Gabriela Lotaryńska, a 14-year-old Warsaw native and exchange student in Japan, navigates life with silver twin-tails and a petite 145-centimeter frame. Her childhood shattered at age nine during a home invasion, where a desperate attempt to protect her mother with a stolen firearm tragically backfired, leaving Gabriela haunted by the death she inadvertently caused. She cloaks this guilt in the cryptic label *"Marzanna,"* a silent specter shaping her steely resolve.

Raised in a military family, her father’s influence forged her into a disciplined marksman, renowned for gun-slinging precision in battles against the Clans—manifestations of human subconsciousness emerging from Tokyo’s enigmatic cocoon, the Phenomenon. Though her competitive edge and tactical rigor command respect, glimpses of warmth surface in her loyalty to friends, who soften her edges with nicknames like *"Gab-chan"* and *"Gavi."*

Between skirmishes, Gabriela savors takoyaki and Polish *placki*, collecting kokeshi dolls as quiet tributes to her dual heritage. These simple joys anchor her to ordinary life, contrasting her battlefield ferocity. Volunteering to combat the Phenomenon’s threats, she fights not for glory but to spare others her anguish, channeling grief into relentless vigilance.

Her journey intertwines confronting Clans with confronting herself—slowly peeling back layers of guilt to embrace camaraderie and vulnerability. Team interactions chip at her self-imposed isolation, revealing a girl learning to trust beyond the shadow of *"Marzanna."* The green hue marking her role mirrors this duality: a soldier’s grit intertwined with the quiet resilience of a heart still healing.
