Jintaro Tsuji, designated Seleção No. 2, collaborates early with figures like Daiju Mononobe and Ryo Yuki in the game orchestrated by Mr. Outside. He sports a distinctive toque and maintains a detached demeanor, prioritizing a swift end to the competition over active investment in its goals. Notably, he asserts he has withheld spending any of his allocated 10 billion yen, hinting at either calculated restraint or ambivalence toward his role.

Later, Tsuji pivots to manipulating public perception of Akira Takizawa, circulating rumors framing him as both martyr and terrorist. He propagates the claim that Takizawa is the illegitimate son of the late Prime Minister Iinuma, seeking to sway societal sentiment and manipulate the game’s trajectory. These efforts align with broader strategies by factions within the Seleção to undermine Takizawa’s standing and steer the competition’s outcome.

Tsuji further targets the game’s infrastructure, focusing on mobile units housing the Juiz supercomputers. During clashes over control of these assets, Mononobe destroys his truck, severing his direct link to Juiz and sidelining him from active gameplay. This elimination highlights his role as a secondary antagonist whose maneuvers, though persistent, remain peripheral to the central power struggles among the Seleção.

His documented involvement centers on tactical alliances and psychological manipulations, reflecting a pragmatic approach to influencing the game’s progression while avoiding direct confrontation.
