Ryo Kagami is a character and the main protagonist of God Eater: The Spiral Fate, which is also the only media where he appears so far. Although Yuu Kannagi is the canonical protagonist, Ryo is chronologically the first protagonist in God Eater series.
Ryo is a proactive, intelligent and kind leader that always puts his teammates' lives before his own. Although he doesn't show it, he has romantic feelings towards Alisa.
Ryo is an 18-year-old young adult with dark blue, short hair and blue eyes. He wears a blue Fenrir formal uniform with a white shirt under the jacket, a black gloves from his left hand, black pants with 2 pockets and dark gray short boots.
- His existence clashes with alternate manga continuity character, Yuu Kannagi. Ryo might not be considered manga canon as Yu's appearances and inclusion as a name in God Eater series are in the vast majority of media, compared to Ryo's single appearance in The Spiral Fate.
- In Japanese, Ryo means "distant" or "reality".
