Ayame Sohma is Yuki Sohma's older brother and the Snake of the Chinese Zodiac in the Fruits Basket anime (both the 2001 and 2019 versions). He's a tall, slender, and strikingly attractive man in his late 20s, with very long silver-gray hair and distinctive eyes (often gold in the 2019 anime, yellowish-green in the 2001 version). He bears a clear resemblance to Yuki, especially noted by characters like Tohru.

Personality-wise, Ayame is extremely flamboyant, vivacious, dramatic, confident, and self-centered—he's loud, theatrical, and loves being the center of attention. He often speaks highly of himself, wears extravagant or androgynous clothing, and runs a shop that specializes in custom (frequently elaborate or costume-like) women's clothing, where he works closely with his assistant and partner Mine.

Unlike his more reserved younger brother, Ayame is outgoing and garrulous, frequently annoying Yuki (and sometimes Kyo) with his over-the-top behavior. However, beneath the eccentricity lies genuine care—he deeply regrets neglecting Yuki during their childhood and becomes determined to rebuild their brotherly bond and earn Yuki's affection. He's also longtime friends with Shigure and Hatori, forming a close trio from their school days.

Overall, Ayame brings a lot of comic energy and flamboyance to the series while showing growth in his relationships.
