A dungeon. It is a mysterious space that stretches under the earth.

　It is a dangerous zone inhabited by countless magical beasts, but there is no end to the number of people who dare to challenge it.
　The precious materials collected from these monsters and the hidden treasures are what draws people to these dungeons.

　And those who earn money by exploring dungeons are called "adventurers".

　A few decades ago, they were treated like rogues, but nowadays, guilds exist as part of this respectable profession.





　Inside dungeons, there are not only magical beasts but also intelligent tribes that live there.

　They are called 'demonkind', and there are a wide range of species, including those that look exactly like humans and those that have a monstrous appearance.

　However, demons are not always friendly to humans.

　The king of the demon tribe - some of the demon kings plan to invade the earth.
　In fact, there are even countries that have been destroyed by demon kings.

　And those who explore dungeons to defeat the "evil demon king" are called "brave" as a sign of respect.





　They are adventurers who take on dungeons for personal gain or inquisitiveness.
　Others challenge dungeons with a sense of justice and honor.

　At first glance, they may seem incompatible, but in fact, it is not unusual for them to join forces with each other.

　I'm an example of that.

　I'm a veteran adventurer with fifteen years of experience in my career, and I'm currently employed by a brave party.
　The place to explore is the A-ranked dungeon 'The Thousand Year Corridor of the Abyss'.
　It is a difficult dungeon where the fearsome demon king is said to be sealed away.

　A brave man battles to crush the Demon King's ambitions.
　If I supported it, my rating as an adventurer would skyrocket.










Hey, wake up!　Luke!　Third-rate adventurer!
"Phew!

　A full-force kick to the gut, forcing me to be dragged out of my sleep.

　When I looked up while holding back the tremendous nausea, my eyes met with the brave Falcon in a form of anger.

''Gehoh, ghohoh ......... na, what is it, brave sir ......?''
"There's nothing going on here!　Look at this!

　The Falcon pointed to the end of the party, where the baggage of the brave party is put together. What the hell is wrong with that, .......

''...... Ah!　Hey, there's food!　They're devouring us!
It's your fault, you incompetent bastard!　There's not even half of it left because the demons ate it all up!

　I was just about to get up when the kick came again and I was kicked and rolled over mercilessly.

　As I hurriedly spit out the sand in my mouth, I asked for a more detailed explanation.

'Wait, wait a minute. The situation is totally ......
Warding stones!　Demon warder's stone!　I told you to put it in the middle of the camp before you go to bed!
Yeah, yeah, I put ...... on the website. ......
'I was out of position!　Our stuff was out of the wards because of you!

　If you ask me, the boundary stone is indeed lying in a completely different place than planned.

''Hey Julia!　How long do you think we'll have food!
'Even if we cut it down to the last minute, I don't know if we'll be able to get back to the ground after we clear the search target: ......
No, Luke!　What the hell is going on here?

　Falcon became even more verbal.
　The female swordsman, Julia, also glared at me with an accusing look.

'One wrong move and one of us could have been eaten, you bastard!

　Sorry about the escalation, but there was a crucial error in Falcon's perception.

'No, I put it right where I ordered it.
'Huh!　Is that an excuse?
Because, you see. There's a stone foundation in the middle of the camp.

　He points to the spot where the boundary stone was supposed to be placed.

''You always do this when I place a boundary stone, don't you?　Maybe the warding stone changed position after I put it there.

　I didn't misplace the boundary stones.
　There must be another reason.

''Come to think of it, hero-sama. As I recall, in the middle of the night, you said you were thirsty and went to your luggage. Didn't you kick something at that time?
'What?　Oh, ...... I don't know if there was ...... such a thing or not ......

　Falcon's voice gets quieter and quieter. Apparently it reminded me of last night.

　I placed the wardstone in the correct position and then went to sleep.
　After that, Falcon must have accidentally kicked it away and put it back in the proper position.

　In other words, he's responsible for the food being devoured. I'm innocent.

That's just the way it is, so don't blame others too much: ......
Paralyze!
What?

　Suddenly, a state magic flew from behind me and my whole body went numb and I couldn't move.

　It wasn't Falcon who shot the magic.
　It was the twin wizards who were part of the party.

''Totally. It doesn't matter who's to blame or what's wrong with them. What matters is what you do with it. Don't you think so too, sister?
"U...... yes, ...... yes, ...... yes.

　The white-haired white wizard is his sister, Bran, and the black-haired black wizard is his sister, Noir.

　They look alike in appearance, but their personalities are polar opposites.
　Bran is cheerful and dark-hearted, and Noir is a dark-hearted and easily swept away guy.

　Bran, as you can see, has an angry personality, but Noir's is not so much.
　Or rather, he was too weakly assertive and I wasn't sure if he was a good guy or a bad guy.

''Da-ka-ra. If we don't have enough food, we can just reduce our numbers.''
You're gonna send a wee-wee-wee-what to ......
Then the target of the cutoff is obvious, right? Right?　d*mn third-rate adventurer?

　He tried to complain with his paralyzed body, but all he got was a ridiculous look from them.

　And to make matters worse, even Falcon and Julia began to agree with it with good smiles.

''Oh!　Good idea, Bran!　Let's do it!
Yeah, maybe if we cut down one person, we can cut back and make it work!
A scullery maid who can only use the 【Restore】 skill won't make much difference even if she disappears after coming up here, right?

　While I was cowering under the effects of Paralise's magic, the Falcons quickly got ready to leave.

'At least it's a mercy. I'll leave you with this one, old man.

　A sword full of blade spills is thrown at my feet.
　It's a sword that looks like trash thrown away by other adventurers.

　And the brave party left me unable to move, and the four of us resumed the dungeon attack.

''U, woo-woo ......!

　I can't even scream well because of the paralise.

　They're right, I'm a third-rate, all-time E rank adventurer.
　Fifteen years of my career only means that I've been at the lowest level for the entire fifteen years.

　The only 'skill' that I can use is [Restoration].
　His reputation from the guild has always been at the bottom.

　The reason why I was hired by the brave party was because those guys asked the guild to introduce me to an adventurer who could be hired cheaply, even if it means dying, because they wanted a baggage carrier and scullery maid.

　The price is much cheaper than renting a horse.
　I was only worth about as much as a donkey for a hauler from the start.




　But still ...... still!
　I was betting on this dungeon attack!




　If you succeed in exploring the brave party!
　Believe me, your position in the Adventurer's Guild will be better!

　The end result of that is that they're forced to clean up the mess of a brave man's mistake and banished!
　And in the middle of a high-level dungeon!

　This is just too much, man!
