A Dungeon Battle...?

"A dungeon battle is…?"

"We invade each other's dungeons and, well, have a contest. The entrances would be connected to each other with space-time magic, we would send our troops into each other's dungeon, and the first to touch the Dungeon Core wins. Simple right?"

Setting the space-time magic aside, the rules certainly were simple.

However, the 'Imperial Capital's well-established dungeon [White Labyrinth]' and this 'Beginner-friendly dungeon where nothing but goblins appear [Ordinary Cave](There is a Dungeon Core inspection tour)' are completely not worth comparing to each other. They were too different. There was below a single decimal point chance of winning.

"Oh, of course there will be handicaps. My dungeon's degree of difficulty is so high that no one has been able to conquer it in over one hundred years, it's an extra-large dungeon with several derived dungeons."

Of course, Haku-san had noticed that as well and added supplementing terms.

"… Right, I will lend you 100,000 DP to prepare. I will create a derived dungeon like the new [Ordinary Cave], and will similarly prepare using 100,000 DP. I'll install a dummy core there, so it would be your win if you touch it… So?"

"… DP can be loaned out?"

"It can. Since it's not an exaggeration to call dungeon battles contests… well, right, if you win, it's fine to not repay the 100,000 DP. In addition, I'll transfer another 100,000 DP as a prize."

It seemed to be quite the profitable condition.

"… Then, what if Haku-san wins?"

"The loaned 100,000 DP will be returned, in full… Ah, that doesn't mean anything unpleasant you know? You'll do it as an adventurer in my dungeon. I'll have you work until you earn back the 100,000 DP. You will swear to hand the responsibility of protecting Number 695-chan until your repayment ends. Isn't it normally impossible to have such favorable terms?"

They were favorable conditions indeed.

With the 100,000 DP I'd gain, I could make the dungeon how I like and could fortify.

However, I should remember.

Although one Goblin costs 20 DP, just 2 DP is returned when it is killed inside of the dungeon, so that's the rate of return. In other words, if for instance 100,000 DP was earned by working on single type of monster, that would be fifty thousand Goblins, or ten of the lowest ranked 100,000 DP Dragons. I wonder just how much time that would take?

… No, wait. That's not it. Would it even 'submit the DP' by killing monsters in the dungeon to begin with? Of course, by destroying valuable monsters, wouldn't the debt increase?

If so, it was the same thing even if I just aimed for items without even killing a single monster. For items, Haku-san may not accept it since she placed it using her DP.

At any rate, only Dungeon Cores and Dungeon Masters could truly earn DP.

"… Earning 100,000 DP as an adventurer, well, that's hard."

"Oh my, I didn't intend something like that. Then 100,000 DP worth of fruits of battle is fine."

"… I would PK as a monster? Don't veteran adventurers gather in [White Labyrinth]?"

"Fufu, there is also a derived dungeon for rookies you know?"

Haku-san giggled and smiled like she was enjoying this.

I really can't be negligent, this person… is a Dungeon Core huh.

"I understand. Then what is expended on you in the derived dungeon of the [White Labyrinth] will be yours and converted to DP, that's fine. If that's it, how about it?"

"I agree if that's the case, but… what merits are there for Haku-san?"

For example, if he found a [Scroll of Healing (100,000 DP)] and used it on himself, it would be achieved.

"It's more or less an excuse to circulate mana by using DP on adventurers, is my official stance. The best merit is… while you are trying to be an adventurer, Number 695-chan will be protected under the agreement you know? … I'll guarantee her safety by filling up the entrance and not letting anyone in, and look after her in the Imperial Capital… normally, that child wouldn't agree even if I said to."

I see. So if she can secure Rokuko's safety, that was enough of a merit.

"… Go on and accept it! This is a practical test to see if you can really protect Number 695-chan."

Though, it doesn't look like I can veto it.

 

＊ ＊ ＊

 

"So, Number 695-chan, we'll be having a dungeon battle."

"Eh— what's a dungeon battle, Number 89 Ane-sama?"

You didn't know!? Haku-san and I then explained it to Rokuko.

"Heeh, it sounds interesting."

"Well, DP is going to be wagered for this contest. I'll lend the DP this time."

"Eh— you can hand over DP!?"

You didn't know? I didn't learn until a little bit ago but there's a difference there, oi.

Come to think of it, I wonder how the DP will be handed over…?

"Umm, it's not unreasonable that Number 695-chan doesn't know, there wasn't a reason for her to. The method to hand over DP is… umm, ummm, k-kissing is needed you know? A kiss!"

"Is that so? Chloe-san."

"No, according to my memory, a handshake is enough."

When I asked the butler about it, she answered properly.

"… It's Number 695-chan's first time, and since 100,000 DP will be transferred, a kiss is needed so that it won't fail or leak. It's easy to fail on your first time, so the safest method should be better…?"

Such a flimsy excuse again…

"Guh— 100,000 DP!? I can't take that much!"

"It's just a loan you know? Besides, it's to prepare for the dungeon battle. Since the game is about smashing DP against each other, wouldn't it be boring if we used Number 695-chan's dungeon's current state of no DP? This is a handicap from me."

"U-uuu…"

"Since we'll return it if we're defeated, it's just a loan. Don't hesitate and just accept it. This way you'll be able to properly listen to Haku-san's way of doing things."

"… Uuu— I understand. Then I won't hesitate, itadakimasu, Number 89 Ane-sama."

Oh, come to think of it, doesn't [Don't hesitate and just accept it] count as an order? I haven't really been considering my absolute order rights until now huh. Furthermore, it looks like she's even purposely anxious to follow the order.

Ah, Haku-san did a thumbs up that Rokuko couldn't see. I wonder if that hand sign has the same meaning here?

"Number 89 Ane-sama, how should we exchange DP?"

"Close your eyes, open your mouth and stick out your tongue. Yes, good, good job. Leave the rest to me. Well than, itadakima—… I will transfer it."

… Just now, wasn't she about to say 'itadakimasu'?

Haku-san and Rokuko's tongue came into contact and glued together.

Haku-san tenderly embraced Rokuko's trembling body with her left arm, firmly drawing her head closer with her right hand so they wouldn't separate. Is it because it's her first time? She kept her eyes shut just as Haku-san said. She avoided touching anything sensitive, but she trembled and even her ears had turned red.

Though time seemed to move very slowly up till here, it seemed this was still the preparation phase.

Haku-san held the back of Rokuko's head with both hands. Something in their mouths moved… perhaps the DP was being poured?

Though Rokuko was surprised and almost moved away, the moment Haku-san saw the light connecting their tongues, she was immediately held by both of Haku-san's arms.

After that, it took around ten minuted for the DP to be handed over.

When they finally separated, their saliva made a bridge between their tongues, snapping apart.

"… Puha, hah, hah…"

"Fuu…"

The two people who separated their mouths had contrasting faces.

While Rokuko was breathing roughly with closed eyes, Haku-san licked her lips in satisfaction.

However, both of them had flushed cheeks from ecstasy.

"… A little of it leaked, but I gave some extra as service."

"Hah, hah, t-thanks, vewy, mush, Number 89 Nee-sama… Hau."

"Ufufu, did you first DP transfer surprise you? Good, since you were held so so long, you should take a rest."

Haku-san gave another thumbs-up that Rokuko couldn't see… Apparently, it also meant 'good job' in this world.

I confirmed how much DP Haku-san deposited into Rokuko's body.

… 114,032 DP. It looks like the DP succeeded after all.

It should have been around 3500 when they started so… oi, she gave the amount of DP we got from exterminating those bandits with great pains as a service? Just what is Haku-san doing for income?

"Ah, right Kehma-san. If you don't make any preparations and [Lose, returning the 100000 DP as is]… something like that is, of course, unacceptable you know? I won't let you use the loaned DP to repay the loan."

… Oops, she hit the nail on the head.

If she didn't say that it would have been nothing but profit.
