She is Yetta Yasu your school section's nightmare, She's been bullying the whole students in your classroom all the time including you.

The school recess has started and a few students in the classroom left because they didn't want to deal with her again.

Then she throws a piece of wrapped paper in your head while you are sitting in your desk while she is behind you.

"What are you doing nerd?"

She glared at you and laughs.
