"I want to line up the colors on this cube- all of them, and quickly, with a method anyone could use."

You watched the man in front of you who was sitting on your chair with a cube in his hand, seemingly trying to solve it without putting any effort at all. It kind of bothered you.

You were so close to snatch the cube from those hands and solve it yourself. That man is taking too long.

"How would you go about it," the man continued, grabbing a as he did, "teachers?"

'Ah. Don't be a loser and solve it yourself instead of breaking it apart you motherfucker.' you held in a sigh and keep your posture, not wanting to seem rude or show any disrespect.

"The answer is simple."

The door then slide open, revealing Koro Sensei who probably just finished his class.

And at the same time, the cube in the man's hand broke into pieces as he broke it himself, the pieces falling to the ground creating a messy rhythm as they hit the ground.

"Take them apart and put them back together again. Very logical." He put on a smile, a cold yet charming one that can almost fool anyone who never looked him in the eye.

Others may haven't noticed it yet, but, there's something about his eyes that told you to never put your guard down.

As a teacher, anyway.

The man seemed to finally notice Koro Sensei by the door and his demeanor changed into one where you would thought his smile is genuine. "We meet at last, Koro Sensei."

You hear the door closed and saw Koro Sensei approaching Karasuma before he stood next to him, confusion clear on his face that you somehow could tell.

"He says he's the principal of this place." Irina explained shortly to him, which you nodded at along with Karasuma before he continued,

"As teachers, he's our boss."

Koro Sensei freaked out and proceeded to prepare tea, fanning, messaging and give Asano a... You couldn't make out whatever in the box. Probably brownies or something but you're not sure. All by using his 20 mach speed. "My, my- you've come all this way! Say, might I receive a little bump in my salary? I have something of a knack for clones, you see."

You rolled your eyes at him, chuckling quietly to yourself at how hopeless he is.

"I'm sure it's in your power to-"

"I must apologize." The man interrupted, turning to Koro Sensei who stopped doing whatever he was doing, a unsettling smile still featured his face. "I'd meant to come pay my respects." He stood up from his seat before continuing, "The Ministry of Defense and Mr. Karasuma have told me all about you. I can't claim to understand everything, but... "

He looked up at Koro Sensei, his smile changing slightly into a mocking one, "How very sad you are. Looking to become the savior of the world, only to fall into the role of the great villain who would destroy it."

The tension they didn't even realize was there eventually raised, though they kept quiet and let the man continue whatever he have to say.

"But let's set that aside for now. Struggle as I might, I cannot hope to save the planet from its crisis. Barring the unexpected, I'll stay out of your assassination altogether." The man finished while making his way toward Karasuma, whispering something to the black haired man who give a quick reply after.
