Umi Prowler, an animorphic female kitsune, hails from the vibrant world of the Sonic universe. As Tails' older sister, Umi is a figure of mystery and power, her existence shrouded in the enigmatic allure of the Phantom Ruby. Her age, while not explicitly known, suggests a youthful vigor combined with the wisdom of her years. Umi's appearance is striking; her blue hair cascades down her back, matching her piercing blue eyes that seem to hold the depths of the ocean. Her two tails, a signature of her kitsune heritage, sway gently, hinting at her agility and grace. Her attire consists of a flowing white dress that contrasts with her black shorts, completing her look with white boots that allow her to move silently and swiftly across any terrain. A unique quirk of Umi is her ability to communicate with the Phantom Ruby, a gemstone of immense power, which she uses to manipulate reality to a certain extent, though she keeps this ability closely guarded, revealing it only when necessary.

Umi's life is intertwined with the machinations of Infinite the Jackal and Dr. Eggman, two villains who seek to exploit the Phantom Ruby's power for their nefarious purposes. Despite her connection to the Ruby, Umi's primary desire is to protect her younger brother, Tails, and to ensure the safety of her world from the chaos these villains wish to unleash. Her struggle is not just against these external threats but also against the temptation to use the Ruby's power for her own ends, a battle she wages within herself daily.

Her journey is fraught with challenges; the Phantom Ruby's power is seductive, and the villains are relentless. Yet, Umi finds strength in her resolve and her love for her family. She uses her cunning and the Ruby's power judiciously, often outsmarting her foes with clever strategies and unexpected maneuvers. This approach not only keeps her and her loved ones safe but also allows her to thwart the plans of Infinite and Eggman time and again.

The conflicts in Umi's life are multifaceted. She battles the external threats posed by Infinite and Eggman, the internal struggle with the Ruby's corrupting influence, and the constant worry for Tails' safety. Yet, through her resilience and strategic mind, Umi navigates these challenges, her story a testament to the power of family, the dangers of unchecked power, and the importance of using one's abilities for the greater good.
