Rin Okumura x Reader.

"Alright class," Mr Okumura started, "we have a new student. Miss L/N. She will be joining you all in training to become an exorcist." I walked to sit at a desk alone when a guy sat next to me.
"Hi! I'm Rin Okumura." He said loudly holding out his hand excitedly.
"Hey. I'm Y/N." I responded shaking his hand. "Now if you'll excuse me, Mr Okumura is starting the class and i'd like to take notes." He walked back to his desk and sat staring at me as I took notes from what Mr Okumura was saying.
"Well that concludes our class. Tomorrow we will be in the gymnasium, I will be assessing your combat skills." I packed up my things and walked back to my dorm. Just as I entered my room I heard the door reopen, I spun around kicking the intruder in the chest. As they struggled back to their feet I recognised them.
"Oh. I'm sorry. You're that Rin kid."
"Y-yeh." He breathed in response. I helped him into my room and sat him on the edge of my bed.
"You should know better than not to knock. You never know what you could walk into." He hung his head in response. He pulled the katana sleeve off his shoulder and placed it onto his lap. Hmm. I quickly pushed him back by his forehead and hooked my foot under the sword and kicked it into my hand. "So. Rin Okumura wants to be a knight." I undid the sleeve and pulled out the sheathed katana. "Is this blade what I think it is?"
"Yes. Give it back! Give it back!" He struggled to retrieve his weapon.
"Kurikara. I never thought I'd see it." He took Kurikara back before I could unsheathe it.
"Yeh well all you do is take notes. Guess you wanna be an aria or doctor or something dumb like that." He laughed smugly. I reached into my wardrobe pulling out a bow and quiver of arrows.
"Tamer and dragoon, actually. My familiar happens to be a bird-like demon which helps with my mastering ranged weaponry especially archery. Still think you're better than me?" I pulled the katana from its sheath, held by Rin. His body erupted with blue flames. "Well. Son of Satan? Think you can take me?"
"W-what? How did you?" He paused momentarily. "You're a full exorcist aren't you?"
"Yes, first class. Ive been sent to watch over you Rin Okumura. Make sure that this," I said gesturing to all of him "never happens." Those beautiful blue flames leapt from his body, his ears, longer and elven. I could now see his long black tail, tipped with thick black hair.
"You gonna gimme my sword back or not? Or you just gonna stand staring at me."
"Just taking in what I have to work with. You're pretty cute for a demon."
"You're not bad for someone who lies about who they are."
"You're one to talk son of Satan. Hiding who you really are."
"Touché." He smiled. His white fangs, shining in the light of his flames. I stepped forward placing the katana back in its sheath. I placed my weapons back in my wardrobe and rolled up my sleeve to reveal the pentagram tattooed on the inside of my wrist.
"Harder for people to break the circle eh and easy for me to activate with blood." He nodded. I moved forwards again until I was sat face to face with him, moving closer still.
"Oh my god Y/N!" My room mate screamed as she walked into the room. I quickly grabbed Rin's tail holding it to my bed and under a pillow.
"Hands off the tail!" Rin whispered, blushing.
"Who is he and what is he doing in our room?!" She said still screaming. I leaned closer to Rin.
"She's not an exorcist and knows nothing of the two worlds. Play along." I turned back to my room mate. "We are together. I should've told you. That's where I keep disappearing to. Sorry Kika. We didn't think you'd be back so soon did we babe?" I slipped my hand under the pillow and wrapped the tip of his tail around my finger. He gasped lightly and his blush only grew.
"N-no. Ever so sorry." He stammered.
"Rin. How about we go back to your room? Leave Kika to do her studies. He slightly lifted his shirt, wrapping his tail around his torso out of sight. We both stood up and walked back to his room only to find Mr Okumura sat at a desk.
"Hey Rin. Where have you been? You look rather flushed are you okay?"
"No. Someone knows how sensitive my tail is and is using it to her advantage." His blush only deepened when I wrapped my arm around him, again finding the tip of his tail.
"So. You know who she is now. I think now is a poor time to tell you she's a bit of a flirt."
"Yeh. Thanks for that Yukio." He pulled out of my grip and sat on his bed. I walked over and draped my arms over the younger brother.
"Why is he playing hard to get Yuki? Others just fall at my feet."
"Maybe he just doesn't like you Y/N. No one has ever touched his tail like you. Maybe you scared him off." He laughed at me. "You do come on rather strong."
"Most other exorcists love that kinda thing. Ohhh. That's right. He's not an exorcist. Maybe that's why, maybe he's just not up to the challenge of me." I smiled looking slightly at Rin. "Oh well. I guess I'll just have to leave, he'll just have to learn how to fight himself."
"Wait!" He said with a hand extended. "If you're here to teach me then I wanna learn and I can take you, I've just never had a girlfriend." He mumbled the last part but I heard. I walked over to him, taking his chin in my hands. His face was pure shock.
"Would you look at this I've scared the son of Satan. Oh boy, I will teach you so much more than fighting." I said with a smirk.

Yeh I know it's not all that but I love Rin. My little demon child.
