Time Limit!

Looking at the seemingly magnificent scene in front of him, Naito was left flabbergasted.

Although he had already expected that this world was not normal, he was still surprised by the sudden change of situation!

In his mind, he had never thought that his ordinary-looking students could change so much just in an instant!

Turning his head, Naito saw the 'gentle' and 'caring' orange-colored hair girl, who was now firing an Ak-47 with a cute smile on her dainty face.

'…'

When Naito thought that there would be no more shocking than having his 'classmates' taking various firearms out of nowhere and started firing at their supposed to be 'teacher', he was proven wrong.

'What the-' With wide opened mouth, Naito's eyes constricted in disbelief. In front of him, the octopus-yellow-alien was surprisingly moving at a very fast speed!

The octopus alien's speed was too fast that it created several after-images!

Furthermore, the octopus alien was heartily laughing as it leisurely dodging the bullets.

Thud! Thud! Thud!

Failing to hit the target, the bullets could only knock on the blackboard and fall on the floor.

Wait…

All of a sudden, amidst the loud firing noises and annoying laugh of the octopus-alien teacher, Naito's eyes shone in realization.

Squinting his eyes, Naito looked at the bullets that were lying on the ground after bouncing off the blackboard.

'rubber bullets…yes, they must be rubber bullets.' Naito concluded looking at the small sphere-shaped bullets rolling on the floor. In his past life, he and his friends would often play 'war' games using BB guns and rubber bullets so he was quite familiar with them.

'If they are not using real bullets, then…' Naito swept his gaze at the firearms in his 'classmates'' hands.

'BB Gun.' Naito let out a sigh of relief. After all, using Bb Guns and rubber bullets was pretty much better rather than using the real thing!

It's 10 times better and safer!

Knowing this, Naito, once again, fell into deep contemplation.

His head was full of questions with almost no answers!

'Why are they using BB guns against this 'alien?'

'In the first place, why there's an 'alien' teacher here?'

'Is this the same earth?'

'If so, are there more species out there like this 'alien'.'

So many questions with no answers. Naito only had conjectures in his head but he's not exactly sure if they were correct or not.

'My information regarding this world is too small and insufficient at the moment.' Naito decided that as soon as he had the chance, he would immediately gather more information related to this world and particularly to this 'alien'.

"Cease Fire!" A loud and stern voice suddenly A man that looked around in the 30s entered the classroom through the open sliding door.

Ratata…

The students quickly stopped firing.

The last rubber bullet fell onto the ground after bouncing off the blackboard.

"Nyehehe~, Karasuma-san, you're no fun at all!" the octopus-like alien halted his swift and fast movements and looked at the newcomer with its never-leaving wide smile, "I and my students were just having fun!"

The newcomer whose name was Karasuma just took a glance at the yellow 'alien', before shifting his gaze to the students.

"At ease."

Tick! Tick!

The students quickly put back the safety pin as they obediently lowered their BB guns as they corrected their posture; standing straight, as though they were soldiers meeting their superior.

Seeing this, Naito immediately followed the actions of his classmates.

'This guy…' Naito's inquiring eyes shone for a bit before quickly dimming. He quickly formed a few speculations in his head about the newcomer.

'Looking at this guy's posture, expression, and the way he carries himself… he must be a soldier.' In his previous life, Naito would occasionally meet soldiers and with his observant eyes, he had gotten to know their characteristics and mannerisms.

Therefore, he felt that his guess was highly correct.

'

"It's been 3 days since you guys received the mission of killing this alien." After saying that, Karasuma quickly took out a bb handgun and fired twice at the octopus teacher.

Bang Bang!

"You're so wild, Karasuma-san." As always, the octopus teacher easily dodged the 2 fired rubber bullets while showing a set expression on its blob-yellow face.

Surprisingly, its head turned pink!

"Tsk." Karasuma clicked his tongue as he glared at the 'shy' octopus teacher before shifting back his gaze over the students.

"However, in the past days, no one had even landed a bullet on this 'alien's' body. Not a single one!"

Hearing him, the students lowered their heads in shame, excluding Naito who's eyes would shine from time to time.

'Gimme more juicy information.' To Naito, the newcomer's mouth was like a treasure trove that would freely and willingly give treasures in the form of 'information'.

"Especially, you!" All of the sudden, Karasuma's gaze landed on Naito's figure.

"I've been watching you since earlier. Why is that you didn't even bother to pick up your firearm and shoot this 'monster'?"

Numerous thoughts quickly circulated in Naito's mind, trying to find the best solution to solve his current predicament.

'Because I had no idea at all.' Naito was sure that he would be in trouble if he said that.

After a second, Naito's mouth slowly opened. However, as soon as words about to come out of his mouth, someone was faster than him.

"Uhm, please forgive Naito-kun. He's currently feeling ill so he could not able to use his gun." A soft voice rang beside Naito.

'This girl…' That voice was familiar to Naito since the owner of the voice was the first person he had spoken to in this world.

'Don't bring me trouble, girl. I'm not sic-'

Cough! Cough!

Naito suddenly felt itchy in his lung as he unconscious coughed twice.

Fortunately, Naito was able to use his right hand to cover his mouth.

After coughing twice, Naito felt that there's was something sticky on his palm.

'Damn, she's right.' Naito grimly thought while looking at the sticky substance on his right palm.

At first, Naito thought that it was only phlegm and nothing more, but it turned out---it's blood!

"Naito-kun!" Naito immediately felt soft hands grabbed his wrists.

"Don't worry. It's only ketchup I ate earlier." It seemed that the orange-haired girl was more afraid of Naito's condition than he was.

After all, Naito had already guessed his situation.

However, it's too sudden. In that white room, Naito saw a transparent screen that showed him his mission.

And, if he ever failed that mission, his death would be the punishment.

Just from this, Naito easily speculated that the mission had a time limit.

And, the time limit was his condition.

'As time goes on, my condition will probably get worse. Before things go south, I must kill that 'koro-sensei' otherwise, I'll die.'

Coughing blood was a bad sign, and Naito was not ignorant enough not to think his condition was nasty.

It might be a disease or injury, but Naito inclined more in the former.

'This is getting more and more… interesting.' Naito's eyelids started to grow heavier as his vision became blurry.

Naito put his hands on the table to support his body, but in just a matter of a second, his eyesight blackened as he lost his strength and fell forward.

"Naito-kun!" Before Naito completely lost his consciousness, a familiar voice that was filled with worry and anxiety entered his ears as something soft and squishy stopped him from dropping on the floor.

'Damn, that's soft.' With that, he collapsed.
