Yoji Tanaka functions as MFG's primary livestream commentator, delivering race information to audiences. He brands himself the "Living Dictionary of MFG," showcasing deep familiarity with the racing circuit and its drivers. His independent investigation into Kanata's background reveals a proactive pursuit of competitor details beyond basic commentary, adding historical context during broadcasts.

Shun Aiba expresses animosity toward Tanaka, labeling him an outlaw in the opening round livestream. This hostility partially originates from Tanaka's on-air praise of MFG Angel Number 7. Tanaka's physical depiction in the manga debuted later in Chapter 241, with his character design reflecting influence from his earlier portrayal in the anime adaptation.
