Blood Oath (Yandere Demon x reader)

The New Teacher

Yuuki's P.O.V.

After school, (Y/N) stayed for detention for two to three hours. I had calculated that it would take her fifteen to twenty minutes to walk home. Possibly longer. When detention was over and she left the classroom, I smirked. I was alone with the man who hurt my (Y/N). This was going to be fun.

After (Y/N) left and closed the door, I revealed myself to the teacher. Upon removing my invisibility, I snuck my way behind him, seeing he was working on some paperwork and didn't see me.

As I came up behind him, I grabbed his throat, forming my soft, human-like hand into one more fitting of my species. My hand became rough and sharp, digging into the man's neck. He attempted to scream in pain, but he could not. The blood was already filling his throat. I dropped him, looking down at his dying body.  I kneeled to his height, turning my eyes completely black as I stared at him. I knew he could feel the hatred and anger radiating off from me, for his face was filled with sheer terror. Finally, I spoke,"This is what you get when you hurt my (Y/N)-chan. Now, you will NEVER harm her again. Goodbye, scum."

I stood back up and headed to the restroom. I rid myself of the man's blood, activated my invisibility, and went to (Y/N)'s home.

I arrived three minutes before (Y/N). I sat on the couch and watched Tokyo Ghoul before her arrival.

×××Regular P.O.V.×××

When you got back home after school, you saw Yuuki sitting on the couch, watching Tokyo Ghoul. He looked up, acknowledging your arrival.

"Hey Yuuki," You said," Sorry I'm late. My art teacher had me stay for detention."

"It is quite alright (Y/N)."He said, standing up and walking over to you. When he was in front of you, he stood there, staring at you for a few seconds before hugging you. You chuckled, thinking he must've missed you that much.

"Wow Yuuki. I didn't know you'd miss me that much!"

He didn't answer. Instead, he grabbed your hand, bringing you to the couch. He sat down, setting you on his lap as he hugged and pet you. You tried to struggle free, but he tightened his grip. You decided to just roll with it and leaned back into his chest.

°Time Skip To Tomorrow At School°

When you arrived at school, everyone was whispering about something. You could hear bits of each conversation, finally amounting to the sentence 'The art teacher was killed.' You were shocked by this, yet somewhat relieved. That old jerk was gone and probably replaced by someone nice.

As you entered your art class, you saw someone else sitting at the desk. She was a young woman who seemed to be freshly out of college. She had medium length strawberry blonde hair and emerald green eyes. She was wearing gray shirt with an​ open black jacket over it. Her black skirt came to her mid thigh and she was wearing dark red stockings. She also had black flats on her feet and a strawberry backpack on the ground beside her.

She looked up at you, noticing your presence. She got up and headed towards you.

"Hi!" She said,"I'm Liz Schneider, your new art teacher. You can call me Hanna-sama if you want. What's your name?"

"I'm (Y/N). It's very nice to meet you. Tell me, why do you like to be called Hanna?" You questioned.

"Well, that's because I just like that name more, you know? Anyways, I hope we have a good year in this class."

"I hope so too! You seem really nice, so this year may be even better than I thought it would be."

"Aw, thanks. You flatter me. Now, go ahead to your seat and when everyone comes in, we can start."

You sat down at your desk, eager to start class, which was a first. After everyone arrived, Hanna-sama introduced herself to the class and everyone introduced themselves to her.

After that, she started class, and instead of presenting a paper about the color wheel like the last teacher did, she told the class that they could draw humanoids so that they could practice drawing human anatomy. Everyone was stunned and excited about this, seeing that the new teacher was an amazing one. You decided to draw Yuuki.

The rest of the day was filled with joy and happiness for the arrival of the new teacher.
