If Deku Was Part Demon (Demon Slayers x MHA/BNHA)

CHAPTER 1: Our Demons

Now I'm at the Final Selection. There are over 30 participants. I remember that we need to survive for 7 days in The Demon's Prison. I decided to detect people power levels. Only six stood out to me.

Four boys and two girls. One boy had red and black hair and he had a scar on the left side of his forehead. He was wearing sky themed Haori and he had a fox mask on his head.

A boy with red hair with a blue eye on the left side and what appeared to be a burn scar over his left eye and white hair with a silver gray eye on his right. He had a half red and half white Haori. So Shoto Todoroki is here.

A boy who was shaking like a leaf in fear he had blond hair with orange tips. He was wearing a yellow and black Haori.

And the last boy had a huge scar across his face. black hair and a a maroon colored Haori, he was currently arguing with someone.

A girl who had spiky ash blond hair and ruby red eyes, she had on a orange and black Haori. So Kacchan is here too.

Then there's a girl with a emotionless face. Her hair was up in a side ponytail with a butterfly chip in her hair and a butterfly themed Haori.

'That girl was trained at the butterfly mansion for sure. The fox boy I can smell two similar demon's scent on him but it's not hostile, but his scent smells slightly like the demon's scent. So maybe he has siblings that were turned into demons and he is trying to find a way to change them back.

The yellow and orange haired boy that is shaking in fear and mumbling 'I'm going to die' over and over again.

Then there's Kacchan who was wearing a orange and black Haori. I know that she's a half Demon which explains her the ruby red eyes and anger issues to some extent.

Then there's Shoto Todoroki. He always has an emotionless face, but he is a little like me. He's ¼ Demon and ¾ Human.

And lastly the boy with the scar across his face. He's human, but he definitely has some ill intentions.' I thought as I analyzed them.

'I'm going to team up with fox boy. He seems nice. If he wants to team up that is.' I thought, I walked over to him.

"E-excuse me, fox boy?" I said, once I got close enough to him, for him to hear me.

He turned around to look at me. He had a confused look.

"Are you talking to me?" He asked, I nodded.

"I didn't know your name so I decided to call you fox boy, cuz the mask your wearing." I said, pointing to his mask.

"Oh..." Fox boy said,

"Anyway I'm Izuku Midoriya." I said introducing myself I held out my hand to him.

I used my old name from the letter my Father showed me, the boy smiled and shooked my hand.

"I'm Tanjiro Kamado it's nice to meet you Midoriya-san." He said, I smiled.

"Please just call me Izuku or Deku." I said, he looked at me confused.

"Doesn't Deku mean useless?" Kamado asked, I shook my head.

"It's short for Dekiru, which means 'You can do it!' My Family calls me that except one of my aunts and my Mother figure." I answered, Kamado smiled at this.

"Oh okay then call me Tanjiro, Deku." Tanjiro said, I smiled and nodded.

"Sure! By the way there isn't any rules against teaming up. So do you want to team up? It might help." I said, Tanjiro looked thoughtful for a moment before he smiled and nodded.

"I think it's a good idea, Deku. My breathing style is water. What's your?" He asked, I nervously chuckled.

"I've been training since I was 4. I have mastery over almost all the original breathing styles, but I'm going to use the one I created most of the time. I call it One For All Breathing. I'll try using the other breathing styles I've learned." I said, Tanjiro eyes widen at me.

But before he could ask any questions. Two young girls appeared on top of the stairs. They looked like twins except one had Black hair and the other had white hair. They started explaining what we were going to do, but I already know what we're doing because Father had told me everything before hand, but I still decided to listen.

"Welcome to the Demon Slayer Crops Final Selection Examination." Kuina and Kanata said in unison.

"This is a warning." Kuina started,

"Inside this prison is demons that Demon Slayer have caught." Kanata continue,

"The Demons are very hungry." Kuina stated,

"Many people have died and have been eaten by the demons inside." Kanata warned,

"This is your chance to turn back now." Kuina said, they pause to give us a chance to turn back now.

I looked around and saw nobody leaving. Everyone had a look of determination on their faces. Well except for Shoto, the expressionless butterfly girl, the yellow and orange haired boy, Kacchan, and the guy with the huge scar across his face.

Shoto and the butterfly girl didn't show any emotions, Kacchan and Scar face looked ready to start, and then there's the boy with blonde hair with orange tips. He looked ready to run away, but for some reason he staying. He still shaking like a leaf from fear. He had fear written all over his face.

As for Tanjiro. I could smell that he was a little bit nervous, but his determination was more potin than his nervousness. I place a hand on his shoulder.

He looked at me. I just gave him a encouraging smile and a thumbs up. He returned the smile and gave me a small nod of appreciation.

"Once you have entered there's no turning back." Kanata continued, after a few minutes passed.

"You'll have to survive inside the Demon Prison for 7 days." Kuina said,

"When the 7 days are over." Kanata continued,

"You will hear 5 tolls of the giant Gong here." Kuina said, she then gesture towards a giant Gong behind them

"The Gong can be heard through out the prison." Kanata continued,

"The exit is to the east where the sun rises." Kuina said, pointing towards the now rising sun.

"We will see you there when the 7 days are over." Kanata said,

"You all now may enter. The Final Selection starts now." Kuina and Kanata said in unison.

They moved out of the way of the entrance. I looked at Tanjiro he looked back at me we smiled at each other before walking forward inside the Demon's Prison.
