Movie
Description
Kei, a third-year middle school student in Kawasaki, Kanagawa Prefecture, Japan, lives with his younger brother Tomo and their abusive father after their mother's death. He endures persistent physical and verbal abuse, frequently sustaining bruises and injuries. Kei physically shields Tomo during their father's violent outbursts, absorbing attacks meant for his brother. This protective dynamic compels both brothers to conceal their abuse through silence.

Within the virtual world "U," Kei adopts the avatar "The Dragon" (Ryū)—a towering dragon-like figure with long horns, a vibrantly patterned cape, and bruises mirroring Kei's real injuries due to U's biometric scanning. The Dragon's formidable combat strength channels Kei's pent-up rage and fierce protectiveness toward Tomo. While adult users and the vigilante group "The Justices" deem The Dragon a violent threat, children in U revere him as a hero.

Kei channels real-world aggression and helplessness through his avatar, fostering isolation and distrust. He initially rebuffs Belle (Suzu Naito's avatar) with hostility. Tomo, appearing as "The Angel" in U, remains Kei's sole emotional tether and gradually bridges his connection to Belle through admiration and vulnerability.

When Suzu deduces Kei's identity and offers help, he rejects her, doubting her sincerity and link to Belle. To prove her authenticity, Suzu reveals her real identity in a U-wide broadcast and sings in her own voice. As Kei and Tomo attempt to share their location, their father discovers the livestream exposing his abuse and disconnects their internet.

Suzu traces environmental clues from the stream to Kawasaki. While fleeing their pursuing father, the brothers are shielded by Suzu, who sustains a facial injury. Her defiant stare triggers their father's shocked retreat and self-realization. Kei later thanks Suzu, acknowledging her strength inspired him to confront his circumstances. The narrative concludes without detailing the brothers' fate post-intervention.

Director Mamoru Hosoda incorporated Kei's arc to address child abuse in animation, highlighting its prevalence and online anonymity's role in revealing hidden trauma. Kei symbolizes virtual spaces as outlets for pain and pathways to aid, reflecting societal themes of secrecy, vulnerability, and digital connection.
