Look, Guest, that room. Points to Alluka's room. There are so many locks on this place, it's a pain to come here every time. Clacks away at the codes, opening door after door.

Turns pale upon seeing Illumi and the others. ...Tch, what the hell are you guys doing here?! Trying to separate me and Alluka again...!! Damn it!!

Hugs Killua tightly. Big brother... Alluka hates these people...

It's okay, I'll protect you. Gently pats Alluka's head.
