S3 You Don't know Us (Kny x Fem!Demon!reader x Bnha)

"Stop lying. Your a demon aren't you."

Rui's mouth stretched into a creepy smile before he started to laugh hysterically, he leaned his head to the side as a shadow casted over his face.

"You really are smart Todoroki-Kun! I knew I shouldn't have underestimated you for your knowledge! You figure everything thing very quickly!" Rui exclaimed loudly.

Todoroki stood there, frozen. He didn't know it was from fear or shock.

"But now you know our secret...you have two options. Become one of us or we'll kill you." Rui said taking a couple steps towards him.

Todoroki snapped out of his trance turned around to run inside to get the pro heroes, but he was stopped someone.

"Where do you think your going boy?" (B/n) said darkly.

"Even If you escape this place alive. You won't be alive much longer after that. You'll die regardless, and even worse. Putting your family at risk." Rui said as he walked closer.

"Become one of us or die." (B/n) added.

"I will never become one of you monsters!" He yelled.

He was about to activate his quirk, but someone covered his mouth and restricting his movements.

"Do you really want to awake everyone else? To make you think that anyone would believe you over us. What a joke." (Y/N) said from behind him.

"I'll be nice. I'll give you to till tomorrow night to decide. If you don't then, we'll use force." (B/n) said then went back into the building. (Y/N) followed him inside.

Todoroki was sweating from what just happened, he glared at Rui before heading inside.

When the half and half boy was gone, Rui got out his phone and dialed a number.

"Hey Tatsuya. You got a new person on your kill list."

The next day both hero classes were training their quirks and their bodies, while Rui was in the forest sparring with Akaza.

"Take a break Rui."

Rui nodded his head before walking away to see (Y/N). "Did you tell him about last night?" The demoness asked her brother.

"Yes. I called him last night after he went inside." Rui said with a smile while hugging her leg.

"Rui. Stop being childish. How old are you?" (Y/N) said playfully.

"I'm three!" Rui exclaimed happily.

-time skip-

"You guys are probably tired from your training! But that doesn't mean you can just make sloppy cat food!" Pixie-Bob yelled towards all the students.

"Your first dish...Curry!" Ragdoll yelled holding up the box of curry.

Soon all the students got to work to make their dinner, even though they were tired. Rui just helped around, he couldn't eat the food anyways.

"Rui can cut these vegetables?"

"Sure." Rui then cut then ingredients with his threads.

"Thank you so much!"

He kind of just sat there on the bench, not really knowing what to do. 'I miss father.'

During dinner, Rui was taken to the side to eat with rest of his family. They couldn't eat human food after all.

(B/n) and (Y/N) finished their food first, and were just chatting with the others. Until (B/n)'s phone rang.

"Sorry, need to take this." He said as he went outside.

Once he knew he was completely alone, he answered the call.

"Hey Touya. What do you want now?"

"Don't call me that. And you know why I'm calling."

"Yeah I'll sent it to you."

"You guys really don't care about the heroes at all huh."

"Tch. The hero system is just corrupted as us. I would say they deserve it. They don't do anything because they want to, they do it for money and fame. While we do it to actually protect our family."

"You have a point. Be sure to say hi when we get there."

"Oh don't worry. We will."
