A Bount who served as Jin Kariya's right hand, Ugaki preferred working behind the scenes rather than jumping into fights himself. When he did release his doll, he'd typically hang back out of sight. He's best known for his role in helping Kariya develop the bitto after Yoshino Sōma's death—a project that shows his technical skill and loyalty to the Bount leader.
Appearance-wise, Ugaki fits the look of a corporate type: white button-up shirt, tie, large glasses, and neatly combed hair. It's a stark contrast to the more destructive side of his work, though it probably helped him blend in when needed.
