   Summary

   Sonic is just like any other Mobian in college, except being a little quicker on his feet. After his complicated relationship with his childhood friend and rival Shadow takes a turn for the worst, and fully realizing they can never be more than what they currently are, he faces heartbreak.

   Sonic then makes a desperate wish on a book his grandfather wrote in hopes that the future can be different, before finding himself pulled into the very lands of Camelot that it spoke of — facing the challenges of a foretold prophecy of a new kingship that he never wanted, battling against a darkness that wishes to destroy Camelot, and working with a mysterious knight who looks just like the one who broke his heart but swears his life to Sonic instead; a knight who makes him learn what love can truly be like.
