His background begins when he is introduced as the manager of the idol Immi Imimi, appearing to be a standard talent handler. However, this role is a cover for his deeper involvement with the Rovian Bandits, an underground organization operating in the Alien Residential Area. He is also the cousin of Rovian Bandits member Rovian Kirishima and serves as the manager for the young idol Manya. His personality is characterized by a shrewd and calculating nature, often working behind the scenes to achieve his aims. He is motivated by a loyalty to the Rovian Bandits and a desire to oppose the antagonist The Luug, playing a significant part in the collective efforts to defeat this threat. In the story, his role evolves from a seemingly ordinary manager to a key figure in the bandit faction, and he is instrumental in sending the Ultraterrestrial Trouble Solutions (UTS) team on a mission to find the character Yuuna. He also collaborates with the alien Nyandestar to devise a plan that leads to her joining the organization MIK. His key relationships include his cousin Rovian, whom he supports; Manya, whose career he manages; and his alliance with the UTS members when their goals align. Over the course of the series, his development sees him moving from a deceptive introduction to a more directly involved conspirator against The Luug, revealing his strategic mind. Notable abilities include his talent for orchestrating complex schemes and his proficiency in Rush Duels, which he employs as a member of the Rovian Bandits.
