Daiju Mononobe, Seleção No. 1, is a former Japanese bureaucrat turned corporate executive of the ATO Institution, wielding deep political connections. Driven by the ambition to supplant the game’s presumed-deceased creator, Mr. Outside, he seeks to dismantle Japan’s postwar societal framework, which he condemns as complacent due to foreign-dependent economic prosperity. To catalyze national awakening, he orchestrates catastrophic events like the Careless Monday terrorist attacks, believing extreme disruption will rally support for his vision of a self-reliant Japan. In the series’ early stages, he allies with Seleção No. 10, Ryō Yūki, to execute missile strikes disguised as terrorist acts, destabilizing the government while leveraging bureaucratic influence to manipulate public sentiment. When Akira Takizawa and the NEETs counter his schemes, Mononobe pivots, weaponizing agencies like the Public Security Department to target the Eden of the East group. He further challenges Akira’s initiatives by proposing a punitive "100% Inheritance Tax Bill," aiming to strip resources from marginalized communities and redirect them toward his political machinations. Throughout the films, Mononobe escalates his campaign to dismantle Japan’s governance, advocating for an authoritarian regime that sacrifices individual freedoms for state dominance. He systematically targets the game’s infrastructure, destroying mobile supercomputers operated by Juiz to eliminate rivals such as the Supporter and Jintaro Tsuji. His rivalry with Akira peaks in a climactic confrontation where he offers negotiated retirement in exchange for surrender. After refusing, Mononobe’s schemes collapse, culminating in Mr. Outside erasing his memories as the game concludes. Post-memory wipe, Mononobe survives a gunshot by an unhinged Yūki but crashes his car, leaving his fate uncertain. His unwavering ideology frames centralized authority and radical intervention as essential for societal rebirth, contrasting Akira’s bottom-up empowerment strategies. Mononobe’s relentless pursuit of top-down control cements his role as a ideological antithesis to communal reform, underscoring his conviction that national revival demands authoritarian sacrifice.
