That voice sounded good.
　That voice bounced well.
　It was a voice that brightly illuminated the dark basement for all intents and purposes.
　That voice contained a lot of information.
　Once you heard it, you could imagine the owner of the voice, even his appearance.

　There are two voices that reverberate so high. However, there was no point in distinguishing between the two.
　Because they both belonged to a young child.

　Because both were the voice of a girl.

''Ahahahaha.......''
"Uh-huh....

　There was no sign of even breathing, and the child's voice continued to maintain the tension of frolicking on the playground. The little footsteps that were caracara resembled those of a shoe hammering against a tree instead of the usual ones.
　They came running, running and coming, perhaps trying to trample all over the playground. A high, clear sound comes with a voice.

　After it passes, the carcasses pile up, and then a new pile of carcasses ... to find a new toy.

　In the hands of the girls, the tools of carnage are held in their hands. It was a messy, stuffy ... and strangely familiar in the hands of children. Like the machete that the homeowner had swung down tens of thousands of times, every morning to chop wood, the machete in the girls' hands felt strangely uncomfortable.

　The silvery machete blades are polished and sharp, and unlike a mere machete, they have a lot of workmanship.

　Running was also a game, and when the girls couldn't find a target to kill, they pushed the machete blades against the wall and sparks flew.

　The rattling and discordant sounds were also played as part of the girls' merry play.



　Inside the deposit, on the underground second floor, the troops were selected from the Fifth Academy of Magic in Balmes. There was a last minute change in members, and the two girls who joined - the sisters of Lea Mea - were running around inside the deposit. Of course, this was not for the purpose of investigation. The student-led mission had already become a mere game for the girls. In other words, it had gone out of control.
　There should have been four members, but only two of the girls were present here.

　The girls still had no idea what was going on inside the deposit. On the contrary, because they had been running around inside the deposit, the two of them were located in the perimeter area.
　Even the two underground levels of the deposit were quite large. It's a perfect playground for the two of them.
　Nevertheless, in this labyrinthine underground space, even if there was a map, it was inevitable that they would get lost.

　They didn't give a d*mn about such things and just went ahead with their whims.
　The number of demons defeated lightly exceeds 20. However, the two of them were so engrossed in running that they were not in a state where they had definitely defeated them, and they hadn't put a stop to the demons that fell because they couldn't move.
　In other words, there were many individuals who hadn't destroyed the demon core.

''Rare, rare, there aren't any strong looking ones at all. If this continues, it's going to be over, isn't it?''
Maybe. It's a little disappointing.
Why don't you just say "it" and "it" when we're alone?

　Mea tells him to return to his original tone, but Rhea gives him a good look.

'A little more taste, Mea?　I think it's better to remember that.
To whom?
"?　To anyone.
Hmmm, that's enough. I'm getting bored.

　Rhea stops pointing out to Mea, who keeps changing the subject, that she's fed up but it's always the same thing.
　Although she has been dogmatically defeating demons as she explores, she was beginning to lose the stimulation of this due to the simple tasks she was doing.

''If I defeat a lot of demons, I'm sure they'll praise me and give me lots of sweets, but oh well.''
Mare is still a child, isn't she?

　Leah bent her mouth as if she was having trouble saying it towards the end of the word, but even she didn't really know what was right, and she was self-satisfied. Although they were twins, they were supposed to be older sisters, in a manner of speaking, so he was trying to act like it.
　Most of all, this was the kind of woman Rhea's ideal image of a woman. I am convinced that Felinella, the older sister who greeted me, would behave like this.

　Thanks to the presence of the child《Mare》next to her, it was also easy for her to play the role of a mature woman.
　But.........Rhea's mouth was sloppy and half-open.

''I want some sweets.
Which one of you is the child?

　While they were having this conversation, they were running dexterously in their single-tooth clogs. Since they are twins, even when they come to a fork in the road, they proceed in the same direction without hesitation, as if they are communicating with each other. It's just a matter of how you feel at the time, no matter where you're going around the same place.

　To put it bluntly, Rhea and Mea are wild children protected in the outside world.
　It was a mouth that learned about magic from actual battles. The outside world is their garden, even if it is a mineral deposit, so to speak.
　The two of us know that there is no purpose in strolling through the garden, and that the two of us are most comfortable when we are at our wit's end. If they encounter an enemy, they just have to think about it on the spot.
　Most of the time, though, you have to take care of them. If it's a beast, we can handle it and eat it, but we don't waste time killing it unless it's unavoidable given our life in the inner city. Because every meal the girls have eaten has made their tongues roar.

　They run through the deposit at high speed, the walls also being a foothold for them to run in all directions. I don't know if he's more of a manager than a guardian for the two of them, or if he's in charge, but Balmes's head of state of the same age, [Cian Videlic], has become the guarantor for their custody. For that reason, miscellaneous expenses related to the two of them also came out of Cian's shallow pockets for now.
　Speaking of a comfortable relationship, there is a history of entering the Fifth Academy of Magic with Cyan - being admitted to the school - and their classmates are probably the closest to each other.

　Without feeling the tension, Mea opened her mouth wide and absent, just because she was bored.

'It looks like we're done here. Let's go back. It's kind of boring.'
Is. How many?　How many?　I forgot to count if I killed him.

　Leah turned her attention to her hand and folded her fingers one or two at a time, but when she finished counting the fifth to make a fist, her brow wrinkled up between her eyebrows.
　Next to her, Mea is also counting, folding her fingers, opening them and repeating.
　But Rhea quit it. The rest of the time, he thought in his head and counted.

　But the wrinkles between his eyebrows deepen, and even his eyes get worse. The number that he defeated in the first place was itself fuzzy in his memory, so he soon hit his head.

''Didn't I kill five?''
'Mmm--I don't need Mea to tell me that.
'You don't have to count anymore, do you?　You weren't asked to count, and you can try what they taught you at the academy right away, but don't ask if you're going to be in a bad mood.

　What they are being taught is mainly general lectures, but of course it is still too difficult for the two of them. That's why my classmates are using the gaps in time to teach the two of us the minimum amount of calculations and such.
　I try to practice it right away, but I don't know exactly what I'm doing since I didn't beat them with the intention of counting in the first place.

　Leah was right, and although it was annoying, I stopped counting.
　At the right time, he catches a demon in the corner of his eye. It was a bizarre demon that reminded me of a lumpy rock, whether it was mimicking or not. Small limbs and a stocky torso.
　Its outer shell was like a rock face, just like the word suggests. The demon with a sturdy outer shell was generally rounded.

　Leah made a small dimple of a smile and her magic power gushed out as if she was influenced by her emotions.
　Then she pulled the cutting edge of the machete in her right hand behind her. And the sole of her foot - a foothold in the air, pushing up her small body as if it were a bullet.

　With an explosive acceleration, Rhea leans forward and lunges at the demon's eyes.

''--!
It's good to see you.

　As if to cross Leah's gaze, Mea takes a swing at the demon ahead of time. Mea often sidesteps, but she doesn't consider any danger to her surroundings.
　Although barely Rhea changed direction and managed to avoid colliding with it.

''Mea, that's not fair!
'Heh-heh. The sooner the better. Rare is so fragile.

　Buying words to sell. Petty arguments are an everyday occurrence. Among them, Mea has always had the upper hand in terms of tomboyishness.
　Because she didn't listen to him in the end, Rhea was always forced to cry herself to sleep.

　This time is one of those times.
　Hanging up the corners of her eyes in a miffed mood, Rhea took a further swipe at the demon that had been cut in half.

''It wasn't dead yet. Mea's meager attacks hadn't killed it.''

　His tone of voice, spoken as if it were a modest and stern fact, was as if he was defending his sister's dignity.

　With a bleep and an accustomed hand, he shook off the demon's body fluids on the blade. However, there is no such thing as blood gluing as it quickly dissolves in the air.
　It's not a matter of concern for the demon that is turning to ashes, but rather a matter of a calm demeanor, as if she was cleaning up her sister's mess.
　Mea had a blatant look of dissatisfaction on her face and zipped up to Rhea.

But, but, but.............................We kill a lot more than Rhea. Rhea's the first one you've killed now.
"--!　It's different. I've killed more rares than mare. Mea are messy, so I haven't killed any of them even if I thought I had!
It's not true.

　That's not true, Mea puffs out her cheeks as she says a second resistance.
　In an argument, Rhea's victory is unassailable. Mea is not good at searching for words, she can only issue one-sided assertions like "no". Mea is aware that her ability to yield to her opponent with words is inferior to Rhea's.
　Perhaps that's why Mea could only stubbornly repeat the same thing in the end. It's frustrating, but it can only be countered by not admitting defeat.

　Where this argument will end up is whether Mea will remain stubborn........

''Ah!　It's not fair, Mea. It's not fair to cry.
Higg..........

　Seeing Mea with tears in her eyes, Rhea's pride in being an older sister is shaken. Arguing, each of those words comes from her position as an older sister. Because she's an older sister, she can't lose to her sister.
　However, if you make Mea cry, there's no point in continuing.

I'm not crying.
'I know. I've killed Mare just as much as you have.
There's one too many...
I've figured it out. The mare kills more people than the rarer ones, sir.

　Maybe the sister is the one thing she can't outdo her sister in the first place. Only Rhea is actually the only one who sticks to the binding of sisters.
　The sisters are also technically taken care of, such as assisting Cyan, and the new Governor Nilhine Quadrille has somehow decided to do so. The only reason for this is because of the paperwork, or for personal registration and other records.


　Rhea exhaled heavily, feeling that she was sighing more and more since she had become a sister somehow.

　A new prey appeared in front of the two of them. The reaction speed was almost simultaneous for both of them.
　The two of them turned the faces they were keeping together at the same time and looked at the back of the huge passage. It was similar to the sound they were making as they scraped the blade of their machetes against the wall.

　It was the sound of the sword being dragged to the ground.
　The sound of crunching, crunching, walking was familiar to the bipeds.

'Huh?　People?
No, sir.

　The monster that came into their sight was so similar to a human that Mea was mistaken. Its dark green body color and well-trained body was close to that of a human, down to its flesh.
　The only thing he wore was a tattered loincloth, and he wore nothing else. In addition, the head, although a bit large for a human, is still within the bounds of common sense. If anything, the physique is so familiar that it's in the memories of Rhea and Mea. In addition, a miscellaneous mask was worn on the face to give the impression of a human expression. It looks like a mask, but that's correct. It was as if it was sewn into the skin.

　A strong warrior, or should I say a gladiator?
　A large man just under two meters tall.

　The two of them mistook him for a human because of his physical appearance, but he seemed somewhat old-fashioned in appearance. Still, neither Rhea nor Mea have been able to confirm that they are demons.

''--!

　Their surprise instantly switched to elation. Another man appeared behind the big man. While the previous big man was dragging a straight sword, the second big man was carrying a weapon in both hands.
　He dropped his lumbering, thick arms, and in his hands he held a dagger with a large curved blade called a halper.
　It was a weapon that was designed for such ease of handling, with the blade of a sickle as a dagger with a handle.

　The big man here held, the weapon seemed to be different from a simple weapon. It's not even different from iron, but there is a sense of foreignness that possesses a dull color.
　That's the only element that would determine it to be a demon.

　The mask also has a different look.
　The eyes, mouth, and the depths of the air holes do not reflect anything. It was as if a pseudo-expression was plastered on a flattened surface with no face.

'Mea, you must divide it between the two of you. Don't cheat this time.'
Yeah, that's fine. You're halfway there.

　Although there were many suspicious points in their appearance, the sense of smell they had developed in the outside world far surpassed that of ordinary people.
　If it was a demon or a beast, there was no way they couldn't distinguish it from a human.


　The two of them started running at once. They started off without hesitation, as if the signal for "Yoyi-don" had sounded. Their speed is still uncommon. The rebound from the bottom of the foot is also a foothold and triggers acceleration by building a magical force field.
　So although it seems like you are kicking the ground, you are actually kicking a magically created foothold.

　The scaffolding is not limited to the ground, and even walls and spaces have footholds for the girls.
　Therefore, instead of going straight, the trajectory of the approaching demons bounced around at high speed, as if it were a rubber ball slamming into the wall.
