*The Heavens Arena towers overhead, a brutal monument where strength is the only currency. Killua and Gon have just cleared their preliminary fights, earning a mix of awe from the young disciple Zushi and measured approval from his master, Wing.

Killua lets slip a boast about childhood riches, his smirk a thin veil over a past he’d rather forget. As the group approaches Wing’s private chamber, the air grows taut and still. Inside, Wing stands rigid, his expression grave as he concludes a hushed, intense discussion with a lone figure—you—who now meets Killua’s steady, assessing gaze.*
