Vol 1 Chapter 1 (2/2)

It is a German 《Headphone Fuzz》 called 《Willer Corp Manufactured Prototype 42》

Due to the fact that it places an overly large burden on the body and mind, it never entered production, but I loved it I loved using it to si it

I put the headphone inThat is all I need to do With this, I would probably be able to deal with any threat that co me At least, I had always been able to before

I sit on the bed, and look at the door to my room If my real identity was found out, and if my real purpose was discovered on top of that, then it wouldn't be strange for 《Metropolitan Kichijouji High》 to set assassins on me, but ——— it doesn't seem to be the case

”Ha, haha”

I laugh thinly and lay down on the bed, looking up at the ceiling

”Like I thought, they are all trash”

At that s I take it out from my pocket and press the 'accept' button A voice sounds through my headphone

”Who is it?” I said, and the voice of the caller belongs to the female interviewer from earlier

”Even the way you answer a phone call is rude, isn't it, Arisu shi+nnosuke-kun?”

”Well, I never thought that I would receive a call from Sensei So how may I help you?”

”Classes start tomorrow so please come to school”

”Where to?”

”The 《Girl Killing Curriculu, class 5”

”Class 5 I understand Anything else?”

”Saku him like a fool”

”Who cares about that”

”Ah-haha Your mouth really stinks”

”No, no It's not my mouth but my personality that stinks, Sensei”

I hang up the phone

Classes start tomorrow

Classes for the sake of killing sick girls like my little sister

I look up at the ceiling with half-opened eyes, and murmur to myself, ” Well, I've finally returned to japan, Saki”

The next day

Was a transfer student's first day, filled with excitement and anticipation

I walk, s

Silence greets me at school

In the corridor

Looking up at the plate with 《Girl Killing Curriculum Class 5》 on it, my feet halt

The time is 8:15 AM

Thehomeroom started at 8:10 AM so I ithout a doubt, late I heard that transfer students should go to their classroo homeroom, the teacher would want to announce that there would be a new transfer student and introduce ood time now, I suppose

I open the door to the classroom

Take a step forward

The students in the classroom number twenty

It doesn't seeirls Perhaps, the nuht be a little bit more

While a 《Headphone Fuzz》's poas also deter to a certain research paper I saw frouys in that respect Though since I'irl, I'm not the least bit interested in that research so I don't really know the details

The students look at me

Following that, the person who appears to be the homeroom teacher ——— actually the feaze on me

She seeh heels A 《Headphone Fuzz》 which rese in her left ear It seeht brain An eer than Sakuma-sensei, I suppose?

”Hi, Arisu shi+nnosuke-kun Welcome to my class”

”This is your class, huh?”

”Ah-ha, I can't have you co”

”So this is your class, huh, Sensei? I'm really honored”

The ferin and she says, ”I'm Honjou Tsukasa Twenty-one It's okay not to address me as Sensei, so you can call me Tsukasa-chan ♪ ”

”Yes, Sensei”

”You really are an unpleasant guy Well then, let me introduce the new transfer student This kid is Arisu shi+nnosuke-kun He's transferring into our school froh Despite that, as a ician, his skills, learned from heaven knohere, are not too shabby and he probably won't be a burden when it co labyrinths He's only interested inthe intervieas really surprised to meet a piece of trash who had the audacity to declare that openly Well, do you have anything you want to add?”

I say, ”Nothing in particular”

”Then, you don't need to introduce yourself anymore?”

”If that's okay”

”Well, in that case, it's not Please introduce yourself”

My expression clouds, and I look at the students with half-opened eyes By noas already done checking the faces of most of the students

Eight guys

Twelve girls

All of theht or left ear Obviously If you don't have a 《Headphone Fuzz》 here, you can't do a single thing

Such headphone-typedevices were special devices whose use was only granted to individuals belonging to either the anizations in japan, or those ere tasked to raid 《Labyrinths》

Individuals ere not granted per them

They are treated like guns froh in the present day, the uns), except that their power is on a different level fro subtleties are different Since they are packed with a genocidal amount of power that can create major incidents if they are mishandled

Thus, they are heavily restricted devices The civilians are only allowed to use ies eoods Even for the military, their headphones are adjusted to a level usable by the majority

Therefore, the only ones allowed to eic that can forcibly stimulate their brains almost to their lied with an ID number and officially controlled by the country

And even a such elites, only the considerably talented ones were allowed to enroll in a place like 《Metropolitan Kichijouji High》

Elites

” elites, huh”

With half-opened eyes, I sathered in this classrooave a simple introduction of myself

” it's troubling when I' about myself but ——— just as said, I'e of the class, so please don't concern yourself with me too much”

A few of them appear uninterested in me

A few of them appear to dislike me

A few of theoodies, direct a pleasant, friendly gaze at me

And I have zero interest in any of them

Honjou Tsukasa-sensei says, ”Is that all?”

”Yes”

”Then sit down In the empty seat”

The empty seat is located in the last row beside the

And the top of that desk is decorated with a flower that appears to bethe dead

It probably isn't intended as harassment of the transfer student, I suppose

The person who originally sat in that seat had probably died

It was a flower placed for that deceased

This was that kind of school

I sit at my desk

I look down at the floith half-opened eyes, and gently put the vase containing that flower down on the floor

I can feel the gazes of a few people turning hard Were they the friends of the person who used to sit here?

But, that doesn't matter Since we aren't here to have fun

I narrow my eyes

And look out the

Once again in the schoolyard, the Nor for their PE lesson Not one a them wears a headphone It isn't because a headphone would interfere with their PE lesson

It was because they aren't allowed to use one

Or, they aren't interested in absurd things like 'putting their lives on the line and killing girls that bring forth extra-dimensional labyrinths'

That is indeed a wise choice, I think

Since Even if I can't beco, soovernment

Or, Even if I can't save the world, someone will save the world: the country, the military, or corporations

In that case, putting ician is an idiotic thing to do ——— I can understand that kind of reasoning

Thus, this was a classrooathered

A classroo their lives using ic, while others lived peaceful, tranquil, ordinary, happy lives

Sensei says, ”Well then, this concludes our ho for lessons to start, take the tih the school handbook”

I look up, then openAnd take out a reasonably thick booklet

Metropolitan Kichijouji High

《Labyrinth Diseased Girl Killing Curriculum》 ——— School Handbook

The contents of the handbook are:

Metropolitan Kichijouji High is an institution established by the government, with the approval of the country, for the purpose of dealing with labyrinth–diseased patients at the onset of their illness

This school deals prie-limited labyrinths, which can only be infiltrated by those who are nineteen years or under

It is pri in Kantou region (In the event that the labyrinths which appear in North-East range, Central range, or Kinki range are too h schools to handle, there's a possibility that ill be deployed there)

In the event that infected girls having an onset of their diseases appear, the cooperating research center attached to the school will iations of the labyrinth brought forth by the diseased girl (Theresearch center currently is Taikou Pharmaceuticals)

The investigation focuses on:

The girl's personality

The structure (irl

The obstacles inside (enemies, traps)

The girl's weak point

The tiirl becomes an 《Eternal Labyrinth》 and envelops and anchors the surrounding area with the labyrinth

In parallel, the school charged with dealing the target girl will conduct a lesson/lecture covering the investigation's results for the students of the 《Girl Killing Curriculum》

In most of the cases, the tiirl is five hours

In the last hour, infiltration of the labyrinth to deal with the girl will take place

In those six hours (in total), everyone should work together and, with the resultant increased efficiency, kill the girl and save the world

Please do your best

Well, that was basically what the handbook was about

I sether, huh”

I drop the handbook onto the desk with a thud

Before I knew it, the ho over and more than half of the break-ti the handbook

Then I realize that a nu at me

The at from them is tense, yet lukewarm

Fro them, one person comes forward

She is a slender, petite girl about 150 cm tall Her beautiful blond hair is tied up into a ponytail However, it doesn't look like it was dyed Her natural hair color Her eyes are pale blue With fair skin I wonder, is she aspirit Her 《Headphone Fuzz》 is in her left ear

In other words, she is an emotion-type

A genius type

A type that is hard to deal with

The girl points straight at me and says, ”Hey transfer student, I shall now tell you the rules of this classroom”

See, she's hard to deal with

I look at her with half-opened eyes and smile

”Aah, that'll be a life-saver I'm kind of disconcerted by a new classroom”

However, ignoring ainst the chest area of her sailor unifor her sharp, pointed chin arrogantly like she doesn't care

”First, youof this school And that's rades in the school year and the boss of this class”

”Hehyh, Boss-san huh”

”I have already cleared labyrinths tithout dying, killed the labyrinth diseased girls and saved the world”

”Fuuhn”

”Furthermore, I have raided eternal labyrinths four tiic Converted fro”

”Ah, that's a”

Four times

She had raided eternal labyrinths four times

That really was an a

By the way, I have already raided eternal labyrinths seven hundred and twenty-four times ——— but, I don't feel the need to say that Since it was a number I could achieve at places where inhumane activities took place thanks to the mad scientists and powerful people of s labyrinths on a daily basis without even any safety gear and I had to keep using ic at levels which could have ripped my brain to pieces while in the labyrinths

Thus, in a peaceful, safe, quiet country like japan, for a person the sae as me to have raided eternal labyrinths four times, she would be quite coirl labyrinths that still had a tierous and the chances of dying in theh

In other words, this girl is coic Converted froe if she was a super star with a number of corporate sponsors ——— at the moment I think about that, Gunjou speaks

”It's not so I need to be proud of, but I currently have 7 corporate sponsors supporting me”

She is pretty openly proud of that More like she gives no signs of trying to hide her bri confidence and puffs her chest out The size of her chest couldn't quite nitude of her confidence, it seems

With that, I knehat kind of person she is

A haughty, impulsive idiot

But well, sheher She should also be well-connected a results, to have such connections at her age, she her echelons of society

Her high class 《Headphone Fuzz》 is proof of that

《Mitsutomo Heavy Industries Made ・ Water-Death Type 1》

One can tell from the name that it is japanese-made

” so?”

On hearing et it?”

”In other words, in order for commoners like you all to survive, you have no choice but to follow enius like me This is the only rule Get it?”

Gunjou stretched her fair hand out

”Don't tell rab your hand?”

A smile then surfaces on Gunjou's face

”I want you to humble yourself and subordinate yourself to me Most of the class are under my command ——— they survived because of my protection”

”Hehyh I see”

”Or are you going to make an enemy out of me? Like him?”

Gunjou points her finger at the corner of the classroom

Directly opposite from my seat, the last row of the classroom The seat before the door

A guy with gray hair sits there He has sharp eyes The color of his irises is a little strange They are red A cold red Those red orbs look at me

”It's not like I'h?”

”You are, aren't you? You don't want to co with me, Hishi+ro shi+ro”

Gunjou speaks the guy's name

Hishi+ro shi+ro ——— seeuy's name Despite his red eyes, his name is 'White(shi+ro)' What kind of joke is this?

shi+ro too had a 《Headphone Fuzz》 in his left ear Hey hey, is this class full of emotion-types?

He is using a 《ROLAND Corporation Special Use Type 0》 japanese- special but it is hard to handle and no si If he had it modified, then he would be a force to be reckoned with

shi+ro says, ”Hah, anyone who doesn't listen to you is an enemy? Queen-sama”

Gunjou spreads both hands and smiles

”That's right Useless ordinary people should just follow me obediently”

Dohn, while re student The student whose desk got kick quivers with a start

”WTF We haven't determined who's better yet”

”I thought it would be obvious froo for real? I don't really h”

In an instant, snap snap snap sounds ring out froers

Their 《Headphone Fuzz》s are activated

Their movements are incredibly fast

It see talk

The classroom tenses

No one canout from them

It looks like the entire class revolves around the two of them

It really is so I wasn't interested in

” well, just go ahead and do what you want”

Both of them are just trash that stands out

I stand up Start out of the classroo

”Hold it right there”

”Stop”

Both shi+ro and Gunjou speak at the same time Which reminds me, Gunjou's name is also a color White(shi+ro) and Ultraether?

It looks like the entire class revolves around the two of them

Gunjou says, ”You haven't said who you are going to follow”

shi+ro says, ” your aloof attitude also pisses me off hey”

They are really troubling people This really is a classroom where a bunch oftheir lives to save the world

I smirk with half-opened eyes

”Don't bully the nervous transfer student, please”

”Then co”

”Forget about her If you prove useful, I'll protect you”

”Haha, I'm sure popular Don't tell me my time has come? Then, how about this? I'm really a whore on the inside, so whoever pays more, I'll join that person Now, bid to your heart's content”

””Wha!?””

Both of thehtly surprised faces

”Ah-hahaha”

Laughing, I walk out of the classroom

I can hear the raging voice of Gunjou from the classroom

”A great person like me even came to talk to you, what's with that attitude!? Everyone, just ignore that fellow! Ignore him completely!”

On hearing that, shi+ro laughs

”Ha, hahaha, the rich girl is getting angry for being made fun of”

”You are also being ridiculed, aren't you! I'll kick your ass!!”

”Try me, bitch!”

I gradually put distance between less conversation

Along the corridor

The ten- back to their respective classes Down the corridor stands the girl Iinterview

Kiryuu Kiri

A 《Headphone Fuzz》 is in her right ear

A left brain type

The type who ic rationally

Different fro the sailor uniforh》 It sees bothersome

”Yaahh, we ain, Mr Aloof bastard”

”Who are you? I don't remember you at all”

”Liar liar You reacted to my face, and your eyes i pervert”

On hearing her words, I do what she said, and look at her breasts with half-opened eyes I stare at her breasts, bulging fully against her clothes

”Hey, I'll be e at them,” she covers her breasts with her arly

”Eh, but I'ht?”

”Jeez, your personality is bad as usual Did you e to make any friends?”

”Of course Roughly about hundred people”

”This school has five classes of twenty students each, so there should only be a hundred people in total though”

”Aah, in other words, I'm friends with everyone except you? Sorry, I just couldn't click ith your physiology”

”Ah-haha Should I kill you, jeez”

Her words, unlike Gunjou, are probably a joke Those ear 《Headphone Fuzz》s in their right ear wouldn't be swayed by a moment of emotion

”But seriously, it won't do if you don't make any friends Once you enter a labyrinth, you won't make it alone,” Kiri says

”Hehyh, I see I didn't know”

”I', a lone ill die, you know?”

”Then, did you e to make any friends?”

Kiri grins

”Of course, with my beauty”

”Shut up”

”Ah-haha Well well, let's both work hard I'ht be different but the goal is the same, so do look out for me e meet there”

”I don't want to”

”Here we go again”

Ignoring her, I start walking

And pass by Kiri

She turns around and asks, ”What about classes?”

”Skipping”

”Eehh, maybe I should skip too?”

”Do as you like But, don't come near me”

”Ah-ha, even though you are just a lonesome kid~”

””

Feeling glooer reply

She was probablytalents, and then in tiet their help, I suppose

Though I have no idea why she would think that I was strong ——— maybe she knows my true identity to a certain extent While a little investigation wouldn't reveal ence institution overseas, and I had clashed with the said organization, then the possibility of her knoho I am was not zero

I turn around for a moment

And narrow my eyes at Kiryuu Kiri's back

Then I begin to consider the possibility that she's an agent of another organization It is possible

Because, even when compared to the other labyrinths in the world, there is an abnormally special 《Eternal Labyrinth》 under the influence of this 《Metropolitan Kichijouji High》, which was surely y from it

I shi+ftthe corridor

Beyond the wall is the back of the school

Behind this school lay a 50 km radius 《Eternal Labyrinth》

Each 《Eternal Labyrinth》 has its own code-na to differentiate one from another

The harder it is to return alive froes from 0 ~ 666

——— Angel 121

——— Flames 65

——— Flash-node 10

——— Water-Death 7

And so on and so forth

At present, humans are able to clear a rank 12 labyrinth with no casualties Beyond that rank, deaths would definitely occur Or the raiderstheir hands on any kind of technology

However, the higher the rank of a labyrinth, the higher the level of y that slept in it, and anyone would want to raid a high level labyrinth and bring back its technology

And behind this 《Metropolitan Kichijouji High》, ten years ago, the hardest labyrinth in the world appeared and lay there

The labyrinth was coveted by military-affiliated personnel around the world ——— but, it was at an overwhelht back anything

By the way, the nairl who came doith the 《Labyrinth Disease》 and became the 《Eternal Labyrinth》 of this Kichijouji, was ———

Arisu Saki

The code-name of the labyrinth is Apocalypse

Its rank is 666

《Apocalypse 666》 ——— is its official name but, in truth, this isn't what it's called

The nairl who came doith the disease was Arisu And, the raiders who returned were as good as none From these two points, to parody the world where one would easily be lost and find it hard to return from in the famous story of 『Alice in Wonderland』, at some point in time, the labyrinth was dubbed:

《Apocalypse Alice》 ———

In other words, ed by this 《Metropolitan Kichijouji High》 for its own interests

””

I further narrow

And at the sas

The break is over

Biih Biih Biih, a siren-like sound rings throughout the school

”What a strange bell,” I mutter To which Kiri, who is a short distance away, speaks Her expression is, for some reason, tense

”shi+nnosuke-kun, did you properly read the handbook? This isn't the bell”

”Hn?”

”This is the sound to signal the appearance of a diseased girl”

”Wha”

My eyes widen slightly as I look at Kiri

The siren continues

”This is an announce Curriculum Please return to the classrooawa Prefecture We'll begin the lesson in killing the girl”

Kiri starts running

”Let's postpone the skipping of classes I' back to the classroom And, also, please really look out for irl”

As Kiri is about to pass me by, she stretches out her hand to hi-five me

——— Let's work hard together to kill the girl

I don't return her hi-five

”Haha, as expected, your personality is really bad”

I don't want to hear that froht but didn't say

I too turn around and head back to my classroom Just at about the same time, Honjou-sensei is about to enter the classroom, with a thick stack of documents in her hands

They are probably docuawa Prefecture

The profile of the girl

Her interests and hobbies

About the labyrinth brought forth by the girl

The results of the investigation by the researchers and scouting corps are all there

I ask, ”Sensei what's the nairl?”

It'll be a bue as my little sister, I think

Sensei answers, ”That kind of thing doesn't irl We only have six hours so hurry back into the classroom!”

Dohn, she knocks on the door to the classroom

”Now, quickly kill the girl and save the world!”

I enter the classroom

Kill the girl and save the world

I look at her with half-opened eyes,

”Hahh this world is really disgusting”

In a low voice, I mutter as I smirk
