He was sure that he had that look that Wrath, his friend, and mentor, loved to see on his face.

The one that always made him crack up because, and he quotes, 'he looked like he wanted to do nothing more but die'. Which most of the time, was not that accurate, since he only made that face when they (They being Black and Wrath) asked him to do a move that was too advanced for him.

But now, he really did want to do nothing more but curl up in a small ball and die.

Kuroko absentmindedly moved his hair out of his face as he taught, letting everyone get a look at the scar that so many students pondered on its origin.

Honestly, he felt like such an idiot that he hadn't connected the dots earlier.

With scrutinizing eyes, he mentally compared Kuroko, the Japanese teacher, between Black, his mentor, and his friend.

Kurokos hair was a little bit longer than was normal in the professional world of adults, but oddly enough, he made it work. His hair was styled in this odd way where his hair was swept to the side, with a lock of hair hanging over his right eye. Just long enough to conceal the prominent scar on his brow, but short enough where it didn't completely cover his eye. His clothes were nice and neat, and he was wearing a fitting black dress shirt with matching slacks and shoes. He was polite and well-mannered, even when his students and coworkers were being rude to him.

While Black was a person who wore all black clothing from head to toe. With a black beanie, cloth face mask, a black hoodie, along with black joggers and combat boots. The only part you were able to see was his eyes, and his eyes were black when he wore his contacts. Black was a person that was snarky, and easy to anger at times, completely unlike his school persona.

Still, he should have realized it since he saw Black almost every night and Kuroko six times a week.

He looked around the room as his classmates left. If only they knew that their beloved teacher, the same one that everyone respected both as a person and as a teacher, was known in the underground fighting world for his skill and almost blemishless record.

After waving his friends off, he stayed behind as the rest of his classmates left school for the day.

Akira stood in front of his teacher's desk nervously, looking everywhere but at the man himself.

He was somewhat startled when his teacher suddenly chuckled. And it wasn't until that moment when he realized that it sounded exactly like Blacks chuckle would if it wasn't muffled by a mask," Cat got your tongue?"

He pouted at that," I just found out that my teacher is also my mentor at illegal fighting, what in the great fuck am I supposed to say?"

Black snorted at Ire's words before replaying with a grin," Well for one, we're still at school so maybe tone it down with the cussing."

Ire immediately lowered his voice," How did you even find out?"

Black casually shrugged his shoulder, "Honestly, its because I saw a bruise on your arm that I knew you had gotten from a fight. It wasn't hard to figure it out from there."

Ire stared at Black for a few seconds before tiredly running both of his hands down his face while groaning," You have got to be kidding me." That had to be the stupidest way he had even had a secret exposed.

He chuckled at his student's response, the sight giving him a sense of deja vu.

"And what about Wrath? Is he also a teacher here?"

He got a snort in response," Oh god no," Black waved his hand around flippantly," Believe it or not, that guy is an accountant for the police. He manages the finances for a few departments around here."

Ire stared at him with wide eyes before slowly saying," So he works for the police, while fighting at an illegal fight club? The ones that the police try to stop?"

"Yep, which is why you won't be finding out his real name any time soon. Snitches get stitches after all."

And that was a saying that was very common in the underground fighting world. Anyone who willingly gave up information or reported the fighters, more often than not, disappeared for a while. Granted, they did come back, they just didn't come back in the healthiest condition, if you caught his drift.

Still, he was somewhat offended at the insinuation that he was not to be trusted, "Hey, you guys can trust me! I won't tell anyone!"

Ire did not like the way Black gave him a close-eyed smile as he repeated," Snitches get stitches Akira."

And that was the biggest indirect sign he had ever gotten for him to just drop the subject and just stop asking questions. He wasn't an idiot and get could definitely get a hint.

"Do you have any more questions?" The grin was gone, and he looked like his quiet and polite teacher again. But Ire knew that that was not the case, "Does this mean I get extensions on my homework now?"

That made Black start chuckling before he softly said," Yes, but you'll only get an extra day from me. Of course, that doesn't mean you can slack off on your studies."

"Oh yeah I know that, I still want to be a doctor after all."

Wow, that sounded ridiculous.

There was a teacher and a government accountant that fought in an illegal fight club, and they were training an aspiring doctor to dominate all of the others in said fights.

That sounded like something straight out of a fiction novel

"That's a great career, but we kinda have to admit the irony of everything." Black said that with a grin on his face since he was just as aware of how weird their situation was.

Ire returned his grin before commenting," By the way, you're oddly calm about all of this. I would think a teacher would be a lot more concerned that their student is fighting in illegal matches."

Black dismissively shrugged his shoulders," I was once in your position, I'm not sure why you fight, but I was very frustrated with life when I was a teenager. I got to the point where I was very temperamental and just angry all the time. And fighting was my release," Black leaned his face against his fist as he spoke, a sad smile on his face as his eyes looked on wistfully," Believe it or not, the skills I had learn from fighting and the friends I made saved my life in my second year and changed my life for the better."

Ire stared at Black with wide eyes. He knew that his mentor had gone through some shit, he could tell based on the way Wrath had to restrain Black more than once after Ire had accidentally spooked him. In fact, that was one of the first things Wrath had told him, that he had to be careful on how he could approach Black or he could end up with a dislocated shoulder. And if the internet told him anything, it was a trauma response.

But he definitely hadn't expected Black to tell him something like that.

"I settled down my third year, but I fell in love with fighting. You don't have to tell me why you're fighting, but do know that I understand that you have your own reasons and I will respect them. Besides, you got me and Wrath watching over you, and we won't let anything too bad happen to you, you're still a little kid compared to the both of us. And you have much to learn young one." Black reached up and playfully ruffled Ire's hair, much to his annoyance.

Ire pouted as he smacked away his mentor's hands," You're not that much older than me though, aren't you like 22?"

"24, but I appreciate the confidence in your answer, makes me feel younger."

He snorted at that," You say that like you're some 40 year old woman trying to fish for compliments."

This time, it was Black's turn to stare at him as he said," Well that was oddly specific."

"And you're oddly...blue...?" His attempt to give a Wrath-like comeback truly fell flat on its face. And the only thing he could do was blush as Black cackled and tussled his hair again.

"Like I said, you have much to learn young one."

He pouted.

Black laughed even harder.
