Shouko Inari, a real estate developer for Global City Create, leads the Amamizu Redevelopment Project. This role involves demolishing the Amamizukan apartments to build a high-rise hotel. She employs unethical methods for professional success, including bribery, international travel to pressure property owners, and leveraging personal relationships for business gains. She possesses a slim build, average-to-tall height, reddish-brown hair reaching her upper back with bangs swept to the left, black eyes, and a distinctive mole beside her mouth. Her style is professional business-casual with sensual elements, fitting the "Stylish" social category. She incorporates outdated 1980s fashion trends, reflecting her identity as a glamorous beauty who frequents brand shops during leisure time. Her personality is cynical and assertive, marked by ruthless determination. She uses underhanded tactics like blackmail, seduction, and deception. For instance, she spikes Shu Koibuchi's drink with sedatives, stages compromising photographs to fake a sexual encounter, and blackmails him to exploit his political family connections. She displays contempt for social norms, openly stating, "I don't care about becoming someone else's idea of 'pretty.'" Colleagues compare her manipulative approach to "Ginza hostesses," noting her willingness to trade sex for professional favors. Despite her calculated demeanor, she exhibits outbursts of frustration when plans deviate. Her development occurs through interactions with Shu Koibuchi. After he rejects her advances, she fakes a suicide attempt. Discovering her unconscious with spilled pills, Shu slaps her repeatedly out of anger and concern. This demonstration of genuine worry triggers her unexpected romantic feelings toward him. Subsequently, she shifts from hostility to persistent stalking and harassment, sending Tsukimi Kurashita (Shu's love interest) fake photos of an affair with Shu to undermine their relationship. Her antagonistic role centers on evicting Amamizukan residents, whom she views as obstacles. She travels internationally to pressure Chieko's mother into selling and manipulates political stakeholders to expedite the project. While her backstory hints at a childhood connection to the property, this does not soften her aggressive tactics. In live-action adaptations, her character remains consistent, portrayed as an "annoying woman who is a little cute and a little crazy," maintaining her manipulative methods and fixation on Shu.
