun.
