Seren Dungeon, the lowest level.
　In an unusual atmosphere, the 'thing that defiles purity', Dungeon Master Bicorn, was on the prowl.

　A few encounters, it's still a rare monster.

　A bicorn and a unicorn.
　Uni means 1, and bi means 2.
　A bicorn, as the name implies, is a two-horned monster that is the counterpart to a one-horned unicorn.

　The bicorn.

Repetition.

　He killed it instantly with
　All magic power was used up in an instant, and he recovered with a series of infinite recovery bullets.

　Dungeon masters can't take time to train and discipline; Repetition will kill them instantly.

　The longer it goes on, the less money other adventurers will earn, and if something goes wrong, the structure of the dungeon will be altered.

　Repetition is the best and only realistically possible option.

I'm done with this. That's it for this year's work.

　I mumble, recovering from my exhaustion.
　But apparently it wasn't over.

　The downed bicorn dropped, I thought it was the second bicorn horn Celeste uses, but it wasn't.

　It was a staircase.
　Seren's lowest level, a staircase appears there that leads further down.

　The stairs leading to the dungeon spirits.

...... You're a dungeon master, aren't you?

　I tweeted, but I'd be on guard for a moment.
　I packed the two pistols with all kinds of special ammunition, just in case anything goes wrong.

　I descend the stairs - the staircase disappears completely when I complete the descent.
　There is nothing there, a mysterious space of 'white'.

Are we together so far?

　The white space was a road. After following the path for a while, we came to an open, vast space.

　There was a monster (?) There was something that looked like that.

　She was a rather tall woman, about six feet tall or so.
　A beautiful woman with long hair and a cool atmosphere.
　There were glowing balls the size of softballs flying around her.
　It's like a planet flying around a star.

　The number of balls is seven, and each color is different.
　I'm sure it's a magic ball, judging by the way it glows and its strangely insubstantial appearance.

The only thing that can be said for this is that it's not a bad idea.　Or--

　The moment she opened her mouth, the woman held up her hand.
　Clear skin, fingers like white fish.

　A karma flame was released from those fingertips!

Of course!

　We ducked and ducked the flames that came flying in with a growl, and first of all, we shot the normal bullets and the tracker bullets of the small check.

　The normal bullet that flies straight, and the follow-up bullet that flies in the direction of the day after tomorrow but draws an arcing trajectory.

　I fired both straight and curved bullets at the same time.

　The woman held up her hand further, the blue magic ball became an ice shield to prevent the bullets.
　If it was an ice shield - and fired a flame round and a slashing round at the same time.

　It's not just a matter of time before you're able to get your hands on it.
　Quickly chase--.

''Guhaha!

　The impact came from right beside me, and I quickly jumped to the side, but I couldn't catch the impact and was blown away.

''Guaaaaaah!''

　A painful blow that scorched his entire body came in two stages.
　This is - an electric shock!

　I landed and took a turn, getting up quickly on my knees and hands.
　The balls that had been flying around the woman were buzzing and discharging where I was standing.

　The woman flew at me without a chance to breathe.
　It wasn't a ball of magic power, it was the person herself.

　I touched one of the magic balls and squeezed it.

''Zanjin sword, summon.''

　I thought I heard voices, but that wasn't the point.
　The woman slashed sharply with a sword whose ball of magic power had changed.
　I can't duck it in a hurry, I cross my arms and guard it.

''--!

　A strange phenomenon occurred.
　The sword didn't cut the sleeve of his jacket, but when it did, it ripped underneath his clothes and spurted out blood.

　The pain of a slash, a pain that burned the skin after a breath of delay.
　He kicked the ground and kept his distance while firing a series of normal bullets, startled.

　I look at the area where I was cut before recovering.
　The clothes are still innocuous, but the skin has been ripped open.

　A series of recovery rounds, closing the wound.

　The woman readies her sword and rushes further, her stance and speed are both quite good, she is a monster, but she is a master.

　The clothes that have not been ripped, the clothes that have not been ripped, the normal bullets are fired in succession, the scrap bullets are also fired afterwards.

　The woman who went straight while repelling the normal bullets flying at high speed with her sword, the scrap bullets that go limping along also try to repel with the sword, but...

"!!!
Too bad it's not a working one.

　The woman's sword, a super-slow speed scrap bullet that wouldn't break its own pace no matter what, didn't burst it.
　And as I guessed, it didn't even slash.

　A slashing sword, it certainly sounded like it.

　Her clothes were completely intact, but only her skin had been sliced open.
　It is a sword that can only slay humans - a sword that can only slay humans.

　I've figured that out - but.

''I don't think I'll be spending much time on it.

　Immediately after cutting me, the other magic balls became even more brilliant.
　There's something, I thought of it in my gut.
　Long term battle is not good, we have to finish it all at once.

　I fired a tiger's acceleration round at myself.

　Instantly, the world went still.

　I thinned out on the woman in the accelerated world and hit her with a cross counter as hard as I could.

　The woman is blown away, but the response is vague.
　The ball of magic power catching up with the blown up woman, the light of magic power swelled for a moment and became weaker than before.

''Defense?　Transfiguration?　Either way, should we do it then?

　The accelerated bullets were thirty seconds, I couldn't take the time.
　I rushed forward again, and this time I did it from the magic ball.

　The woman is indeed a monster that defends (...) this space.
　I'm the only one in this accelerated world who fought back.
　I'm not going to be able to get the best out of it.

　Avoiding the sword, at high speed - but while accelerating I could see it well, avoiding the attacks of the magic ball that was spinning behind me.

　Penetrating bullets were shot from close range into every ball of magic power.

　Within the accelerated world, the ball of magic power shattered almost at once.
　As the woman's expression grew stronger, I thrust the muzzle of my gun at her and topped it off with a regular bullet from zero distance.

''Fufu ...... a tough one. ......

　After the acceleration broke, he gathered up the air that had accumulated in his lungs and swept it out.

　I waited for the downed woman to slowly disappear.
　I kept my gun at the ready to respond to whatever happened, but it was unfounded.

　After the woman disappeared, what appeared there was a single bullet and a staircase that led further down.

　The stairs must be the path leading to the spirit's room, and that's what it was until now.
　Seren, the spirit of the Seren Dungeon, Seren.
　That's what's down here.

'I mean, it's a straight bullet drop this time.

　When I was in Aurum, it was to power up existing bullets, but the one that's falling now is the first one I've ever seen.
　It was distinctly different from the ones I'd seen before, with letters and patterns carved into the jacket like crawling worms.

　As soon as I picked it up, I didn't hesitate to put it in my gun.

　As soon as I held it, I knew it was an infinite series of bullets.
　The same as the thunderbolts and recovery bullets I have now, these two.
　An infinite bullet that doesn't disappear even if you shoot it.

　So I loaded it up and immediately gave it a test shot into nothing.

　After I fired, the cylinder flashed for a second.
　Another shot, and the cylinder, with a new bullet in it, glowed.

　The bullet itself was a little slower than a regular bullet, and so far it didn't seem to have any special effects, but...

　I shoot again, it still glows in the cylinder.
　It somehow reminded me of the monster I saw earlier.
　After cutting me off, the magic bullets increased in brilliance, and the current light is similar to that.
　And along with the brilliance, I felt the monster became stronger.

''A bullet that gets stronger with every ...... shot?''

　In my mind, a spectral sword that becomes strong by sipping on a person's lifeblood, that kind of thing, came into view.
