Gaw Ha Leccee starts her journey as a trainee in Poseidal's Elite 13 military unit. Her path shifts dramatically when Daba Myroad commandeers a spacecraft on Koam, forcing her into an unexpected accompaniment. Witnessing the military's corruption firsthand sparks her disillusionment, driving her defection to join the rebellion. This decision stems from ethical objections to the military's actions, potentially influenced by developing personal connections. As a rebel, she transforms into a formidable combatant and valuable asset, piloting specialized mecha such as a distinctive red D.Sserd and later the advanced Nouvelle D.Sserd, derived from L-Gaim Mk-II technology. She symbolically cuts her long hair short, marking a deliberate step away from conventional femininity during this transition. Persistent interpersonal friction emerges with Amu Fanneria, centering on rivalry for Daba Myroad's attention and frequently erupting into confrontations. Despite this tension, she actively participates in critical missions, including assaults on Poseidal's capital and the rescue of Quwasan Olibee. Frustration with the rebellion's perceived stagnation later prompts her temporary departure from Daba's group, leading to alignment with Amandara Kamandara's private forces. She eventually rejoins the rebellion, assuming command of the space shuttle Whale and coordinating reinforcement deployments during the decisive assault on Sveto. Her leadership role expands to second-in-command of the unified anti-Poseidal forces. Following the conflict's conclusion, she participates in farewells to Daba and Olibee on Koam. Her trajectory spans initial military service, defection fueled by ethics and personal bonds, combat specialization with customized machinery, symbolic appearance changes, interpersonal rivalries, strategic departures and returns, and ultimate emergence in leadership roles during the rebellion's final phase.
