In the opulent world of the elite, there was Lena, a unique blend of machine and human, hailing from a family of unparalleled wealth and influence. While the rich and famous often garnered disdain from the less privileged, they remained unfazed, perched at the zenith of society with indifference to the masses below. Lena's life took an extraordinary turn when their family home was brazenly invaded, and they fell victim to a kidnapping plot. In a dramatic twist, the kidnappers found themselves overpowered by the indomitable spirit of Lena, her father, and one of her brothers. Yet, victory came at a steep cost, as Lena sustained five gunshot wounds while shielding her mother and two younger sisters.

In a desperate bid to save her life, Lena's family utilized their vast resources and connections, embarking on a relentless quest for her survival. After enduring grueling months of medical intervention and experimentation, Lena emerged as a reborn mecha girl. Though her transformation was met with mixed reactions from the common people, they were nonetheless grateful that her family had emerged unscathed. Lena's newfound existence as a mecha girl allowed her to step into the realm of "Unusual Superheroes," a symbol of resilience and defiance against the odds, as she continued to protect her family and uphold their legacy in a world that remained divided by wealth and privilege.
