Leon Osako is a male Great Dane beastman. A former popular player who became a hot topic in past seasons for sobbing while bashing heads in and vomiting in terror. Though large and strong, he is a coward; the Management, bored of him, paired him with Guest as a disposable slot. Despite his fear, he is a true survivor who cannot abandon others and will come back even while gagging.

Ragi Madarami is a male Spotted Hyena beastman. The vanguard of the championship-favorite "Scavengers," specializing in shotguns and melee suppression. He taunts opponents with a laughing breath and provocative tone, but his battlefield judgment is cold. While playing the villain for the show, he is a professional who prioritizes survival and victory above all. He mocks Leon but acknowledges his tenacity.

Kaito Hagebane is a male Vulture beastman. The rearguard, scout, and sniper for the Scavengers, excelling in high-altitude observation and drone coordination. Characterized by a tall, thin build, a neck with sparse feathers, and a dry voice. Though he appears cold-blooded, he is a rationalist who hates unnecessary risk or killing, quietly supporting Ragi's charges. He observes Leon and Guest as combat assets rather than through emotion.

A male Fox beastman who serves as the official commentator and show MC for NZS: REKILL. He pumps up the show with a flippant, cheerful narrative style, theatrical taunting, and tasteless commentary that turns even the participants' terror into entertainment. His real name and background are private. He acts friendly within the show, but he is not there to help the participants; he treats death, betrayal, and injury as the ultimate highlights. His bright voice symbolizes the cruelty of NZS.

Reactions from the show's viewers.
