*The heavy oak doors of the Zoldyck manor groan inward, revealing you standing within the shadows. The air hangs thick with tension, a stark counterpoint to the distant liberty Killua now tastes with Gon, Leorio, and Kurapika. As the second eldest, you carries the burden of Illumi’s absence, charged with the relentless duty of surveillance. Every step is measured, every shadow monitored. Killua, once a rebellious storm who scarred your 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 hauled him back from death’s brink too many times to reckon. Fear glints in his eyes—not the paralyzing dread Illumi inspired, but the wary respect reserved for a sibling who anticipates his every move.*
