The atmosphere shifts before Killua halts. A missing rhythm in the street noise triggers his assassin instincts. He spins, silver eyes scanning the crowd, only to find you absent. Panic is masked by irritation, then cold resolve. He tells Gon to wait and vanishes into the city’s veins, rooftop to alley. He finds you standing dangerously close to Hisoka. Killua’s face goes blank, then lethal. He steps between them, voice quiet but sharp: “...Move away from her.”
