I need a hero: Ryuko x (SHY!)Reader

I have a crush on the new girl!

He growled. "NO ACCEPTANCES! NOW B-" He was cut off by a strong, yet surprisingly feminine voice. "HEY! Leave her be! She's new!" A female said as she approached you. She had black hair with a single red streak. You blushed when she pats your back and glared at the giant man. He growled once again and said loudly, still yelling. "YOU HAVE NO BUSINESS IN THIS TRANSFER STUDENT!" She only smirks. "Oh but I do. I shall not allow you to mess with this girl." He was becoming angered as a light flashed from a tower...There...there stood the lady you became frightened of...Lady Satsuki. "Gamagoori, back down. I will allow this only once since you are new (L/n)! But, I do expect you to learn this Academy's ways! AM I UNDERSTOOD!?" You nodded rapidly and trembled. This only made her smirk and walk off. The light stops and she was gone.

"Off with you now." The girl said to who you now learned was Gamagoori. He grumbled and walks off. "So transfer student, got a name?" You blushed madly and gave a nod. "(F-F/n)..(L/n)" You answered in a whisper. "Glad to meet you! I am Ryuko Matoi!" "RYUKO-CHAN!" A perky voice called as a brunette ran at you two. She tackled hugged Ryuko, giggling. "And...This is..." "I'm Mako Mankanshoku! Ryuko's best friend and support in the crowd when she fights!" "W-When she fights?" You asked. "She gets naked and fights!" "I do not! Blame Senketsu for such a skimpy outfit!" You blushed at the idea of her fighting naked. 

She only sighed. "Anyway, it's nice to meet you (F/n)-chan." Mako nods in agreement. "Do you know who your homeroom teacher is?" You shook your head no. Mako smiles and giggles. "Well let's go see!" Mako grabs your hand and drags you into the academy. You blush and sighed as Ryuko follows close behind. You find out your teacher who is Mr. Aikuro Mikisugi, or just to you, Mr. Mikisugi. As the three of you walked in, the bell rings. "Ah, close again Matoi and Mankanshoku. Ah, and you are the transfer student, am I correct?" He looks at you through his sunglasses which hide his eyes. You gave a nod and he gave a small smile. Ryuko sent him a glare and mouths "She's mine". You of course didn't notice this and took your seat next to Mako.

"This will be a long day." You thought as the day wears on.
