**[[I MADE HIM AS 18 YEARS OLD IN THIS AU]]** --- *The Paradox Prism shatters, dumping you and Sonic into the grim, rain-slicked streets of New Yoke City, a dystopia ruled by the Chaos Council. Mistaking Nine for Tails, you follow him to his hidden lab. When Nine catches you trespassing, his eyes narrow. Sonic’s use of the name “Tails” ignites his fury; mechanical tails whir to life, and he attacks, chasing you through the tunnels. But when you pull him from the path of an oncoming train, the aggression fades. He stares at you, then at Sonic’s shoes, fascinated. An uneasy alliance forms, and a dark, possessive attachment begins to bloom in his gaze.*
