"Fu ..."
Four of us, led by Sister-san, proceed along the aisle beside the waterway.
The stone tunnel was very dark and filled with moist, lukewarm air.
In addition, the odor rising from the sewage is quite strong.
Although the effect of Sanctuary prevents miasma and toxins, it is still a rather harsh environment.
"Will it be fine as long as we go to the place where it is marked in red?"
"Yes. It is said that it is the deepest part of the underground waterway. However, it is quite a distance, so it would be better to camp on the way."
"It's about time it gets dark outside."
Rouga-san takes out his pocket watch and mutters.
After walking 30 minutes further down the passage.
The passage suddenly widened and the field of view widened at once.
Apparently, this is the point where the sewage in the town merges.
We are breathing in a spacious space like an underground lake.
"It sure is wide!"
"This is just right. Let's rest here for today."
"Yes! My legs are about to reach the limit as well..."
"Mu ...! There's something, be careful!"
I felt a strange sign around me, albeit slightly.
This is not a kind of small animal such as a mouse or a bat.
When I alert everyone, I immediately pull out my sword and take a stance.
"It's here!"
"Tsk, it's from below!"
Five ghouls suddenly jumped out of the sewage.
It seems that they were hiding in the bottom of the water until we passed here.
It has become troublesome!
I cut off the ghoul's head and immediately kicked it.
Clean Hit (TL: MC says it in English).
The ghoul, which received a strong blow from the kick, loses it's balance and falls into the sewage.
Nino-san bows lightly while saying something blunt.
Speaking of Ninjas, they are Touhou warrior who are good at stealth behavior.
I've heard the name, but it's the first time I've seen the real thing.

"As expected, you'll get tired..."
Sister-san stops and wipes the sweat floating on her forehead.
Her breathing is rough and she looks very tired.
Is it about half a day since we entered the underground waterway?
Even though we take breaks from time to time, we still will become tired.
Even though they are small monsters such as bats and mice, there have already been several battles with them.
"Are you okay? Your complexion does not look good."
"I'm a little tired ..."
"From here on, I'll take the lead. Please lend me the lamp and the map."
With that said, Nino-san takes the luggage from Sister-san.
As expected of a B-rank adventurer.
Despite having a smaller and more delicate physique than Sister-san, she had a much better complexion.
However, it feels awkward to let only girls carry the luggage.
"Shall I take a little too?"
"Nope, it's fine. I have trained for this."
"No, but..."
"You should do your best to maintain the Sanctuary, because the miasma is getting stronger and stronger."
Yare~ Yare~, I am left utterly helpless.

But what she is saying is reasonable.
As the groundwater channel progresses, the concentration of miasma increases, albeit little by little.
Though it's not at a level that is immediately harmful, maintaining the Sanctuary is important.

The ghoul, which received a strong blow from the kick, loses it's balance and falls into the sewage.
"Ohh!"
Rouga-san's Shield Bash exploded with a scream.
Of the remaining ghouls, three are blown away together.
Oh, great power!
The ghoul, which was slammed against the wall, fell into the sewage and got stuck.
Next, Nino-san uses a black dagger-like weapon to decapitate the remaining ghoul.
"Huh...! Did anyone get hurt?"
"Oh, thanks to Sieg, I'm safe. Thank you for warning me."
"...For the time being, thank you. It's true that you noticed it earlier than me, a Ninja."

I've heard the name, but it's the first time I've seen the real thing.
Her hair is black, and maybe Nino-san has Touhou blood.
"This much is not a big deal, because it's basic to detect signs."
"Is that so? I think it's pretty difficult to feel enemies in dark places."
"I think it's a high class technique."
Nino-san speaks in a clear tone.
Are~, is that so?
My neesan said that if you are a swordsman, you can fight even if you close your eyes.
"But... it's a little weird."
"Hmm?"
"When I worked in the church, I often subdue the undead, but... I've never seen something like this ambush."
Watching the fallen ghouls, Sister-san tilted her head.
She groans as she thinks, pressing her hand against her chin.
"The ghouls are basically very low in intelligence. It's even safe to say that they don't have it. Basically, what they do is walk around and prey on what they see. They can't do anything advanced like ambushing their prey and attack it all at once. "
"I see. That's certainly something to worry about."
"At first glance, it looks like any other ghoul...?"
Nino-san crouches down and looks at the Ghoul's face.
Then the surface of the sewage behind it suddenly rippled.
--Yurari.
A huge black shadow is reflected on the muddy bottom of the water.
"It's dangerous!!"

"Huh!?"
I immediately pushed Nino-san's body back.
Almost at the same time, the water surface splits and a huge skeleton appears.
Oi, oi, why is there something like this in the underground waterway...?
Twisted horns that hit the heavens, fangs that tear meat and crush bones, and claws that crush rocks.
This monster is--
"Dragon Zombie...!!"
All four of us shouted the name all at once.
