Itsuomi Nagi

Itsuomi Nagi is a multilingual university student and the main romantic partner of Yuki Itose in A Sign of Affection. Frequent travel has made him curious about languages and cultures, and he becomes interested in learning how Yuki experiences communication as a deaf woman.

Itsuomi Nagi's relationship with Yuki

Calm, direct, and open-minded, Itsuomi approaches Yuki without pity or excessive hesitation. He can seem physically forward, but he consistently tries to understand her boundaries and expands his sign-language skills to communicate more fully.

Language, travel, and learning sign communication

Itsuomi's abilities are linguistic and social rather than supernatural: he speaks several languages, travels independently, and adapts easily to unfamiliar environments. His relationship with Yuki encourages both of them to imagine a broader future beyond their existing routines.
