Red Snow

Cashew, a composer from Indonesia, wrote "Red Snow" after being inspired by the Winter Theme from Harvest Moon (the Story of Seasons series); the intro in fact reuses that piece's main melody almost note for note. A 2011 version even exists, created while Cashew was still learning FL Studio and later recovered from a backup file. The song joined Pump It Up in 2015 PRIME via patch V1.15.0, and the XX update added an avatar called "Awakened Lyra" priced at 4,000 PP. In 2022 it was also ported to the game Chrono Circle.

Singles run from S7 up to S19, while the Double charts are the real draw. The D13 was a D12 from 2015 PRIME through Prime 2 and rose to D13 in XX; it opens gently but its tangled late twists are easy to drop judgment on. In Prime 1, unlocking the D21 (then D20) required an All Perfect on this chart, a steep condition that made many players give up. The D18, a FEFEMZ* UCS-contest chart added in Prime 2, plays well above its level and is widely treated as a D18 boss song, with a closing run worthy of a 19. The D21 leans on staircases, hold notes, and twist-laden runs that bleed stray misses. The D22 (XX 2.07), lowered to 22 in PHOENIX, stretches its runs over half patterns and double-steps.

The BGA was handled by ADZUKI and Lyrebird Ferdinant, the same team behind Nemesis, and was praised as one of the standout visuals among the PRIME newcomers. The animation's heroine is named Lyra (full name Lyra D Fersen); an old fan debate over her gender was settled once ADZUKI clarified the design. The piano heard in the track is FL Studio's default FL Keys, and Cashew personally authored the DP4 chart. The song grew into a trilogy: Red Snow Part. 2: Blue Moon (OverRapid, 2019) and Red Snow Part. 3: Black Flare (KALPA), plus an interlude piece and a piano-sheet version.
