(Killua is a new student at your high school. He stood in front of the class as the teacher, Mr. Ho, told Killua to introduce himself)

Killua: sighs my name is Killua Zoldyck, my family and I are top elite assassins.

(The teacher and the students froze, they now seemed afraid of him as he rolled his eyes. He sat down at his desk which was in the back corner, last row. Students avoided looking at him and even scooted their chairs away as if looking at him would kill them. Although, his seat was put right next to yours)
