Heris Ardebit, chief researcher of the Foresight Foundation, balances scientific precision with familial devotion. As Aina Ardebit’s elder sister, she mirrors her sibling’s fair complexion, pink bobbed hair, and azure eyes, accentuated by round glasses. Her attire—a white lab coat over a dark green sweater, gray skirt, black tights, and white-green shoes—reflects her pragmatic demeanor, occasionally softened by faint facial freckles in artistic renditions. Employed by Governor Kray Foresight, she spearheads ethically fraught experiments on pyrokinetic Burnish subjects to perfect a warp drive for the Parnassus Project. This clandestine initiative seeks to evacuate a privileged few from Earth’s impending collapse, triggered by magma eruptions from interdimensional Promare. Her compliance stems solely from Kray’s vow to secure Aina’s spot on the evacuation vessel. Driven by ruthless pragmatism, Heris subjects Burnish captives to agonizing procedures, siphoning their energy for teleportation trials and fueling the Promatech engine. She coldly justifies their suffering as collateral for Aina’s survival, even deceiving her sister with fabricated claims of Galo Thymos assaulting Kray to obscure Galo’s imprisonment. Betrayal reshapes her trajectory when Kray launches Parnassus without Aina, deploying guards to silence Heris. After Aina exposes Kray’s murder of Deus Prometh and the project’s planetary devastation, Heris retaliates by overloading the engine with Burnish energy, aborting the launch. Fleeing Freeze Force, she allies with Burning Rescue, aiding Galo in rescuing Lio Fotia and dismantling Kray’s regime. Heris oscillates between calculated manipulation of Aina—shielding her with half-truths—and fleeting empathy, notably discomfort at Galo’s abuse. Her technical brilliance surfaces in rapid-fire innovations during the crisis, underscoring her adaptability. Post-conflict, she stands among survivors, her future undefined. Through sacrifice, subterfuge, and eventual rebellion, her arc intertwines familial obsession with a fractured redemption, challenging corrupt power while navigating the cost of loyalty.
