Puria Richardson operates as crew member #23 aboard the Daiku Maryu. Starting with a confrontational and abrasive demeanor, she frequently clashes with other crew members, especially protagonist Daiya Tsuwabuki. Their dynamic evolves over time into a vitriolic yet mutually respectful partnership.

Her primary role is piloting the Stinger support craft, where her exceptional skill earns her recognition as an ace pilot. The Stinger receives significant technological upgrades early on, integrating a Despair Sight system for enhanced combat. It later undergoes a comprehensive overhaul, transforming into the Superior Stinger. This upgraded unit gains the critical function of replacing Gaiking as the Daiku Maryu's primary head during specific operational phases.

Demonstrating versatility, Puria participates in auxiliary units that combine with Gaiking, such as Sky Gaiking, contributing to combined tactical maneuvers in battle. Her mechanical expertise contrasts with her formal appearance, where she wears elegant ball gowns instead of her usual practical attire.

Personality-wise, Puria embodies a tomboyish attitude with underlying tsundere tendencies, often masking genuine concern or camaraderie with outward hostility, particularly toward Daiya. Initially dismissive and prone to pranks, her conduct gradually softens through shared experiences and frontline combat. She develops a complex mentorship role, balancing her competitive spirit with a growing sense of responsibility toward the crew's objectives.

Her combat effectiveness remains consistently high throughout the series. She transitions seamlessly between piloting the Stinger/Superior Stinger and participating in Gaiking's combination sequences.
