In Otaranger uniform, he wears his sentai-colored tracksuit while half-donning a handmade ota-ranger helmet halfway covering his face. It is assumed that he is of African origin.
Like Otacross, he was obsessed with beautiful ladies and try to fawn over Jasmine Alexander.
Though when in battle, he is quite strong but his overreacting personality over something trivial leads to his lost, just like the other OtaRangers.
Otacross explains that he and Ota Gold are two new recruits to the Akiba Sentai OtaRangers that recently joined. In the waiting room, he watches as his teammate Yujin discusses with fellow competitor Ban Yamano after the introduction to Artemis 2051.
Alongside his fellow OtaRangers, they reach the finals of D Block. In the finals of the Artemis Tournament, he's chosen after he wins a rock-paper-scissors contest between him, Ota Red, and Ota Silver. He was very pleased to meet Jasmine Alexander and tried to win her over. Even in battle, he made his LBX present known for her Amazoness, which ignite her seriousness. Bibinbird Gold managed to damage Amazoness leg and causes Jasmine to get angered further, chasing and cornerning Ota Gold's LBX. In the end, he loses against Jasmine upon fleeing. Just like the other finalists, he was also shocked to learn that Asuka is a girl rather than a boy. Afterwards, Ota Gold had very minor appearances. He was only seen carrying LBXs that Otacross bought with Ota Silver and Ota Red and saddened over their lateness to arrive on time for Cosmic Pretty Reina's limited edition figure. He was also one of the players to send their LBXs data to Tiny Orbit in order to create an LBX that surpasses O-Legion and involve in the Grand Sphere plan.
- Ota Gold's design comes from the Super Sentai inspiration, as the Gold Ranger additional/sixth member.
- Prior to his identity, his color theme is bronze gold.
