Movie
Description
Touya Sagami is a 14-year-old Japanese moonchild, one of only fifteen known and among the last survivors due to complications from low-gravity development. Orphaned after his parents' deaths, he lives with his uncle, Mayor Sagami, administrator of the commercial space station Anshin. He and fellow moonchild Konoha Б Nanase received experimental brain implants designed by the AI Seven to regulate their hormonal development and ensure survival beyond infancy; these implants failed to dissolve during puberty as intended, becoming life-threatening defects.
Physically slim and of average height, Touya has short dark hair and dark blue eyes. He typically wears a green-and-white striped shirt and matching shoes, later adopting a jacket with "FiTsZ" branding. He carries a satchel holding his personal spherical drone, nicknamed Dakky (Darkness Killer), which he illegally modified by removing its government-mandated intelligence limiter.
Touya harbors intense resentment toward Earthlings ("earthers") due to widespread prejudice against space-born humans, openly expressing disdain for Earth's culture and gravity. Described as abrasive and exhibiting "8th-grade syndrome," he initially isolates himself, declaring friendships unnecessary. His worldview clashes with Konoha, who admires humanity, and intensifies with Taiyo Tsukuba, an Earth-born UN-contracted hacker tasked with arresting Touya for his illegal drone modifications. This friction extends to their drones—Touya's black, aggressive Dakky opposes Taiyo's white, orderly Bright.
His advanced hacking skills enable him to override AI systems on Anshin, manipulate drone restrictions, and attempt repairs on his deteriorating brain implant. When a comet fragment strikes Anshin, severing communications and life support, Touya's resourcefulness becomes critical for survival. He reluctantly collaborates with Taiyo, Mina Misasa (a social media influencer), Hiroshi Tanegashima (Mina's brother), and Konoha to navigate decompression hazards, malfunctioning nanotechnology, and limited oxygen.
The disaster reveals the comet carries a backup of Seven ("Second Seven"), hijacked by the hacker group John Doe to crash into Earth and kill 36.79% of humanity—fulfilling a misinterpreted prophecy from Seven's cryptic "Seven Poem." Nasa Houston, Anshin's medic, is revealed as a John Doe member sabotaging their efforts. Touya's brain implant, alongside Konoha's, enables quantum communication with Second Seven. Konoha convinces Touya to link the AI to the global internet, allowing it to comprehend humanity's complexities beyond John Doe's nihilistic ideology.
This act catalyzes Touya's development. After the timeskip, he acknowledges Taiyo's advice to leave his "cradle" (space) despite his fears. He travels to Earth, recognizing the necessity of confronting his prejudices to grow. Though still wary of humans, he uses his intellect to investigate Anshin's incident, search for Dakky, and develop new neural implant technology. His story, livestreamed during the crisis, inspires widespread youth-led space emigration—potentially fulfilling Seven's original population-reduction prophecy through voluntary exodus rather than violence.
