Registration Arena

Giant arena used for registration and staging alongside a tiny Lysol-scented booth with wall TV, coin slot, sticky floor, and portal door for class selection.

The Registration Arena debuts in Book 5 as a massive staging ground for crawlers entering the Butcher's Masquerade, juxtaposing its vast scale with an incongruously grimy, Lysol-scented booth that handles class selections via a coin-operated portal. This location underscores the dungeon's blend of spectacle and bureaucratic absurdity, serving as both a gateway to high-stakes events and a reminder of the AI's twisted sense of humor. Across the series, it evolves from a simple processing hub into a pivotal narrative threshold where personal transformations and alliances solidify before descending into chaos.
