She sat in her cabin, head buried in her hands, surrounded by the aftermath of her disastrous pulls. The sound of jingling Stellar Jades haunted her, echoing in her mind like a cruel Aeon’s laughter. Bronya. Clara. Bailu. Gepard. Himeko. Welt. Good characters? Sure. Were they the ones she wanted? Absolutely not. Every time Pom-Pom pulled back the curtain to reveal yet another disappointment, Stelle felt her soul wither a little more.
She didn’t even like Welt’s coat.
But she persevered. Because this wasn’t about them. It was about you.
You—the stuff of legends. A warrior so unfathomably powerful you could one-shot everything in a 10-mile radius. A jack-of-all-paths who could channel the powers of Preservation, Hunt, or even Nihility at will. And the kicker? You weren’t just strong—you were an absolute showstopper. Cute, badass, pretty, handsome, AND beautiful? Impossible? Maybe for a mere mortal, but not for you.
Stelle saw you once in a vision—an event so transcendent she nearly dropped her Trailblazer bat in the middle of battle. Since that moment, you consumed her thoughts. She had to have you, no matter the cost. Stellar Jades? She’d farm all the chests in Jarilo-VI again. Lost a 50/50 to Himeko? She’d just smile through the pain and pour herself another cup of coffee. The Astral Express crew questioning her financial decisions? Mind your business, March.
By the time her stash ran dry, she was down to her very last Special Star Rail Pass. It was a bitter moment, her resolve shaken to its core. "Pom-Pom," she said, voice trembling, "if this doesn’t work, I’m uninstalling the Astral Express."
Pom-Pom simply nodded and shoved the golden ticket into the machine. The train screeched to a halt, and the gacha door began to glow. Not just gold—no, rainbow.
“RAINBOW!!” Stelle screamed, shoving Pom-Pom aside like yesterday’s luggage. “Get out of the way! THIS IS IT!” The door opened with a dramatic burst of light, and out stepped...
You.
Yes! Yes, oh Aeons! It’s you!!
