― ― Ochanomizu Dungeon, 16th floor.

"Ah, speaking of which, do you know any monsters today? Masaki-san, I never knew such a monster."

"No, I don't know. It's not Needle Mouse, it's not Diving Mouse, it's not Gufu... Was there any other rat-shaped monster?

"I don't know. I've never even heard of it."

"After all... the theory of the back dungeon is getting stronger."

"Yeah, that sucks."

"Hey, miss! Did you teach a new rat-type monster class at school?

The five roads in conversation with the right castle turned toward the morning mist.

The World Explorers Association (WSA) is the fastest way for Japan Explorers High School to gather the latest information on the dungeon from around the world. Among them, it was customary to treat what was deemed important immediately as a lesson regardless of the grade.

For that reason, it was unlikely that even the Five Paths had information that they had not yet heard.

"No, I take zoology, but I've never heard of it. Sorry, I can't help you."

"I knew it... no, why is Miss depressed? We don't even know what a pro is, so you don't have to apologize."

"Yes, yes. I'm sorry."

I think the fifth way is fumu.

His known rat-shaped monster, Needle Mouse, is a monster like a halibut that covers its entire body with thin needles. They launch a nasty mid-range attack to fly the needle, but the body is surprisingly weak and classified as Grade Five at the bottom.

The other "Dive Mouse" is a monster digging into the shallow ground. It is very similar to a mole, and the nose part of the face is very stiff, causing an ambush burst. The rank is weak enough to easily defeat even members here in the fourth rank.

And the mouse monster I just fought.

There was no distinctive personality, but it was a monster with a high overall level. Speed, Defense, Attack, Collaboration, all at high levels.

I can guess from the color of my eyes that it was a Grade 3 monster, but the Five Paths were alert to the fact that they had the same Grade 3 talents struggling and were consuming more health than expected.

Well, it would be reasonable to call it a new species.

The five roads muttered small.

The right castle picks up the murmur and asks questions.

"It's called a back dungeon, so I wonder if there are a lot of new monsters?

"Well, I don't know. I don't know because I've never heard of it before."

"Well, then, it seems better to proceed on that assumption. New species are dangerous because they can't study beforehand."

"Right castle, that's a good idea. I miss being a runaway kid in the old Yancha."

"No, please stop! I was just a Tengu in Chariot! Please don't really go through the past."

"Haha, it's a joke."

As the other Explorers sat back and took a break from the dungeon's rugged walls to calm their breath, only the voice of the right castle and the five roads echoed loudly.

The castle was originally an attack-type genius, and it still had plenty of room for strength, as it also trained like an athlete.

The Five Ways were still confident in their health. The reason for this was quite different from the right castle, and the reason for having a second-class talent was great.

Explorers with second class talent are said to be nearly twice as physically capable as Explorers with third class talent.

All the Explorers who participate in this raid, except the Five Paths, have talents of three or less grades, so the difference in strength will appear as realistically as in these critical situations.

Everyone else was beginning to notice the fact.

The Five Ways knew about it, so I planned to stay here until everyone was well.

Hmm?

But the dungeon didn't wait.

The Five Paths detected disturbing movements with Commander's skill "Five Senses in tune".

The companion with whom the Five Paths were currently in tune was Numata Makoto, a veteran.

Her five senses were several times better than other Explorers, and she was being investigated after the battle to see what was going on ahead.

She captured such a disturbing movement, and the five senses were flowing into the head of the five ways.

(Narcotics, don't push it. Pull once)

(Yes, Mr. Godo)

The Five Paths used their "Command Transmission" skills to immediately turn back to Numata, giving instructions.

Then Numata turned her heel to turn back.

(Narcotics! Run faster!

(We're doing everything we can!

(All right! Let's just get out of here! I'll take care of the rest)

(Yes!)

From the tip of the main road, a swarm of green furry rat-shaped monsters began to attack the scorning Numata fields with sharp eyes in the darkness.

Numata has a section that specializes in five senses and speedy veterans, and even if he had a third-grade talent called "Bandit Leader", he was only as strong as a fourth-grade talent.

There's no way she's going to fight a pack of Grade 3 monsters alone.

"The break was over! Stand up now for more than a Level 3 Explorer! Numata's bringing the herd!

Nearly twenty fellow Explorers stood up at the call of the Five Ways.

Immediately regroup and assemble weapons to suit each combat style.

In the meantime, the unsuitable Explorers and students took the position of solidifying on the other side of the road and providing support from afar so as not to disturb them.

"At the same time as Count 1, fire if you have Ranged, Medium Range Attacks! Ready?"

"" "" Yes!

The Five Ways are always in tune with the five senses of Numata and measure the best timing.

In the meantime, I will give instructions to Numata, who will escape here in "Command Transmission."

(Snackclothes, the moment you get in here, crouch down and slide in. Understood?

(Yes!)

After issuing instructions, the Five Ways again measure the timing.

"3... 2... 1! It was here!"

At that moment, Numata appeared from the end of the main road, which was dark.

As soon as she heard the call of the Five Ways, she slipped into this belly-filled space.

There were several shiny arrows and magic bullets passing right over her head.

"Chewie!?

"Chu!?

"Chitchui!?

In a complete ambush, several monsters were pierced by arrows and magic bullets at the head of the herd.

Without needing to confirm it, the Fifth Path gives the next instruction.

"Algal rock! Aso!

"I know... 'Induction'!

"Me too!" Induction "!

"Hmm!? You're late!" Induction "!

The three Shields on this raid, Algae, Aso, and Tsukiki activated their Induction skills to attract the Monster's attention.

"Next up was the lady!

"Ha, yes!

Therefore, the Five Ways nominates Aika Asami, who has the potential.

The morning fog seemed to have already finished concentrating and used the unique ability "Weapon Enhancement (Weapon Doping)" to the right castle standing next to it.

After that, it was a battle of professional explorers.

Fully master the enemy's movements and gaze, and split the monsters in units as directed by Shield and the Five Ways.

The avant-garde attackers attacked there, decreasing the number little by little.

Magicians and archers consumed an auxiliary amount, and in this battle, they succeeded in reducing their wear and tear than in earlier battles.

Blushing up from bitter experience.

The process was adaptive enough to make students and other explorers roar.

They get used to the dungeons that brought about this transformation.

No, I'm used to it.

Still, they even seek an exit and push through the dungeon.
