This means I can get some cooperation here. If they've lived as long as Derieu, they should have a corresponding level of dungeon knowledge.
My luck is really holding out.
Well, with that settled, I quickly set up a teleport trap in the dungeon we had just taken over, connected it to my own dungeon, and brought Derieu over here.
"A-Aneue!!"
"Raie....!!"
That was ten minutes ago, when they were clinging to each other and crying.
This younger brother of Derieu is a Dungeon Master who builds orthodox dungeons. In the back, he had a solid residential area with an interior that looked like a grand mansion. I guess that part is the same everywhere.
However, there's one thing that feels off.
This current situation.
"Fumu. Lily, was it? What exactly can you do?"
"U-Um..."
Currently, we're gathered around a table centered on Derieu and Raie-kun, and for some reason, Lily is being interrogated.
Is she a sister-in-law from hell...?
"E-Elder Sister... Lily is a very good girl, so..."
"I wasn't asking you, Raie. I am asking this person Lily."
"A-Actually, I'm a Rank 7 adventurer."
She managed to react and answer.
Oh, Rank 7? That's pretty impressive.
"I didn't ask about that. In the first place, aren't adventurers the enemies of a Dungeon Master? What, were you planning to subjugate Raie?"
"N-No, nothing like that!! I was gathering information..."
Yes, yes, exactly. Information gathering is vital.
"...Anyway, Derieu, what exactly are you dissatisfied with?" I said.
"Watch your mouth!! You are not someone who can speak to her so casually!!"
Immediately, Anna-san snaps a reprimand at me.
"The one who should be quiet is you, Anna. Yuki is my husband."
"What!?"
Anna-san's eyes go wide at Derieu's words.
I mean, I guess it's a shock to find out the princess you finally reunited with is already taken.
"P-Princess... C-Could it be...?"
"Indeed. We share a bedchamber quite regularly. A child is only a matter of time."
"Y-You...!!"
"Calm yourself. We love each other. I won't have you meddling in our affairs, Anna."
"Gugh..."
Derieu instantly shuts down whatever Anna-san was about to say.
Well, it was something we had to say eventually, but what about Lily?
"E-Elder Sister. Like the older brother there said, what is so wrong with Lily?"
"First, she is weak. She cannot protect Raie like that."
"T-That's only because you were a Demon King, Elder Sister!!"
"What are you saying? I only arrived after Yuki and the others suppressed this place. My power had nothing to do with it."
"I-It couldn't be helped, right? His fighting force was abnormal."
"Naturally. He's the man who captured me without a scratch and brought me down. Though, it seems Yuki himself hardly moved a muscle."
This is totally the behavior of a difficult older sister.
Lily has tears welling up in her eyes, looking like she's about to burst.
Seraria finally felt bad for her and spoke up.
"Derieu, calm down. Your brother chose the person he loves for himself. Even Anna-san lacks the strength, don't they? Your dissatisfaction is just that you hate your brother being taken by a girl you don't know. Am I wrong?"
"Nu... gugugu..."
"Lily-san, please wipe your tears. Our Derieu has caused you trouble."
Ratz followed up immediately to support her.
"Sob... Is it really okay? For me to be Raie-sama's wife?"
"We don't mind at all. In fact, if we opposed it, would that really make you stop loving him?"
"No!! I could never stop loving him!!"
"Exactly. I feel the same way. There's no way Derieu could ever leave her husband either. Right, Derieu?"
"Of course!! As if I'd ever leave him!!"
"So, are you still going to reject Lily?"
"T-That's, well..."
So in the end, it's just sisterly jealousy... She really is acting like a nagging older sister.
"Well, if you don't know her, you should just get along from now on. Lily, I know it's tough, but could you please try not to hate this stubborn Derieu?"
"Yes! I have heard much of Raie-sama's sister. That she was a kind and wise person. Even now, she showed the kindness of worrying for Raie-sama. I will do my absolute best to be recognized by Derieu-sama!!"
Lily answered clearly and brightly.
Oh, she's a pretty solid girl.
"A pleasant girl. I think she's quite suitable as a wife. What do you think, Derieu?"
"...Well, I suppose I could acknowledge her. But there are still many points to observe."
"...You're really weird about your brother complex."
"I don't want to hear that from Seraria, who has a sister complex!"
Yeah, I have to agree with that one.
Aslin is having fun, but Filia is getting dizzy, so I wish they'd stop the "cuddling and rolling around" for a bit.
"Then, it is fine, right, Elder Sister!? For Lily to become a concubine!?"
"...Very well."
"Thank goodness. I'm so happy for you, Lily!!"
"Thank you!! Anna-san!!"
A splendid happy ending.
Of course, from here on out there will probably be a lot of "difficult older sister" harassment from Derieu.
But with these three, I'm sure they can overcome it.
"Now then, the marriage talks are settled."
"Isn't that a good story?"
"Yes. Though it does not compare to the story of my husband and me."
"...Shall we head back soon?"
"Yeah, let's."
With that, we stood up to leave.
Qual, acting as a guard, had been standing by the entrance the whole time.
"Everyone, thank you very much. Please, we will invite you when the ceremony is held."
"Ah, yes, please do."
Everyone else nodded in agreement as well, and then left the room—
"AS IF WE'RE LEAVING YET!!"
"""!!?"""
Everyone was startled.
Hey, hey, did you all completely forget why we're here?
"Ohh, so Yuki noticed as well!?"
"Ah, so Derieu understood too!?"
Phew. It seems not everyone was swept away by the mood. Derieu has a brother complex, but she's still sharp when it matters.
"That woman is simply not suitable!!"
POINT.
Derieu points a finger straight at Lily.
...Ack, I'm getting dizzy. She's hopeless.
It seems when it involves her brother, she can't think properly.
"You idiot!! We're moving on to the dungeon discussion!!"
"""Ah."""
My wives are hopeless.
Is talking about marriage really so fun that you forget everything else!?
"And, Raie-kun!!"
"Y-Yes!!"
"Your control is being stolen. Don't just try to send us home casually while forgetting that."
"Ah."
"...For now, I've heard that you are a Dungeon Master. We came to this dungeon because we had several objectives and thought a Master might be here."
"Yes."
"I'd like to talk about that now... Is that alright?"
"...I am so sorry."
...There better be some useful information here. Right?
I mean, he's been a Dungeon Master for 200 years... My labor hours for today weren't a waste, right?
With those thoughts in mind, we finally got down to business.
