"Karma" Sans meets bnha

Coma part 1: teacher

A younger human sans walked in a discreet hoodie as he seemed almost invisible to anyone passing by, I was of course the professional, the best in the field. What field you might ask, it was killing, assassination, whatever you called. In the end, killing is killing, whatever expertise you call it. He stopped sidestepping and using the elevator to the rooftop, a 97 story rooftop to be exact, quite easy to kill someone, just a small nudge to make it look like suicide, of course cleaning the evidence would be a different story. But this time he wasn't here to kill, he was here for his next mission whatever it was. 

"Uh, h-hello." A voice called out as I looked over the city on the rooftop.

Surprised by the unsure way I turned around locating 2 people, looking like newbies. Wait a minute they were newbies. My face contorted into obvious confusion which was obviously noticeable as one of the newbies started to panic as he tried to explain what was happening, "welltheboss-"

"Wait hold on," I say, "calm down then speak."

"My name is Nagisa but people call me viper," the blue-haired boy says.

"My name is karam but people call me karma." a red-hair boy says.

After a couple of seconds, a shot rings out as I backstep to dodge the bullet.

"heya tophat," I say grinning in his direction.

A man with a smiling mask and a Top hat appeared out of the shadows. 

"Why are you here." 

"To see in person how good you are, you know while being quirkless-ouf!" He yells out as I smashed his face onto the floor.

"You know it's funny how much you talk, I'm quirkless yet I can still beat your ass you sly son of a bitch." Sans says with a smirk.

"Heh, you don't even know anything about me, Reaper, the number 1 assassin for the hero safety commission."

"You know it's obvious CAIN, previous number 2 assassin who then betrayed the hero commission and joined AFO."

Taken aback he escapes my grasp standing up again, "how do you know that?"

"I know even more, Cain. Like how you're quirk is immortality."

"Again how do you know that!?" he yells.

"A miraculous amount of recoveries from the edge of death, losing limbs and other."

"That could just be a really good healing quirk of mine."

"Eh, my gut says immortality quirk." I say, "but just in case lets test your answer."

Rushing to him a sharp metal glint indicates that he just pulled a knife, as he goes for a stab I grab him from the hips and bend backwards to smash his face to the ground. unfortunately he puts plants both hand on to the ground as he then uses his feet to smash me into the ground. He has the high ground as he goes a stab I put hand upwards so that the knife goes in between my middle and ring finger, I twist my hand that is now stopping the knife to twist the knife loosening it. I use my other hand to knock the knife out of his hands closer to the edge of the roof as my left hand which was previously blocking the knife was now free as I use it to grab his face.

"UMPH!" His muffled yells protested.

"I'll just keep coming back you son of a bitch." He yells, "I can NEVER DIE!"

"k, I'll be waiting the-oof!" I say as he breaks free of my grasp lunging for the knife that I knocked away.

Realizing what he was going to do I try to get him but he had already got the knife.
