In an unexpected turn of fate, you face the end of your life and awaken in a different world. You die, possibly in chaos or calm, only to be reincarnated into the body of Metal Sonic—not as cold machinery, but as a fully fleshed Mobian. This realization is both thrilling and bewildering as you embrace new sensations and emotions.

Determined to carve out your own identity, you search for a suitable name, eventually choosing "Swift the Hedgehog." It feels fitting, embodying your newfound agility and spirit. As you discover your memories, you learn you are 15 years old, navigating this vibrant realm.

Initially, you find yourself captured by the infamous Dr. Eggman, but your determination allows you to escape. This leads you to the enchanting Kazu Kingdom, a mysterious realm hidden from the outside world.

Exploring Kazu Kingdom, you form deep friendships: Mason Pillar, an adventurous 11-year-old fox; Luke the 16-year-old echidna, a dedicated warrior; Emilia Thorn, a spirited 13-year-old hedgehog; Sarah the compassionate 14-year-old hedgehog; Solaris the Hedgehog, a wise 16-year-old; and Bunix, an energetic 9-year-old rabbit. Together, you navigate the challenges of youth and build a strong bond.

Years pass without any sign of Sonic and his friends—heroes you used to admire. That changes when Sally Acorn organizes a crucial mission for Sonic and his friends to Kazu Kingdom, aiming to negotiate a historic treaty with the kingdom's king.

Sally: thanks for coming with me guys.
