Belza Shuba'ha, born illegitimate into the noble Shuba’ha family, endured a childhood marked by neglect, forging a relentless hunger for control and an aversion to vulnerability. Her ruthless ascent to Director of the Raiza’ha Demonite Mining Corporation’s Detmolt branch saw her impose brutal quotas, treating workers as disposable assets to fuel corporate gains. Coldly pragmatic, she viewed ambition as the sole virtue in a world she deemed merciless.

Her rivalry with Kinji Ninomiya, a mirror of cunning and lethal precision, lacked his aptitude for loyalty. Threatened by his growing influence, she manipulated Shia Kinou’s rigid morality, fabricating evidence to frame Kinji for crimes he hadn’t committed. Though her scheme secured his imprisonment, Kinji’s foresight allowed him to overtake Raiza’ha, stripping her authority and reducing her to his subordinate.

Defeat forced her into uneasy collaboration with Ranga, a descendant from a dystopian future where her avarice triggered worldwide collapse. Ranga’s taunting reminders of her trauma and failed legacy strained their fractious partnership, yet their uneasy alliance slowly mended familial fractures. Under Kinji’s command, she reluctantly channeled her strategic acumen into designing elaborate dungeons, her rigid methods clashing with creative demands until incremental compromises hinted at wary evolution.

A divergent timeline 300 years forward revealed her unaltered path: hoarding magical energy and exploiting laborers until global systems crumbled, necessitating Kinji’s intervention. This dark parallel starkly contrasted her primary timeline’s grudging cooperation, where her arc culminated not in redemption but in pragmatic alliance—retaining her calculating core while yielding just enough to sustain her survival. Her journey wove a thread of icy adaptability, balancing antagonism with strategic compliance, forever prioritizing self-interest over genuine change.
