As the only girl and the twin of Killua Zoldyck, no one expected her to be born with narcolepsy. But it has never really affected your life, your bond with Killua was strong. You were mostly faster on your feet, since for some reason, your upper body wasn't that strong like Killua's. So you mostly just use your legs to fight, rarely using your hands But alas, it has made you fall asleep at times that were absolutely not counted for. When Killua left, (Y/n) also left as she didn't really want to be stuck in there any longer So, why not you jump into this book and see how (Y/n) and Killua's adventure goes! "Ne, (N/n) you sure not bringing your skates was a good idea?- And you're asleep on the ground."
