Gii reigns as the primary antagonist within KOHATA Anime Studio's fictional anime production. Known fully as Gi Tata Oota, he embodies an evil wizard locked in perpetual conflict with the protagonist, Coco Lily Frau, constantly striving to sabotage her endeavors. This defines him as the central villain within the studio's fantasy world.

During the story involving Baja, Gii materializes one night to attack Ga-chan, the duck floating in the studio's pond. This nefarious act directly ignites Baja's quest to rescue his friend. Gii wields the power to manipulate reality, demonstrated by his ability to animate inanimate objects like the duck toy. His presence introduces potent conflict, challenging Baja.

His motives arise solely from his inherent role as a villain in this fictional universe. He consistently opposes Coco, reflecting a classic antagonistic dynamic. Targeting Ga-chan exemplifies his established function: creating obstacles for protagonists. The character exhibits no significant development or layered complexity beyond his antagonistic purpose.

The narrative frames Gii exclusively through Baja's perspective, where he is perceived as "a very evil Wizard" and a direct threat. This viewpoint solidifies his role as a pure source of conflict, devoid of nuanced backstory or redemption. His actions remain tethered to driving Baja's magical journey forward and underscoring themes of courage through opposition.
