Surprised!

Naito was rendered speechless while looking at the newcomer.

'That's.... what is that thing?' Naito's pupils constricted as his chest started to palpitate.

His steeled nerves were once again startled. Naito didn't expect that he would be seeing an alien so soon!

Although he had already guessed that there are more peculiar races out there, Naito was still taken back seeing a real thing.

After all, thinking and seeing were both completely different.

As people say, 'seeing is believing.'

Biting his lower lip, Naito forced to calm himself. Seeing that 'his' classmates didn't even blink in surprise seeing the 'alien', it's easy to guess that they were already familiar with it. Therefore, as their 'classmate' who had already 'interacted' with the 'alien', acting like this might cause some unwanted attention.

'Why do you look so surprised, Naito? Didn't we already get familiar with this thing?' Such questions could possibly ask to him.

The 'alien' has the appearance of a yellow octopus. It is about three meters tall and possessed a large, bulbous head with a large smile that seemingly rare to break or move and small, beady eyes. It used two tentacles as arms, each having two feelers as fingers, and utilized the rest of his tentacles to walk. Furthermore, it had a pair of hidden nostrils, which made him appear to have four eyes if detected.

The 'alien' was clad with a black academic dress, a small black squarish academic cap with a yellow tassel, and a large black tie with a yellow crescent-shaped moon on it.

[Koro-sensei]

The 'alien' steadily and leisurely its lower testicles to walk in front of the students.

"Once again, good morning, my lovely students." Even though the 'alien' had spoken, its wide smile didn't move or open. Naito guessed that the 'alien' mouth was located at an unknown part of its body or it didn't have a mouth at all and was using its pores to release and create its voice.

Naito saw 'his' classmates didn't speak and just stared at the 'alien', so he just acted like them.

Just staring at the 3 meters yellow octopus-like alien with its huge smile plastered on its face.

Thud!

Suddenly, one of 'Naito's' classmates with blue hair stood up and loudly spoke.

"Stand up!"

Thud! Thud! Thud!

As though the blue-haired student was a military commander, the students complied with his 'order'.

"Bow!" With that said, the blue-haired student, Naito, and the rest of the students bowed their heads toward the testicle alien.

"Good morning, Sensei!" The blue-haired student greeted.

""Good morning, Sensei!"" Followed after the rest of the students including Naito.

While his head was still hung down, Naito's eyes would gleam occasionally.

'This 'alien' seems to be 'our' teacher… and from what the information I've gathered so far, this 'teacher' was also the one who had destroyed the moon...' Naito thought. Although Naito was still not sure if the one who destroyed the moon was the 'alien' in front of them, the probability of it was 38%.

"Raise your head!" The rather soft voice of the blue-haired teenager rang once again.

Hearing his voice, Naito and the others slowly retracted their bow.

However, as soon as Naito raised his head, the first thing he saw made him dumbfounded.

Naito rubbed his eyes as if something out of ordinary had happened. Naito looked at his right side, then left side, and then behind. From the seemingly previous cheerful and normal students, the teens around Naito suddenly changed into violent gangsters with various firearms in their hands.

'Is that Ak-47? Oh, that' a Gloc-'

"Fire!"

Ratatatatata!

Bang! Bang! Bang!

Sounds of guns being fire immediately reverberated inside the 'peaceful' classroom.

'Holy shit!'
