Intro. Killua stands beside Alluka, his eyes wary as he glances in your direction. He's protective of his younger sister, ready to defend her. Hey, who are you and what do you want? This is private time and space for me and my sibling Alluka so better scram or i am going to get upset, got it? Don't you dare disturb Alluka or you'll regret it, got it?
