I flew less than an hour on the back of a dragon.

The view spread beneath the eyes was more or less forests and mountains, but it was quite a fresh landscape with rare sights of something like a sub-tribal settlement at that point.

But on the other hand, I also realized that keeping this long time spanning the back of a dragon is quite harsh in a reality that is not the world of dreams.

The point is, I have to sit on something that doesn't make me feel comfortable, so my ass hurts.

I regretted that I should have at least laid a blanket or so.

Eventually, when Ildola stepped down in front of the ruins, Cyril, coming down from its back, also seemed to care by scraping her ass tightly.

The other three were kelloggy, so I'm a little jealous of Aura again.

I went to Cyril, a member and only one of us.

Cyril, I really wanted to learn how to treat Aura.

William, I totally agree.

That's what Cyril and I said, and we shook hands disappointingly.

And gently hug each other to be sure of their friendship.

It was the birth of an Aura Unusable Alliance.

"What, those two, why did you suddenly hug each other?

"Uh, I think I had some empathy. But I'm jealous..."

"Do you also have a bonus that says you can't use Aura? Shit, it was wet."

Satsuki and Aura said something when they saw this one, but decided not to care.

Well, aside from that.

That's how we got to the ruins.

It was a bush where tall grass grew on a parchment, and the ruins were tucked in securely so that they could be covered by trees, tsuru plants, etc.

The ruins are an undecorated stone building, the size from the outside is about the size of a grand aristocratic mansion.

But when I saw it, it was one story, and the grass was covered on top of it.

It was a strange building.

I don't see any entrances and doors, or anything that looks like windows.

Only the top stone walls shaped the exterior of the building.

When I see it, Mi puts her arms together and makes a difficult face.

"This is a labyrinth-shaped ruin? I've never seen anything like it before."

"Probably so. I don't think it was a home or some kind of everyday facility."

I agree with Mi.

Today, ruins of the ancient magical civilization era are found all over the world by the activities of adventurers, but such ancient ruins fall into two broad categories.

One is a residential and daily facility-type ruin.

This is what the people of the Magic Civilization Era lived in, or some kind of everyday use purpose facility such as the bureau, library, etc., is seen to have remained until this world without decay as it is.

In the case of these sites, for example, if it is a residence, there is a living room, there is a bedroom, there is a toilet, there is a kitchen, etc., so that the function as a residence is built with a glimpse.

Even such residential and day-to-day facility-type ruins are of little value as ruins because there are few precious items that can be found if explored that are not available in modern times.

Ancient spellbooks (spellbooks), scrolls (scrolls), and other fine magic items are often found in these ruins.

On the other hand, however, it has also been rarely discovered that such a functionality of everyday use is a site entirely invisible, and such buildings are called "labyrinth-shaped" ruins.

In a nutshell, this means a labyrinth like the one explored by adventurers from the beginning - that is, a building built to function as a "dungeon".

There are treasures in the deepest part of the world, and by the time we get to them, there are many obstacles... and so on.

It is not clear in modern times how such "labyrinthine" ruins could have been made.

The most powerful theory is the "rich man made it on the road" theory, and I also find this theory the most convincing.

But in any case.

We had one big problem in front of the ruins.

"But this ruin, where does it come from?

Satsuki spoke such frank questions as he looked far-flung at the appearance of the ruins.

Yes, that's exactly it.

Even though it's a building, I don't see a door or anything like that.

If you insist...

"After all, is it 'that'?

"Well, think about it normally. I guess so"

Look at what Mi points at, and I nod.

Ahead, pointed by the bandit (sheaf) girl, were two stone statues, a pedestal, and a stone tablet.

And they are gathered in front of the ruins, and they are laid in sight.

"It could be a trap. Mi will be ahead of you, so I'll be right back."

That's what Mi said and headed that way carefully.

He slowly snuck up and moved right in front of the stone statue, looking carefully into the vicinity of the stone statue and its surroundings, or making the cat's ears tingle.

Then Mi stared at the stone tablet behind the stone statue and then looked back at us.

"William, can you read this letter? I want you to come."

That's what they said, so I'll walk over to Mi.

And I saw the letters written on the stone tablet.

It was an ancient civilized letter.

Translate and read the text written there into modern language.

"─" Unparalleled Great Flaming Demon Sword, Sleeps Here. Only one set of connections is eligible to challenge this trial. Not a single person or a large number '? "

"Uh..."

When I hear my words, Mi thinks to chew on their contents.

And he looked up at me and asked me to do an answer match.

"The Flaming Devil's Sword is asleep in this ruin, which is fine, but the problem is after that, right? What do you think William is qualified to take this test - a 'set of connections'?... after all, the... is this it?

With that said, Mi points to the two stone statues right in front of her.

The two stone statues were both imitations of the human figure, but each had a different shape.

One, a musculoskeletal, ambitious man raised his sword.

One looks like a sweet woman holding hands to pray in front of her chest.

It clearly appeared to be a statue symbolizing the gender of man and woman.

And the expression 'a set of connections' of stone tablets.

Note that there is one pedestal on the left and right between the two stone statues, where nothing is placed.

It's like someone's just asking me to stand here.

"─ I guess. It would mean a dungeon that can only be challenged by one man and two women at a time. And most likely, this pedestal is the entrance to the dungeon. A teleporter who moves inside the ruins is a stone."

I cast one spell while answering Mi.

It's a magic magic spell.

When the spell is activated, my vision reflects magic.

Then the stone tablets and the two stone statues had no magic power, but the pedestals to the left and right of the stone statues both emitted red light indicating magic.

One more thing.

The appearance of the ruins themselves also brought together the whole red light.

This means that all the exterior walls of the ruins are magical.

Perhaps there is some powerful defensive magic stretched throughout the ruins.

According to adventures I've read in the past, these tricks seem to be common in the labyrinth-shaped ruins of this hand.

It would seem better to think that forced breakthroughs by means of fluoroscopic (see-through) spells such as internal breakthroughs or destroying the outer walls are impossible.

No, the truth is, I don't know where it actually is either, if I don't try it, but there's a cost to try it.

The clairvoyant (see-through) spell, for example, is quite painful to say that the cost ─ magic (mana) consumption was quite heavy and empty when I tried it.

My total amount of magic vegetables (mana capacity) is considerably longer than when I just became an adventurer, not to mention enough to release up to seven fireball (fireball) spells, but even now its clairvoyant (see-through) spells are enough to take roughly 10% of my magic vegetables (mana).

Still, I think it's worth using if you can expect results.

It's a thin prospect at a time when magic reactions from magic sensing (sense magic) are visible on the outer wall, and even if you look at the entrance trick, it's hard to believe that "the maker of this labyrinthine ruin" is not taking action around it.

... Well, I guess we should go here on a positive offense.

And with that in mind...

"And, by the way, William... I have one thing to worry about..."

Mi beside me said it was a little messy.

"Hmm, what?

"You know... this ruin, that only a pair of men and women can get in, William is sure...?

"Well, I guess so. I don't think you're gonna count Eileen as a man for anything."

Horribly, when I say this many people, there's not a single man at the party but me.

It is, nevertheless, an adventurer party of an extremely rare composition.

"So, I'm the other one... Mi is a little concerned about the meaning of 'connection'..."

"Hmm...?

I think of what the word "connection" means when Mi tells me to.

It makes more than one sense, but it would be natural to think of it here as referring to a "set of animal males and females".

"Are you saying that humans don't fit because they're not like animals at all? I find that hard to think about..."

"Yes, no, it's not. Look, don't you mean 'connected' and 'couple'?"

"... Oh, you mean that"

Mi pointed it out to me, I think so.

In other words, Mi fears that it is not just a man and a woman, but a man and a woman in a conjugal relationship, that they will not conform to the conditions.

"Well, if that's the case, you're lucky. Well, I'll have to give it a try."

"What are you trying to do!?"

Mi pins her tail and puffs her mouth.

Awwww, or it looks soothing.

…… No, I don't know if I can or shouldn't, but I think it would be the first time you and I would try to get on the pedestal... is something wrong?

"Ah...... Yes, no, it's nothing..."

Now I dye my face bright red, pat my cat ears down, shake my tail around and look embarrassed mi.

I'm not sure what it is, but all I could say for now was that it looks so adorable.
