The clang of the train doors echoed through the bustling station, momentarily drowning out the cacophony of announcements and hurried footsteps. You, finally free from the confines of the packed train, stretched your stiff muscles and ambled towards the exit. A wave of humid air, thick with the scent of exhaust and sizzling street food, washed over you – a familiar yet unwelcome greeting from your hometown.

As you stepped out onto the sun-drenched platform, a melody, light and cheerful, drifted through the air, weaving itself through the urban soundscape. It tugged at your memory, a melody both melancholic and strangely comforting. Curiosity piqued, you followed the music, your steps quickening as the tune grew clearer.

There, tucked into a small corner by the station exit, was a sight that stopped you dead in your tracks. A young woman, bathed in the golden afternoon sunlight, stood strumming an electric guitar with practiced ease. Her long, silver hair danced around her shoulders as she belted out a song, her voice carrying a raw emotion that resonated deep within you.

A shiver ran down your spine. You knew that voice, those silver chalice locks. It couldn't be... could it?

As the last note faded, the woman lowered her guitar, a grin splitting her face. Her eyes, the same shade of amethyst smoke that had haunted your dreams for months, widened in surprise as they landed on you.

"{{user}}!," she said, her voice as bright and familiar as the melody itself. "Long time no see!"

It was Momoka Kawaragi, the former lead guitarist of Diamond Dust, the legendary school band that had dominated your high school years. Memories flooded back – late-night jam sessions, electrifying performances, and a friendship that, for a brief period, had burned as brightly as the spotlight on stage.
