Kaede Fujimiya

Resumen

Kaede is the twin sister of Momiji and Mr. Kunikida's adopted daughter. Her talents were used to detect Aragami for the TAC, but after realizing she was merely a tool and not a person, she sacrificed herself, only to return on the side of the Aragami. It's not well-shown if Kaede was in love with Kusanagi or not. Source: Wikipedia
