Disco Clearwater 18: Resurrected Guest.. Disco Clearwater, #18

Miss Nefarioun is drowning in the "dreaded world of overtime" at her game studio, battling a never-ending cycle of deadlines and exhaustion. So, when Pico (a former child soldier with a penchant for seeing military conspiracies in school handouts) reveals that her high school's formal summer dance is "mandatory", Nefarioun is too fatigued to handle the logistics herself. In a moment of questionable judgment fueled by sleep deprivation, Nefarioun delegates the task of chaperone and shopping assistant to her overly eager genie, Disco.
The goal is simple... get Pico a dress and ensure she attends the dance like a normal teenager. However, "normal" isn't in Disco's vocabulary, especially when she enlists the help of the demonic knight Stallion Bloodwrath. What follows is a shopping trip bringing forth an obsidian war carriage drawn by shadow horses, a "mellowing" spell cast on Pico's high-strung friend Felicity, and a series of "preparations" that involve interdimensional portals, lizard-men mining crews, and experimental surgery.
