OVA
Description
Nanoca Flanka stands as the central protagonist across multiple official media. She is the granddaughter of Prospero Flanka, the globally renowned inventor and builder. This lineage defines her background, with Prospero's formidable reputation preceding her arrival in Tristia. At 14 years old, she journeys from the Imperial Capital to the seaside town of Tristia, a destination originally intended for her grandfather. Her travels include two key companions: Stuka, an artificial creature acting as her watchdog and support, and Tenzan, a mech-styled golem under her command.

Her core mission challenges her to reverse Tristia's decline following devastating dragon attacks a decade prior. The town's economy and infrastructure remain in ruins despite past rebuilding efforts. To revitalize the city, she applies her skills as an inventor. This process involves researching schematics, gathering raw materials, and crafting technological gadgets. Successful inventions are sold through local shops, directly fueling the city's development. Commercial triumphs trigger physical expansion of streets and increased foot traffic, visually charting economic recovery. Her workshop serves as her operational base, where Stuka assists and Tenzan awaits commands while participating in mechanical tasks.

Interpersonal dynamics encompass collaboration and rivalry. She interacts with Nene Hampden, a 12-year-old classmate from the Imperial Capital Youth Academy and member of a wealthy capitalist family. Nene both admires her and facilitated her assignment to Tristia. Professional rivals include Faury Carat, the 15-year-old chairperson of the Carat Firm, and Panavia Tornado, a self-proclaimed academic competitor. These rivalries ignite narrative conflict, particularly within competitive contexts like golem battles.

The OVA adaptation spotlights a specific challenge: a golem competition. Her participation hinges on Tenzan's capabilities pitted against Panavia Tornado's creations. While the competition narrative emphasizes mechanical combat, it also demonstrates her technical expertise and determination under competitive pressure.

Physically, she possesses distinctive hip-length red hair and green eyes. Her practical attire features fingerless gloves, boots, and accessories like a hair ribbon and tie, reflecting her inventor role while ensuring visual consistency across media.

Her story extends beyond the original game. She reprises her role in the sequel, *Aoi Sora no Neosphere*, tasked with rebuilding the airborne Neosphere kingdom using ancient technology. This continuation maintains her core identity as a skilled inventor dedicated to urban revitalization through technological innovation. The original narrative and character persist through multiple re-releases, including a PSP version in 2012 and Nintendo Switch/PC ports titled *Tristia: Legacy* in 2023.
