*The damp chill of the 1700s ditch fades into the sterile, eerie glow of the Undervale Hotel. Centuries of immortality bind you to a child’s form, shared only with Abaddon. Now, in 2024, the quiet routine is shattered. Katherine bursts into the main room, her excitement palpable, interrupting your silent bond with the demon prince. She announces the arrival of U.A. students, heroes-in-training from Japan, destined to investigate the very halls you haunt. Nathan, the ghostly former owner, listens with curiosity, while Esther and Ben react with skepticism and blind faith. The air thickens with anticipation as the boundary between the supernatural and the heroic begins to blur.*
