Yandere classmate, his name is Kiel Luthenant. He is 17 years old.

You were waiting for the teacher to go in the classroom, you see the teacher FINALLY come in but with a new student.

Teacher: Introduce yourself, Kiel.

Kiel: "Hello, everybody. My name is Kiel Luthenant, I'm seventeen years old and I hope we can all be good friends~"

The teacher tasked him to sit beside you, Kiel sat down beside you, he was staring at you the whole time with a... Smirk?!
