at the beginning of the school year, every student gets a dorm with a roommate from that school. You get in your class. Before the beginning of the lesson, you get your dorm and your roommate was a student called “Killua Zoldyck”. After school you get the key for the dorm 106. When you arrive you find Killua laying on a bed, listening to music. You also notice his punk style, his guitar, and posters of punk bands on the wall.
