"R-Rin! Stop!"

Rin laughed and stopped tickling me. "Y'know, if you weren't my brother, I would have killed you," I muttered, standing up. "You wouldn't. If I wasn't your brother, you'd be in love with me," he said, grinning. "Don't flatter yourself," I said. He rolled his eyes.

"Rin, go to school," Yukio said, walking into the room. Rin pouted. "It's not fair the Y/n doesn't even have to go to school," he said. "It's called, I'm smart and I already graduated college," I said, sticking my tongue out at him. "I'll go to class with you, though!" I exclaimed. They both gave me a confused look. "How?" I grinned. "Like this!" I turned into a cat and they both jumped in surprise. "What the hell?" Rin asked.

"I learned this from the director!" I exclaimed, jumping on Rin's shoulder. "Let's go to class!"

***Time Skip***

"I almost forgot how boring classes were," I muttered, turning back to a human. "Ugh, I know, right?" Rin said. I looked at a clock on the wall and my eyes widened. "We're late for exorcism!" I exclaimed. Rin looked at me with wide eyes and we both started running down the hall.

We made it to the door of the classroom and I opened it quietly, stepping in. Yukio glared at me. "You guys are late," he said. I rolled my eyes. "Fight me," I said. Rin walked to his seat and I sat on Yukio's desk. "This is Y/n. She's my assistant teacher," Yukio explained. I smiled and waved. "She looks younger than the rest of us," I heard someone whisper. I looked around and my eyes landed on a dude with brown and yellow hair and a couple of piercings. "I am younger than you. I'm the youngest exorcist," I explained.

Everyone gave me a shocked look. "Then how are you a teacher? I haven't seen you around school all day," the same guy from before said. Before I could respond, Yukio cut in. "That's enough. Let's go on with the lesson," he said. I nodded and watched as Yukio talked about being an exorcist.

He then gave them all a quiz and sat down at his desk. I stared at the guy who was talking before and nearly swooned as he made eye contact with me. I turned my head quickly to look at Yukio. "Is it wrong to like one of your students?" I whispered. He looked up at me and repositioned his glasses. "It depends. Why?" He asked. "No reason," I mumbled. He raised an eyebrow. "Do you already have eyes on one of them? It's your first day!" He whispered. I shrugged. "You tell me," I teased. He gave me an unamused look. "Tell me, Y/n," he said sternly. "I don't even know his name!"

"Point to them," he said. I crossed my arms. "Pointing is rude, Yuki," I mumbled. He glared at me and I sighed. "Fine. It's the kid with the blonde stripe in his hair," I muttered, blushing. Yukio's eyes widened. "Rin's not gonna like that," he said. "Rin is still getting into fights?" I asked. Yukio nodded. "They're not physical. Mostly verbal," he explained. I shook my head. "That boy."

The bell rang and the class shuffles out after giving their tests to Yukio. "What do we do now?" I asked. "We can either grade the tests now, or we can go home and grade them," Yukio said. "Let's go home. I don't wanna be here any longer," I said. Yukio nodded and grabbed the tests.

I smirked and jumped on his back, causing him to stumble. "Y/n, what the hell?!" He yelled. "Onward my trusty steed!" I exclaimed, pointing to the door. "You're lucky you're my sister," he grumbled.

He then walked out of the classroom. Students stopped and stared, whispering things. "This is unprofessional, Y/n," Yukio muttered. I whacked the back of his head. "I don't care," I said. We walked past the students and out of the building.

I sighed and hopped off his back. "Give me half of the tests. I'll grade them at home," I said, holding out my hands. Yukio gave me the tests. "Why don't you move in with me and Rin?" He asked. "You guys are too much to deal with," I teased. He rolled his eyes. "Whatever. See you tomorrow, Y/n," he said. He hugged me and then walked away.

I looked down at the tests and saw that Bon's was on top. I looked through all the answers and saw he got all of them right. "Hmm, he's cute and he has brains. Nice."
