A World Underneath chapter framed through the perspective of Linkon's Lumiere fan community — the 'Lightchasers' — of which UNICORNS Alpha Team's Nero is the head. The story confirms in-universe canon that the red collar around Xavier's neck is an Evol suppressor, contextualising the suppressor's existence within the fan lore rather than as pure backstory. The chapter likely takes place in the aftermath of Myth 2's Azure Square unmasking.
