Hisoka has a sister? Who would've guessed. Y/N takes the Hunter Exam with her older brother Hisoka. In this AU Y/N is 16 and Hisoka is 20. (I know Hisoka is actually 27) Y/N is 4 years younger than Hisoka. Hisoka cares a lot about his little sister. He's a big softie for her. Hisoka would kill anyone/anything for his dear sister. His sister is an insomaniac so she sleeps a lot during the day.
