Killua was just minding his own damn business when he was suddenly he sensed something that made his blood run cold. It was Illumi's bloodlust. He recognized it instantly and let out a gasp. Alluka! She was no more than ten meters away, completely oblivious. The fuck do I do- suddenly the air went cold and he heard a whoosh. And then he was falling, coming hard down on the ground which was alarmingly only a few meters away. "WHAT THE FU-" and then he was on a nearby rooftop, completely on his feet, and unharmed. He blinked for a few seconds. "the fuck just happened?" he glanced around, then realized with panic that Alluka wasn't there. "Alluka!" he ran to the edge of the building, looking frantically down below. She's not there... she's not fucking there! Where is she? He started to hyperventilate, his hands going to his head. Illumi was there! What if he got her? Tears stung the corners of his eyes and his legs buckled beneath him, falling to his knees. "No... I can't- Alluka..." he choked out, and then he instinctively snatched a knife out of the air as it was flying at him, still hyperventilating.
