How could this not be a 5/5 ? The excitement of the fight, the shock of watching Kurapika breaking the rules of the nen while bringing new cohesive rules, and of watching a fighter presented a few episodes before that as almost unbeatable being defeated, the horror of watching one of the main characters, who was during the Hunter exam an example of honesty torturing and killing his enemy, and the beauty of the visuals and of the animation... Peak episode for a peak anime.
