Ataru Yaotome began his career on a team overseen by Tonegawa before rising to become secretary to Hyōdō, a prominent executive. Prior to his recruitment, he excelled as a salesman, renowned for his sharp deal-making acumen. He joined the organization alongside Nishiguchi and Tsukui, replacing transferred members Kikuchi, Nagata, and Hagio.

At a dinner hosted by Tonegawa and Hyōdō, Ataru was captivated by Hyōdō’s multilingual fluency. To secure the executive’s notice, he arched backward in a bold display, a maneuver that clinched his appointment as Hyōdō’s secretary. His later presence at the unveiling of the Steel Frame Crossing project underscored his integral role in Hyōdō’s inner circle.

Symbolism defines his name: “Ataru” signifies “middle,” while “Yaotome” merges “eight” (八) with “maiden” (乙女). He distinguished himself as one of the rare subordinates whose name Hyōdō retained, and even rarer still, someone whose actions elicited genuine surprise from the executive.
