This is an AU that does not fully follow either franchises and has a number of distinct differences.
Also, this fic will be uploaded in small bursts of 500-1000 word chapters most likely, maybe I'll be nice and give you bigger ones during important events, this is just me trying to find my preferred writing speed.
Also, this fic will start out very similar to My Hero Academia, just with Tanjiro added. But it will eventually diverge and become it's own story.
Quirk: Predator.
His body is far more designed to fight and hunt like an animal, giving him animalistic features such as slitted eyes, fangs, and claws. He is also many times stronger and faster than the average human being and can regenerate wounds rapidly, the maximum healing factor has not yet been recorded.
The only downside to this Quirk is that his stomach is very picky and is unwilling to digest anything other than Raw Meat properly, usually resulting in stomachaches and even vomiting.
Alias: "Demon King"
Quirk: Mutagen.
He is able to heavily modify his own body akin to rapid mutations, he is also able to use this Quirk to rapidly heal injuries. Commonly seen mutations include Tentacles, More limbs, Hardened skin, Sprouting more orifices, etc. This Quirk also gives him great power and speed.
"Demon King" seemingly appeared out of nowhere one day and quickly rose the ranks to become a Pro Hero, Demon King is very well known for his more aggressive form of fighting, usually attempting to land blows that knock the opponent out cold instantly. It's common knowledge he has a private life no one knows about.
. . .
The flap of a newspaper revealed today's headline, "Demon King stops another group of Villains! Will he become number two soon!?", and at quick glance it gave a middle-aged man a smirk that boasted, from within the warped Taisho Period fortress he calls his home he was calmly reading the news like always, making sure to keep up-to-date with how this world operated as he had forced himself to become part of it under a facade of justice.
As he finished the cup of tea that had been placed on a small table next to the man's chair he rose a hand and snapped his fingers, like an immediate response a sliding door nearby opened and one of the man's servants entered the room approaching the man before standing still behind him, "Is there anything I can help with?" she asked in a monotone and dead voice as her black and orange hair rested neatly at her waist, "Just another cup of tea, please." the man answered.
So, the girl took the plate and cup that now emptily stood on the table and began to walk off, before the man snapped his fingers again to halt her, "One more thing, you do know what you'll be doing tonight, yes?"
The girl simply turned to face the man, staring at him with her blanked, pink, slitted eyes that were like a void, "Yes, I do. Under the guise of the villain "Lady Inferno" I will attack a bank with excessive force, you will then arrive and stop me after a short battle. I will then be arrested by the police and when the time is right you will use your Tsuzumi technique to return me to the fortress. Some other servants will then spread rumors that I have an accomplice."
The man grinned, "Very good." he said as he waved to tell the Servant to leave, she complied.
. . .
Meanwhile in one of the city's many butcher shops, the local manager was packing things for his business as a red-haired boy with a notable set of earrings got dressed in his school uniform in the upstairs apartment area.
He was making sure he hadn't forgotten anything as he began descending the stairs, passing by the old manager and waving to the kind man, "I'll be leaving now, see you later!" the boy said with a grin.
"Leaving already? It's like you're leaving sooner every day. Give an old man like me some time to set up the shop before you head out so I can give you a proper goodbye." the manager responded as he placed a large crate onto the ground, leaning on it for a second as he stared at the boy who was heading for school, "Last time I decided to wait around a Villain showed up and completely wrecked the street I was going to take, I arrived way too late!" the boy responded with an urgent and awkward smile to which the manager simply snickered, "You know you'll be excused if that happens, Tanjiro, it's not uncommon."
"I want to give a good impression!" the boy, whom the manager had called 'Tanjiro', responded louder than necessary, "I'll be going now!" he continued before he left completely, the manager waving after the boy as his smile turned into a positive sigh, "He's such a handful sometime."
Around two years ago, the manager had been contacted by an old friend and was informed that he'd need his help, in his words he 'found a kid with a very unique Quick drawback.' and only he was really in a good position to help the kid out, to only be able to eat Raw Meat directly was a huge drawback to suffer especially when your body demands food like his does, so he took the kid in like a son and ever since their relationship grew to the point they're almost like real family.
Kamado Tanjiro.
Age 15.
Quirk: Predator.
Yet no one knows where he came from.
