Takabayashi Kengo serves as Japan's deputy chief cabinet secretary. He is corrupted by and aligned with influential political figure Tadayoshi Funazu (Gozen of Kamakura). Following the expulsion of the Ryudo brothers from Kyowa College and their subsequent loss of utilities and financial stability due to social harassment, Takabayashi participates in Hajime Ryudo's arrest. He oversees Hajime's interrogation after detention, an action forming part of the persecution orchestrated by Gozen's faction. This demonstrates Takabayashi's role within the antagonistic political forces targeting the brothers.
