The man who sold the world ]JJBA X BNHA[

Prologue

Smoke settled as Shoji surveyed the training area. He had just taken a major beating from Y/N, but him and Todoroki together could stand a chance. He saw a silhouette rise from the smoke as him and his partner stood side by side in a battle ready stance.

"Wryyyyyyyy" the silhouette hissed as it stumbled forwards

"Dont worry." He turned to Todoroki whilst he spoke cool and calmly "I will defeat him." The six armed boy turned back to the silhouette, piercing red eyes shining through white smoke, its menacing presence palpable in the air.

"Wait!" Yaoyorozu, their enemies partner, burst into the room, perhaps in an attempt to save them from the monster in front of them "Y/N's quirk! His secret ability! He can stop ti-!"

"ZA WARUDO!"

9 months prior.

Before we can get into the cunning exploits of Y/N 'Dio' L/N, and the absolute beatdown I have set up we must first start at the very begining. For the sake of this story, Your British (welcome to the club) and that is where we shall start. It was a cold, dark September morning, rain pelted windows and beat down on weary passers by. Just like every other day, Y/N was sat in his dingy broken down apartment, the walls blistering to reveal the bone yellow drywall that was being eaten by mould. The shredded armchair he rested on held together by stitches he sewed on.

Y/N, despite his current circumstance and lack of education, was a highly intellectual child, taking books from wherever he could get them and learning from them. Sewing being one of the skills he had acquired. Not only was he mentally spectacular, he was more so physically due to his quirk. On his legal records, it was stated as "Ultimate Lifeform" Though the words tasted vile on his tongue, so the boy referred to it simply as vampirism.

If you hadn't watched JJBA, or havent guessed why this brilliant child lays destitute in some decrepit alley house somewhere in London, it was due to his father. The man was a large, beer bellied, bulbous alcoholic. Due to lack of upkeep on his body, not even his quirk could keep him in a fit shape, his eyes bulged from his eyes and his wiry grey hair sprang out like a bristle.

The man laid in the corner of the room on their only bed, cans and bottles surrounding him. He shakily heaved himself up so he could sit facing his son, a cacophony of coughs forcing their way from his throat "Oi! You worthless brat!" The mans coarse cry forcing Y/N to look up from his novel "Go to the fuckn store and get me something for this bollocking cold!" The boy placed a bookmark in the leather back and closed it.

"And what medicine would you have me buy Father." The word father felt like acid burning through his tongue, he was no Father. He was no man. He was a pathetic mess that he would surpass and piss on his grave when he  finally kicked the bucket.

"BAH! Their snake oil wont do me any good, boy! I need booze!" The younger L/N groaned, causing the bed bound to throw a glass at the wall beside him "NOW YOU BRAT! THERES A FIVER ON THE TABLE!"

The fact that this was related to him in any form irked him beyond all hatred on earth. The thought of his fast approaching death and the great escape to a nearby hero school delighted him, and it never left his head from his quick journey to the shops, earning a few racist remarks from his dad.

Two weeks later.

And finally, he was knocking on deaths door. The man had grown fatter, his eyes bloodshot and teary aswell as red blistering skin "Listen here you insolent welp, this" he held up a poorly written letter "is your blasted ticket out of here. You go and find a man in Japan called Yaoyorozu. Damn fool thinks he owes me. You go and you take the rich bastard for everything he has." The 14 year old took it and left, never to be seen by his father again.
