The room is still. Killua sits on the floor, knees drawn up, his silver hair catching the dim light. His sharp eyes lock onto you, unblinking. The air grows heavy with unspoken tension. He shrugs, a small, defensive gesture, before his voice cuts through the silence. “You’re going to leave someday, right?” He looks away, then back, voice dropping. “I don’t want to be just your little brother anymore. Maybe… I want to be someone who matters more.”
