(2) ④
Teacher's Comment:
That's right You can write the angle with the symbol π instead of ° Your answer is perfect
Tsuchiya Kouta's Answer:
(1) X = probably 3
Teacher's Comment:
I think you're trying to slack off by saying ”Probably” Even though you're close, I can't give you credit
Yoshi+ Akihisa's Answer:
(2) Probably ③
Teacher's Comment:
I have seen plenty of students' attempts before, but you're the first who tried to slack off on a multiple-choice question like this
”Yoshi+! Kinoshi+ta's troop started the fight with Class D in the corridor!”
With her ponytail swinging behind her, shi+mada, as placed in the same troop I was, ran towards me Under careful observation, you could see that she was tall, with long legs, so why doesn't she look like a girl? Which part of her rong?
”Ah, maybe it's the flat chest?”
”Let ers one by one! Evenly!”
Oh, no, I think I just stepped on a landmine
”L-Let's just stop there We need to focus on the War!”
The troop that was fighting on the frontlines was the vanguard led by Kinoshi+ta The backup troop we're in was located between the frontlines and Class F I don't re an offer to be troop leader, but now I have to take the responsibility to lead everyone, so I need to focus
First, we need to get a feel for the atmosphere of battle If I listen closely, I think I can hear sounds of battle couard troop
”Now Co!”[1]
”I Irono to the remedial room!”
”Shut up! The prisoners of ill be staying in the remedial room and will be specially lectured until the battle ends! I' it will take to end, but it looks like I'll have enough time to lecture you!”
”P-Please, let h the torture!”
”Torture? That's not true It's just a marvelous educational lecture By the time it's over, I'll have educated you into a standard student whose hobby is studying, just like Ninomiya Kinjiro[2]!”
”D-devil! So
OK, now I have a good understanding of what a Summoner Test War is
”shi+ive the order to the troop”
”OK? What order? What do you want me to say?”
During a dangerous tiive:
”Retreat!”
”You coward!”
She used the hidden art that attacks both eyes!
”Ow, my eyes!”
”Did it wake you up, you big idiot!? You're the troop leader! How can you run aithout putting up a good fight?”
Was the pain in my eyes necessary to clearlike this, she should have just punched or slappedmy eyes!
”Listen up, Yoshi+ Our ht? During the ti their test scores, we need to hold the front line If our troop runs away frouard troop won't be able to replenish their scores smoothly”
It was rare to see shi+ive a serious opinion
What she just said is true; the reatly affect the result of this War Instead, I was thinking about running away just because I was afraid of suffering from a remedial
shi+mada, you are so brave! I don't knohy, but I' stabbed?)
”I' I'll throay the fear of the reht”
”Good I don't think we have anything to worry about, though Although we ainst one enemy at a time should be fine”
That's right Even though we have lower scores, it's not the deciding factor in the War Depending on our tactics, wethis War
”You're right OK, I'y!”
”That's the spirit, Yoshi+!”
We all raised our fists No problem, we can do this!
As our morale rose, a scout went up to shi+mada
”shi+!”
”Retreat!”
Wait a hteous speeches you just gave!
”Yoshi+, we can retreat first, right?”
I had a feeling that thisproblem, but maybe it was just me
”OK, we should run away first! It's too difficult to fight now”
”That's right, we already did our best”
I looked back towards the direction where Class F was
Yokoda (Class F) as supposed to be staying in the classrooht behind me
”Yokoda? Why are you here?”
”I'e from the class rep”
Yokoda looked at the e out loud:
”'If you dare to run away, I will kill you!'”
”Everyone charge!”
When I came to my senses, I was on my way to the battlefield It was all for the victory of Class F!
Suddenly, there was a pretty girl in front ofin my direction
”Yoshi+, you're here to support me!”
Oh, it was Hideyoshi+ What should I say; this guy looked cute no matter the time or place
”Hideyoshi+, are you OK?”
”Yeah, I soreatly reduced”
”I see, then how about your Being?”
”Too tired toanymore”
”OK, then you better do some tests to replenish your score!”
”You're right There h time to have tests for each subject, but it still helps to have even one or two subjects' scores replenished”
He i behind hiuard troop It seems that their numbers were fewer than when they left A lot of people must have been sent to the remedial room
”Yoshi+, do you still remember the rules of a Summoner Test War? If a teacher's not around, you can't su!”
”I know that!”
It was just as shi+ht, we need to coe:
Fuhts Related to
Classroom Facilities and the Summoner Test War
1 In principle, the fight is between classes Under the supervision of a teacher of any subject, students s Also, a fight that uses cumulative scores must be supervised by the Head Teacher
2 A studentis equal to their last test score The cumulative score is the sum of every subject's latest test score
3 A student's score will be reduced proportionally to the strength that their Being loses in the fight Once a student's score is reduced to zero, their Being will die and they will receive remedial classes in the remedial room
4 A studentis not dead
5 If a student fails to perfor, that student will be considered as forfeiting the fight, and therefore will receive remedial classes in the remedial room as punishment
6 The valid range in which a Being can be summoned is a circle with a radius of tenteacher (may vary between teachers)
7 The fight s Any su will be punished
8 The war ends only when the opposing class representative is defeated As long as they are under teacher supervision, a student may use any method or tactic in order to win the War This is the 'war' that uses test scores as weapons Those ish to participate must be mentally prepared
These are probably all of the rules! Although there were soeneral rules for this War If you didn't read through theht have missed the s to decide the result, but the students can use other methods or tactics besides test scores”
It see now, so the subject ere fighting under noas the cumulative score mentioned in the first rule
”Yoshi+, look!”
shi+ beside me, shouted loudly What happened?
”It's Mr Igarashi+ and Mr Fuse! Those Class D bastards, they brought the Chemistry teachers here”
I looked carefully The Chearashi+ and Mr Fuse, were standing at the corridor that linked the new school building to the old one
I see The duration of the War would be - in our case, the school's Head Teacher- so they're trying to increase the number of supervisors to finish us off in one shot?
That's why Hideyoshi+ needed to retreat earlier than we had originally planned
”shi+mada, are you confident with your Chemistry score?”
”Not at all; I only get around 60 every time”
That's what could be expected from Class F No ood result
”OK, then, we'll need to stay away froarashi+ and Mr Fuse and head towards the Head Teacher”
”Head towards Ms Takahashi+? Understood”
shi+h the corridor and headed towards the corner
Everyone, look! These was the heroics of the backup troop leader and his subordinates
”Ah, isn't the one sneaking over there arashi+, hurry here!”
”da careless”
One of the students in Class D discovered shi+arashi+, here Oh, no, if we don't suht, it would only take one hit to send us to the remedial room
”OK, shi+mada, I leave this to you I'll be on my way”
”Wait a It's norht? It should be 'Leave this to ht?”
”Those lines are useless in the real world!”
”Y-Yoshi+! You're so mean!”
”Onee-sama! I won't let you run away!”
”It's Miharu! It seeht for my life”
I was standing arashi+, so I can rest and observe how shi+irl fro
shi+mada also prepared to counterattack; she stared at Miharu and shouted,
”Summon!”
At shi+eometric shapes was for syste appeared
The Being that appeared, besides wearing aa -looking eyes that were exactly like shi+hty centimeters If I had to describe it in one sentence, it would be ”the chibi version of shi+ was also the chibi version of its owner, but it was holding a normal sword
”I've been waiting for thistime ever since I was dumped by Onee-sama”
”Wait a second! You should give up already!”
The battle would start any h I was not the one on the battlefield, I couldn't stop shaking when I thought about it
”shi+ she mentioned”
”I don't want you Onee-sama will only be Miharu's onee-sama no matter what!”
”Don't get close to irl who likes boys”
”You're lying! Onee-sama should love Miharu as well!”
”You don't know anything about me!”
So that shi+mada was in a world far away from me
”Onee-sa!”
Both Beings went close to each other, and the battle finally started
”HAAAAA!”
”YAAAAA!”
Their shouts filled the corridors
Their Beings held their weapons high, and started to fight head-on with brute force
”You!”
”Miharu won't lose!”
Both Beings were channeling their forces through their swords Even those atching the fight were thrilled
”shi+ head-on isn't good for you”
”I don't need you to reh to do any special techniques!”
The swordfight was broken ih power, and its weapon fell to the ground
”That's it!”
”damn!”
The opponent iround, and their strength values (scores) appeared above their heads
Class F shi+mada Minami VS Class D shi+mizu Miharu
Chemistry
53 VS 94
shi+mada, why did you inflate your score? Actually, could you even score up to 60?
”Onee-sama, this victory is mine”
The opponent's sas held to shi+ attacked, the score would only be reduced a little bit, but if the neck or the heart was stabbed, the Being would be dead- which would also mean that she'd be sent to the remedial room shi+mada couldn't move at all
”N-No! I don't want to go to the remedial room!”
”'Remedial room'? Hu hu”
shi+ed shi+mada's hand and left the scene
Eh? shi+ht?
”Hu hu hu Onee-sama, there should be an eht now”
”Y-Yoshi+ Back erous than the remedial room!”
That's right, I have the sa as well But
”I will kill you Those who stand against Miharu's love with Onee-sama, I will kill you all”
I ae to rush forward
”shi+et you!”
”Ahh! Yoshi+! Why are you saying that before you fight?”
”Death to all who try to stop me!”
The hands and legs of shi+ had been attacked, so it couldn't oing to die!
”Yoshi+, look out! Summon!”
A voice caawa froht now!
Class F Sugawa Ryou VS Class D shi+mizu Miharu
Chemistry
76 VS 41
Sugawa's Being slashed the eneround
Aw, yeah, Sugaon! It seeht,her lose this one instantly
”shi+ht?”
”Yeah, I'awa Iron- no, Mr Nishi+erous person to the remedial room”
”Oh, isn't it shi+, come with me”
Unlike shi+, shi+mizu's was dead, so she was sent to the remedial room; this was the condition we called ”Killed in Action”
”Onee-saraduate from this school safely!”
After leaving soerous words, shi+mizu was forcefully sent to the remedial room
Froerous duel
”Yoshi+”
”shi+mada, you must be tired You should head back and replenish your Chemistry score!”
”Yoshi+”
”Then, Sugae should be on our way now The War is still going!”
”Yoshi+!”
”Y-Yes?”
”How could you leave me alone and run away just now?”
”I don't re”
This really was a battlefield The killing intent made my skin hurt but there was only shi+mada behind me
””
””
A shortthat this is not good?
”DIE, Yoshi+ Akihisa! Summo-”
”So her to the main troop immediately!”
Sugawa stopped shi+mada's actions and tried to persuade her at the same time
”That's not true! He is the enereatest enemy!”
I couldn't deny what she had said
”S-Sugawa, sorry to bother you”
”Understood”
”Let ive you!”
”Quick, quickly bring her back! I'lare!”
”Wait, let go! I' to kill you!”
After leaving so words, the scary figure was taken away For now, I am safe
”Good While Hideyoshi+'s troop is replenishi+ng their scores, we need to hold the front line! We can't let the enemy take another step forward!”
Angry shouts and cries never stopped co from the corridors
”I won't let you do that! If we can get through the front line, there will be only troops that are replenishi+ng scores beyond it! We need to get through here now!”
To counter my coave out an order as well
This is e!
”Commander Yoshi+! The troops at the corridors on both sides have been defeated! We only have two men left around Mr Fuse!”
”I'arashi+ is! Need backup as soon as possible!”
”Toudou's Being can't make it, please help us!”
daht
I feel like requesting help from the main troop, but that would reduce the number of people needed to execute our plans We can only rely on ourselves to hang on here!
”Tell those around Mr Fuse to stay in guarding status! Swap the guys around Mr Igarashi+ with those fighting using their cuood use of time, and defeat the eneive up on him!”
”Understood!”
Everyone changed formation as told; it seems that they still considered me a leader
”Those bastards in Class F, they're clearly ai to waste time!”
”What are they waiting for?”
Looking at our fighting methods, those in Class D should have started to realize ere trying to do That's not good; it's getting harder to carry out our mission now
”daht the World History teacher Mr Tanaka here”
”World History teacher Mr Tanaka?”
”Class F bastards, do they want to have an extended battle?
It seeht Mr Tanaka to mark scores
Mr Tanaka taught World History, was old, had slow reactions, and had a pretty loosestandard that elco speed was not very fast If anted a longer War, bringing Mr Tanaka would be the right choice
”Yoshi+, Class D brought the Mathematics teacher Mr Kiuchi”
Sugaho had just taken shi+ave ht new inforht?
Mathe standard, but hisspeed was very fast It see a totally different tactic and wanted to finish us off quickly
However, to accomplish our mission, we couldn't be beaten so easily
Yuuji entrusted only one e line, and drag out the battle as long as possible, at least until those classes that were not involved in this War finished their classes
To achieve this target
”Sugawa!”
”What's up?”
We could only use tactics instead of brute force, at least to steer the situation towards a direction that benefited us
”In order to win o spread false information immediately”
”False information? Fine by ht? The Class D front line commander has a loud voice, so even if the tactic succeeds, he can immediately reorder the formation”
Just as Sugawa said, Class D's coh it was really convenient to overhear their tactics, giving false information to confuse them would not be easy at all
”No probleet of the false information isn't Class D”
”What are you trying to say?”
”I want you to spread the false inforo to other places”
”I see, that will definitely have some effect”
”Right?”
”Yeah, leave the content of the false inforood lie to tell them”
”I'll leave it to you”
After Sugawa had said that, he ran off Sugawa loved to do this sort of thing, right? He see so
”If we can't win in a one-on-one fight, we'll have to rely on teamwork!”
Anyway, as a commander, I stayed at the back of the troop It was my mission as troop commander to stay safe, not because I was timid
”Tsukamoto, there's no end to this!”
”Just hold on a bit longer; I'll go bring Ms Funakoshi+ here!”
The bad information for us Class F came when the situation was stalled
Class D was going to bring Mathele) Their aim was to have her become another supervisor instead of ood for us at all If the battle range increased, the difference in our troop forces would be even larger
What should I do? It was probably tiht now
Just as I was thinking this
Dang, dang, dang, dang ”School announcement, school announcement”
