--Two weeks ago.

Next, Ochanomizu and Ochanomizu. The exit is on the right.

Tenjiro Noriji grabbed the hanging leather while being rocked loosely by the train.

Looks like he has an empty phone in one hand and is watching this month's household ledger app.

"Balance for the month: ¥105-" was displayed there. Looking at the poor numbers that are likely to arrive negative anymore, Tenji's face becomes even more steeper. When I scrolled the next page, I sighed loudly without worrying about the eyes.

A high school uniform with a grey line in a black fabric is the kind of garment that wears such a tenge, but what looks like a poor person doesn't seem to accurately represent the misery of the household.

"When this mid-sized raid is over, I wonder if I'll have to go to Mr. and Mrs. Taguchi's bakery next week to get discarded bread and eat it... hah, hijiki"

The sad words that murmured alone were wiped out by the noise of the train.

Tenge plans to participate in a medium-sized dungeon raid, which will be run by a prestigious guild.

In this era, people who make a living in the dungeon are called 'Explorers'.

It was a peaky profession, but it was a dream profession, because loans could not be arranged and large shopping basically could only be purchased in bulk. With the potential to become a billionaire, the popularity of many as heroes and heroes, surprisingly many young people tried to become explorers.

Of course Tenge is one of them.

The reason was that my parents were originally Explorers, but sometimes they were born with a few 'unique abilities' and were on their way to becoming Explorers.

Such a tenge sighed again.

(I have to set aside my sister's school travel expenses from now on, and I have to repay my debts. It costs me a lot of utilities and I don't have to cut down on food. This transportation is a painful expense. I've seen an organ sell expensively in a movie, but I wonder.... no, let's stop that. The Explorer's capital is his body. Hang in there!

The train stops at Ochanomizu Station, and Tenji gets off while thinking.

Go straight to the mouth of the sacred bridge and exit the ticket looking at the balance of the IC card that is being pulled in vain. As you go down the Awaji slope from there, you can see the brickwork below the elevation.

Once upon a time, there were secret restaurants and grocery stores beneath this elevation, but now there is a city that resembles a different downtown area.

One of the only 47 dungeons in the world appeared in the Ochanomizu. This was one of the big reasons.

Common name: Ochanomizu Dungeon.

The level, that is, the difficulty, is not so high, and is set as the second "fourth level" counting from the bottom.

Dungeon grades have been determined by the World Association of Explorers (WSA) by measuring the still unknown energy concentration of "MP atoms".

Dungeon grades include Grade 5, Grade 4, Grade 3, Grade 2, Grade 1, and Grade 0.

The Ochanomizu Dungeon is not so challenging, and even high school students who are not professional explorers like Tenge can easily enter if they apply in advance.

Having said that, Tenge is not just a student.

Japan Explorer High School. There is also a reason why I am enrolled in the only high school in Japan that trains explorers, and I can only apply for dungeons that are not dangerous like this one.

As long as you don't have an acquaintance of Explorers, you won't be able to get into high school so easily. Tenge had his parents as Explorers, and only the Explorer's helper was lucky.

"I'm not busy today... Is that a Chinese tourist organization? You bought so many explosions, you're rich."

The tenge sarcastically murmured down the Awaji slope so that no one could hear it. After descending the slope, there is a large intersection. Across the intersection, you can finally see the entrance to the Ochanomizu Dungeon.

Facilities are quite different from commercial facilities, but they are strictly surrounded by concrete walls and wire fences. Of course, there are many self-defense officers around to prevent the intrusion of outsiders and patrols.

Twenty-three years after the dungeon, only such a simple wall was built because the dungeon gate was too large to cover it neatly.

The dungeon gate, which is about 600 m tall and over 100 m wide, is made of obsidian black ore.

The door is slightly open enough to accommodate about 10 people in line, and there is a black oil film like ink inside the door. Through there you will arrive at the dungeon, but not many people have seen it with their own eyes. As long as I don't work as an Explorer, I hardly ever see him.

Tenge looks up at the huge black gate and slowly walks down the road.

The surroundings of the dungeon were redeveloped more than a decade ago, and many shops and facilities are now attractive tourist attractions.

The number of restaurants and restaurants was surprisingly small, and shops selling items and weapons were lined up. Of course, everything from items that are expensive enough to pop out to items that can be bought cheaply.

It's expensive after all.

Tenji found an expensive Western sword decorated in a showcase at a weapons store on the way, and began to gaze at it with eyes as if a child were toying.

The price tag says "Grade 3 Weapon: Spirit Sword ¥15,000,000 -".

When I looked at the price tag, Tenji calculates the cost of food by saying, "I know the cost of food for 1000 months...", and I was forced into reality.

The Tenji family lives with their sister in Sasatsuka.

They also have a debt of 70 million yen left by their parents who went missing in the dungeon six months ago, so they spend less on food and live in poverty together.

No matter how I scratched my feet, I couldn't afford to pay this amount for my current tenge.

"Hah, I'd like to buy this kind of weapon someday...."

To say so, Tenji can think of her sister's innocent smile in Tenjo Maharu.

My sister is two years younger than Tenge and is now in second grade. At a time of puberty and growth, I really wanted to feed you more meat and fish, but unfortunately I couldn't afford that.

Originally, I had a choice to go to the facility. However, the Tenjo brothers dared to refuse the choice in the past.

"Before my weapon... I want you to eat meat in the spring."

As a brother, I was above all a tenge who wanted my sister to grow up.

And that's when it happened.

"--Tenji!

I heard the voice of a woman who was used to hearing it from behind.

Even though I was accustomed to hearing it, I just became a friend of mine in the past month or so, and I had a strong impression of being a kind classmate to Tenji.

"Tenji! It's good to see you before we meet!

Even though I was a classmate, I said polite words, and yet my voice was full of vitality.

Tenge looked back in the direction of his voice and raised one hand halfway as he leaned down diagonally slightly embarrassed.

"Good morning. Asami san"

"Good morning! Thank you for introducing me to this opportunity today. It's thanks to Tenji that I just entered high school to experience Dungeon Raid."

"Yes, I would be grateful if Asami could work part-time with me with my luggage. But was it really good? If it were Asagi's unique abilities, I would normally pull him off as an assistant explorer."

"Even with luggage, it's worth the experience from the first year of high school."

After starting to walk side-by-side with the tenge, Aika slightly inflated her cheeks and pointed to the tip of the tenge.

Asagiri Aika.

She is a first-year student of the same Japanese Explorer High School as Tenji and, unlike Tenji, was born with the unique abilities of a winning team.

Chestnut Bob always lowers her creepy hair, but today it is unusual for her to tie her back head together because of the dungeon, and every time she walked, the ponytail swayed loosely from side to side.

In a class where each technique is elegant and everyone can speak kindly and politely, the popular morning mist cared about the tenge and decided to join the raid together this time.

Don't you ever come to Ochanomizu in such a morning fog? I walked along with the tenge stride while looking around as if it were rare.

Speaking of which, Asagi-san, you had an inner suit.

"Yes, when I told my parents I was going to the dungeon raid for the first time, they sent me a lot.... you're sweet to me."

The morning mist stained her cheeks with vermilion and smiled a little embarrassed.

She wore a uniform with a white line on a dark green fabric supplied by the school. I could see the blue fabric sticking to my skin from the neck. That's what Tenge calls an inner suit.

In the dungeon, there is no defensive Adamantite armor that is common in games, etc. Instead, the inner suit under the clothes appears as the only defensive gear.

Because wearing an inner suit has the effect of disabling more than a certain amount of attacks or aiding body movement, professional Explorers basically come in civilian clothes to challenge the dungeon.

Personal clothing is famous for being jersey, athletic, and fashionable.

(Even so, the blue fabric... was quite expensive. I want one day, too.)

Throughout her high school life and her behavior, Tenji decided to throw pure thoughts at her.

"I've always wondered, is Asami's house wealthy? Even an inner suit costs 100,000 yen, but that blue suit is probably a fourth-grade item worth 500,000 yen, right? Ah, sorry to interrogate you. If you don't want to answer, that's fine."

Maybe Tenge was a little jealous of her affluence.

For Tenji, who fills his stomach with bread ears and sprouts every month, he envied a morning mister who could give him an item for half a million yen.

"... it's too protective."

Her face was a little cloudy.

Looking next door, Tenji realized that the subject should not have been touched upon.

"Er... uh... Ah, Mr. Asagi, this is your first time carrying luggage, isn't it?

"Yes, it's my first time. This time, I'm going to look behind Tenji and learn from him."

"Well, then you have to work hard. That said, it's what I learned in high school, so I don't think I'm going to teach Mr. Asagi."

"Textbooks are often different from reality. If you'll excuse me, how many times has Tenji been here?

"I... don't know how many times I've dived the sub-dungeon. I've had seven main dungeons and five inner raids."

"Wow! Tenji is amazing after all. I'm already a veteran."

"Ahahaha... well, I'm carrying my luggage."

"Still, amazing things are amazing. Even though I'm the same age, I've never even been in a dungeon. That's why most of my other classmates have no experience."

She lowered herself and lifted the tenge often, but the tenge only sounded humble.

I just needed money to live, so I just lurked in the dungeon, and if it's true, I don't want to participate from those who don't have "Nature".

It takes about five minutes for the conversation to continue without other love.

They arrive at their destination.
