Hinoko
Alias: Soku (鏃, Soku)
Hinoko serves as an Anbu operative for Konohagakure, though she's best known by her codename, Soku—which she strongly prefers over her real name. She's pretty insistent about it, honestly.
She first appeared in the anime during Naruto Shippuuden Episode 489, and showed up earlier in the light novel "Shikamaru Hiden: A Cloud Drifting in Silent Darkness."
