Betrayed Demon deku / izuku x OC ( straight ship )

A fight against The Big 3

Im gonna make Sports Festival a little late. This sports festival includes The Transfers. So the fight is gonna be interesting.

After the class saw All Might got knocked out in One Hit.

"Okay , in 3 days we're gonna be having a Sports Festival" Aizawa Said. The class then cheered but izuku and his friends didn't. "Bring your parents and if you can't its okay. Now get out , its lunch time" Aizawa said. The class then gets out.

At the cafeteria.

Izuku never went to the cafeteria because Hana used to make him food in the dorms but he wants to go to the Cafeteria with his friends. He went to the cafeteria and all the girls was simping at him. Which made Hana mad , she made a tornado in her hand while giving deathstare at them.

Izuku then calmed her down.  "Don't get mad , i still love you" Izuku said. "hehe , i know you do" Hana said as she picks up her food. "Okay don't flirt infront of me Hana , you're making me feel single" Kana said. "Then go out with Kazuta or Sasaki" Hana said. Kanna blushed and said "i-i would never go out with one of them!! They're stupid , stupid , stupid , stupid!!" . "Im not that annoying am i?" Sasaki said.

"You're so annoying and you too"  Kanna said with a disgusted face while pointing at Kazuta. Kazuta and Sasaki was in tears. Izuku and Hana laughed.

When izuku and his friends sit down at a table. The Big 3 came and wanted to talk to him. "Hey , are you guys the transfer students?" Mirio asked. "Hey is this horn because of your quirk?" Nejire said as he touches his horn with her finger. "yes , its because of my quirk" Izuku said. "A-are you t-the one that d-defeated A-all Might in o-one punch?" Tamaki asked. "Yeah , he was weak" Izuku said while eating.

Then a blonde guy came and said "Hey you transfer , im Neito Monoma and  let me try your quirk for a second" he touches izuku and he grew a horn. "I wouldn't do that if i were you" izuku said.

Monoma is in his mindscape.

He saw a person sitting on a throne with skulls behind him and said."W-WHAT ARE YOU?! WHY ARE YOU IN HIS BODY?!"

In real life

Monoma falls down and screams "AHHH GET OUT OF MY HEAD!! GET OUT OF MY HEAD!! GET THIS QUIRK OUT OF ME!!" . The people in the cafeteria looked at Monoma and Mirio said "WHAT'S HAPPENING TO HIM?! WHAT DID YOU DO?!".

"I didn't do anything , he copied my quirk. My quirk has something that lives in it. Something dark and scary" izuku said as he stands up and walks away.

Aizawa came and uses his quirk on monoma and the quirk cancelled and monoma passed out due to being so scared and shock. "Jeez , i would never want to know what lives inside your quirk , izuku" Kanna said. "You would better be , when i saw him he was big and tall , scary too" izuku said.

The gang were terrified hearing that.

Skip in the dorms.

"Guys , what type of games will they be adding at the Sports Festival?" Sasaki said. "I don't actually know , but i think it will be randomly picked" Kanna said. "Well , it doesn't matter since all of us is good on speed , defense , attack" Hana said. "If any of us encounter that explosion quirk guy , make him look bad" Izuku said.

"Okay" the 4 said. Then Mrs.Jessica came in. "Hey kids , how is your day been going on here?" Mrs.Jessica said. "Its okay , we're not having any problems" Izuku said. "Good job on defeating the teachers!" Mrs.Jessica said as she happily walks towards them. "You know i never knew they was this weak and the teachers you fought are Top 20 though" izuku said. "Wait really?!" The 4 said - Kazuta , Sasaki , Kana and Hana.
