Fū Yamanaka

When first introduced, Fū's appearance was that of a regular Konoha Anbu, with a white cloak and mask. When he removed the mask, it was revealed that he was a young man with auburn coloured hair and amber eyes. He wore a short, black jacket with red straps on the shoulders like all members of Root which most likely shows allegiance to the organisation. He also wore a red short kimono under the jacket with a black sash, a pair of black gloves, dark-coloured pants, and regular shinobi sandals. As a child in Root, he wore a light brown short kimono with a black sash, grey pants, and shinobi sandals. Fū also wore black wristbands on his wrists.

In the anime, Fū was among many promising young children from various clans of Konohagakure that was personally selected and recruited by Danzō Shimura to join Root, much to the dismay of Inoichi Yamanaka. His training was directly under Danzō's supervision. Later, already well-adjusted to the workings of Root, he was paired up with the newly recruited Torune. Despite some mild mocking on Fū's part, he was tasked with instructing Torune with the workings of Root. Ultimately, the two formed a strong and long-standing friendship.
