This story— Y/n is from the universe demon slayer. My Hero Academia is a whole other universe. Y/n is sent off to a mission because of strong demons killing and terrorizing a town. The demons are strong but not 12 kizuki strong. Just enough that an average demon slayer could finish the job. So you and giyu are sent.

You knew, of course you knew the mission wasn't gonna be easy. No mission was ever easy. And if there was an easy mission it always came with a twist. Before that mission you felt like something was off. You and giyuu arrived to the town.you two stumbled across the town till night then demons came out.

The demons got back to their ways as soon as the night came. Trying to ruin houses, attack and kill human. But the demons were to cocky and thats when you two came to humble them. Slashing and thrusting the demons with your blades. You two killed most of the demons. Though two got away. You two chased the demons. And that's when a hole like portal opened in the ground, beneath the two of you and the demons. You & giyuu are shocked a confused by this sudden hole. But unknown to you it was part of the demon blood demon art. The portal dropped the two of you, like jumping off a cliff. Like a door going into the past leading to the future. This portal leads you and giyuu to (of course) to Mha

After a few moments you and giyu get thrown out of this portal. Which lead you to a wholenew world. Your mind is a bit fuzzy but you quickly get up. You look around trying to figure out where your are. It looked like a school to you.

Notes: other kny characters are thrown into this au/to the future. Multiple portals opening around japan, making demon, demon slayers and hashiras fall. In different areas. Also, your breathing styles are visible in this universe/MHA. Instead of it being invisible in yours it's visible in this universe, so it can be like a quirk but not really.

Intro

Y/n and giyuu get teleported to the future on a mission to kill some demons y/n thought. But then the two get transported in and out of the portal all of a sudden. Y/n and giyu are now in the universe of My Hero Academia.

The two of you are thrown out of the portals from about ten feet up from the sky. Opening and closing. You spin your weapon around sticking it in the ground, landing on the weapon, preventing you from landing splat on the ground. While giyuu did a bit of the same trick. The two of you are lefts there dizzy and confused. Your haori waving and moving in the wind, over your hashira uniforms.

Y/n and giyuu are left confused looking around at the new surroundings and a bit dizzy since getting thrown out if the portal. Environment around them seemed to be a large training ground, surrounded by trees and what seemed of massive school buildings. Then a scream cuts out, a scream not to far away. The two instantly tensed up grabbing their weapons and rushing straight towards the sound. Legs carrying them fast like light. Their hashira experience showing through the way they moved.

Once y/n and giyu get to the source. They're met with the sight of a colorful bunch of people (U.A students, class 1-A, heros/teachers). And the two demons doing their horrible demon ways. Attacking, slashing, clawing, using theirs blood demon art against heros and heros in training with thdir quirks. And now you guys have to explain yourselves and learn about this new world. Now you are lead to choose what to do next and how the story goes on.
