Takumi Kuruya is a 23-year-old informant operating in Tokyo's Shinjuku Ward, often connected to the freelance agency Youtoukorou and a former member of the gang Sons of the Styx. He stands 170 cm tall, sports short brown hair, bears multiple scars on his back, and almost always wears black-purple-and-white VR goggles that charge via sunlight or electrical outlets. His typical outfit is a one-shoulder black tee with white stripes layered over a black tank top, paired with shorts and flip-flops; he sometimes adds black headphones with green accents. Takumi initially valued his personal safety and lifestyle above societal laws or others' lives, engaging in illegal drone surveillance and aiding contract killers with corpse disposal. He readily admitted to betraying friends under pressure, exemplified by his tearful cooperation with detective Gōzaburō Arase after witnessing the massacre of eight Sons of the Styx comrades—a betrayal driven by terror, not calculation. Despite this self-serving past, he later showed a willingness to protect allies, offering to "take the rap" for illegal drone activities to shield Misaki Sakimiya and the Corpse God. His background reveals a former "boy genius" who founded his own software company at fourteen, only to have it usurped by adults. Surviving a forced double suicide attempt, he entered the criminal underworld, using his technological expertise to survive. His skills include deploying drones for data gathering, hacking security cameras, and real-time situation analysis. He operates a server farm maintaining a surveillance network across Shinjuku, often acting as the logical, practical "voice of reason" alongside the Corpse God and Misaki. He exhibits occasional eccentricities, like sentimental attachment to his drones or delight in conceptualizing himself as an "identification wizard" through data collection. Key events saw Takumi observe Polka Shinoyama's inexplicable survival via drone footage, prompting him to cancel body cleaner retrieval. He later witnessed Misaki Sakimiya's impalement by the Corpse God's skeletal hand, initially doubting his sanity before verifying the supernatural event. When the Corpse God intervened to rescue children from a fire, Takumi guided him via drone while questioning his inconsistent ethics—contrasting his lethal treatment of Misaki with his lifesaving actions. After the rescue, Takumi expressed frustration over viral images of skeletal hands and warned Clarissa against further involvement with the unpredictable Corpse God. He was subsequently assigned as the Corpse God's companion under Clarissa's directives, assisting his fortune-telling business by gathering client information. Takumi's technological skills and surveillance network proved vital for navigating Shinjuku's criminal landscape, tracking threats, and coordinating responses. While maintaining a pragmatic outlook, his interactions with the Corpse God and Misaki gradually drew him deeper into their operations, balancing his self-preservation instincts with emerging loyalties.
