A massive influx of new sounds—112 base tracks ranging from J-pop hits to VTuber songs—had suddenly expanded the world. But it didn't stop there. 21 powerful data fragments, known as the DLCs, began raining down from the digital sky. Each fragment was a portal to a different universe: The Vocaloid fragment filled the air with synthetic voices.
The Touhou Project fragment twisted the tracks into bullet-hell patterns.
The Hololive fragment brought virtual idols to life alongside her.
Link realized that she was no longer just dancing; she was part of a "Wai Wai Party"—a massive celebration where the lines between music and reality blurred. As she rode the tracks, she wasn't just hitting notes; she was unlocking the memories of every player who had ever tapped a button or swung a Joy-Con.
The 21 DLCs weren't just "add-ons"—they were the building blocks of a never-ending concert. Link grabbed her glowing batons, took a deep breath, and dove into the next track. The world ahead was a kaleidoscope of color, and the only way to survive was to stay in the groove. If you’d like more, I can: Tell you about the specific songs in those 21 DLCs.
