Lost (MHA X HxH)

Killua couldn't move. He couldn't scream, couldn't run, he could only watch. Watch as Illumi stood over Gon, blood pooling around his body. G-Gon... Illumi turned to look over his shoulder for a second, those large black eyes that haunted his dreams stared back at him. "this'll teach you. You'll have no choice but to come back and become the heir Kil" His entire body went as cold as ice. No...No!...NO! Killua woke up with a start, tears streaming down his face and gasping for breath. "GON!" Killua blinked, then his brain registered the hard sidewalk beneath him. He sat up, looking around. He was in what he thought was a neighborhood, houses and roads as far as he could see. It was...a dream? He wiped his eyes, then bit his lip. Where am I?
