Kaede Fujimiya  

Kaede Kunikida, Kaede Kushinada, 国木田 楓

Kaede is Momiji's twin sister and Mr. Kunikida's adopted daughter. She possessed abilities that allowed her to detect Aragami for the TAC, but after realizing she was just a tool and not an individual, she made the ultimate sacrifice by giving up her life. Despite this, she later returned as an ally of the Aragami. There is no clear indication whether Kaede had feelings for Kusanagi or not.
