Hinoko is a Konohagakure Anbu. She strongly prefers to go by her codename: Soku (鏃, Soku). Anime debut: Naruto Shippuuden Episode #489 Light Novel debut: Shikamaru Hiden: A Cloud Drifting in Silent Darkness [Spoiler] Background: While she was a student at the Academy, Hinoko invented her own signature technique: the Chakra Needle. Because of this accomplishment, she was scouted by the Anbu and upon graduating from the Academy, was immediately recruited as a member. Abilities: Hinoko is a very skilled kunoichi, supported by the fact that she was scouted by the Anbu while she was still an Academy student. Hinoko is presumably skilled in kenjutsu as she carries a tantou. She is capable of firing chakra needles from her fingertips, which have a variety of effects including paralysing, killing or even energising the target. [/Spoiler] (Source: Narutopedia)
