Prologue

"Hey…don't do it."

Midoriya almost didn't hear those four words calling out to him. It was so soft, almost inaudible. It could have easily have been masked by the wind, if there had been any blowing about on the rooftop at that moment.

But there was no wind, and Midoriya heard the voice.

He turned back. His eyes met soft, blue ones.

"W-Who are you?"

By this stage of his life, Midoriya Izuku probably had gone numb to how the day will most likely play out. He will go to school, get whispered at by his schoolmates, bullied and beaten up by Kacchan and his lackeys, return home, have dinner, finish his homework, shower and then go to sleep. Only to wake up the next day to repeat the cycle all over again.

And it has been like that, slowly deteriorating, ever since he discovered that he was quirkless. From the young, tender age of five, until his adolescence, Midoriya had gone through far too much for a young person his age.

Things got to a head, when just hours before, Kacchan had destroyed one his notebooks, thrown the remains out of the classroom window. To add further insult to injury, the explosive blonde had told the shaking Midoriya to kill himself if he so desperately wanted a quirk. The final blow came, when out of all people, All Might himself said that Midoriya couldn't be a hero because of his lack of quirk, after saving him from a slime villain that almost did him in.

After All Might left, leaving Midoriya alone on the roof, he almost laughed at the irony of what his childhood playmate had so heartlessly told earlier in the day. Here he was, standing on the rooftop of a random office building, just a few paces away from the railing, and certain death beyond that.

There was a time, long passed, that Midoriya wouldn't even give suicide a thought. But years of pain, torment and suffering had corroded his will to survive. Even thoughts about his mother, his only blood relative, and his most ardent supporter since young, wasn't enough to stop the poor soul from stepping towards the railing, the last bits of his will to live fading away with each step.

'Maybe…Kacchan is right.'

Midoriya let out a sniffle, as his feet reached the base of the railing. It was the only obstacle preventing him from taking his own life. But what can an inanimate object like a railing do for Midoriya? Stop him from climbing over?

He almost laughed at the thought.

A gentle gush of breeze blew across the roof. The sun continued to shine its daily rays upon the world, in its place in the blue sky accentuated with clouds.

'Okāsan…I'm sorry.'

Midoriya steeled himself. His right foot left the rooftop floor, finding a spot on the railing. With another breath, his left foot joined the right. He is now standing on the railing. All it needed was for him to climb over, and to let go.

But then…that voice came.

"Hey…don't do it."

Now we see Midoriya staring in surprise at the person with blue eyes, who appeared to be wearing a school uniform consisting of a white blazer, light-blue dress shirt, and black slacks and tie. He has matching blue/teal-colored hair that fell over his eyebrows and ends short on his neck. His lips are drawn in a neutral, expressionless line, but the eyes are silently pleading. Don't do it, as with what he uttered moments before.

The caution button is immediately pressed in Midoriya's mind. He knew he was alone on the rooftop, and he would have heard if someone else came up here. So…who was this boy? What did he want? Why is he trying to save him?

"W-Who are you?"

"My name is Kuroko Tetsuya. Please don't climb over that railing."

"Why s-shouldn't I?"

"I can help you."

Those four words, pronounced over a monotone voice, immediately chips away at Midoriya's will to end his life. Further erosion comes when Kuroko brings his arm up towards him, extending a hand as if to say, "Trust me. There is a way."

Midoriya glances down towards the road below. It is a long drop; the height would have certainly killed him even before he reached the ground. And it certainly wouldn't be a pleasant sight for the innocent people walking along the pavement below to see a body break irreparably in a pool of blood on the pavement, even worse if he landed on someone and killed them too.

"You don't have to resort to this."

Midoriya glances back towards Kuroko, who is now standing less than a pace away from him. The green-haired boy couldn't put his finger on how the tealnette could have walked over without making a sound. But with Kuroko's eyes now burning with pleading insistence, and his outstretched hand just an arm's length away, Midoriya made his decision.

His left hand, grasping the railing, pulled away. Midoriya then reached forward, and took Kuroko's hand.

Hey guys, hope you enjoyed the prologue. I was inspired to create a BnHA x KnB crossover based on Midoriya becoming a vigilante. This story will follow some aspects of the BnHA canon timeline, and Kuroko's backstory is more or less the same, with adaptions to the BnHA storyworld.

Please leave reviews, I really appreciate feedback to hear what you guys have to say and your opinions on what can be improved or how the story is progressing.
