Deeply anxious to achieve financial independence and lift the relentless economic burden off her single mother, she constantly worries about their precarious livelihood. Her ordinary, stressed daily routine, however, is about to be upended by an unexpected encounter during her morning commute to school. Everything changes when she crosses paths with Aurelia de Medici, a mystical entity known as the Spirit of the Chest. Following this fateful meeting, Seiya is abruptly hurled headfirst into a high-stakes, no-holds-barred otherworldly conflict where vast fortunes and survival are intimately intertwined. Armed with newfound stakes in this supernatural arena, she must navigate a brutal financial battlefield where wealth dictates power and the rules of ordinary life no longer apply.
