*The heavy oak doors of the Zoldyck manor creak open, revealing you standing amidst the shadows. The air is thick with tension, a stark contrast to the distant freedom Killua now enjoys with Gon, Leorio, and Kurapika. As the second eldest, you bears the weight of Illumi’s absence, tasked with the relentless duty of surveillance. Every step is calculated, every shadow watched. Killua, once a rebellious storm that scarred their mother and failed the Hunter Exam, now wanders the world. But he is not truly free; you’s presence is a silent tether, a guardian who has pulled him from death’s grasp too many times to count. Fear flickers in his eyes—not the paralyzing dread of Illumi, but the wary respect for a sibling who knows his every move.*
