My name is Shinra Kusakabe… and I'm cursed by fire.
In a world where more than 80% of the population has a Quirk, I'm one of them.
But for me… it was never a gift. It was a disaster waiting to happen.
My power awakened when I was four years old.That day, the flames didn't just appear… they consumed everything.
They were too strong. Too wild. Too alive.
And in a matter of seconds… my entire family was gone.
That's when I met him, My hero A man who wielded flames just like me… but unlike me, he controlled them Where my fire brought destruction, his brought hope.
From that day on, I made a promise I would become a hero I trained. I pushed my body beyond its limits. I fought against my own power every single day.…But even now, my flames still slip out of control.
"Kusakabe, wake up and answer the question." The teacher's voice cut through my thoughts.
I jolted awake, quickly wiping the drool from my mouth"Y-Yes, sir. Right away."
[Later that day]
"Shinra, you want to be a hero, right?" I turned to see a short girl with wide eyes, her tongue slightly sticking out.
"Yeah!" I grinned, placing a hand on my cheek. "I'll prove it… even a demon like me can become a great hero!"" And you, Asui? You want to be a hero too?"
"Yes. I will be a hero. So let's get into U.A. together… kero," she said with a soft smile "And call me Tsuyu. I keep telling you that, but you ignore me."
"Heh… yeah, sorry, Tsuyu. I just get nervous," I admitted, scratching the back of my head, a faint blush creeping in "Well… this is where we split. See you tomorrow."
I waved goodbye and took off running toward the forest Halfway there, I slipped off my shoes. Now it was time.
'The entrance exam is in five days… I have to be ready.'
"My Quirk… Devil Footprint." Flames ignited around my legs, dancing like they had a will of their own "I can generate fire… and even control the flames around me. But the strange part is—my fire only comes out of my legs."
"That's why it's called Devil Foot." The fire intensified "It boosts my speed… lets me move freely through the air… and increases the power of my kicks." I dashed forward and struck a tree.
Boom.
The impact burned a footprint into the trunk
Again.
Boom.
Again.
Boom.
Each strike left behind scorched marks, the forest echoing with the sound of impact and fire "Alright… warm-up's over." I lowered my stance, gathering all my flames into a single point.
The air trembled My legs burned brighter… hotter… sharper. "Let's go…Demonic Fire…" Everything went silent for a split second.
"ADOLLA BURST!" I unleashed everything.
An explosion erupted behind me, blasting the ground apart as my body shot forward like a living bullet "¡BOOM!"
A sonic boom tore through the forest as I broke past supersonic speed. The world blurred.The air screamed. For a moment… it felt like I wasn't even touching the ground.
I landed in a small lake The water hissed violently… then began to evaporate "Damn it… ha… ha…" My legs trembled as I collapsed into the water. "I pushed too hard…"I stared at the sky, my breathing heavy "…Just five more days."
A small smile formed on my face "I'll be ready."

Author's Note:
This version of "Adolla Burst" is not the same as the original from the anime. In canon, Adolla Burst allows Shinra to reach light-speed levels. Since base Shinra can already move at supersonic speeds, this is a toned-down variation.
