Quree built this 160 BPM piece on the famous Chopin "Ocean" étude (Op. 25 No. 12), rebuilding it as a driving electronic track. Its defining trait is being the first Schranz cut in Pump It Up history, a genre Quree acknowledged in his own posts. The BGA, created by LINUS and edited by RED-FOX, was shared on the composer's channel; many players compare it to the MILITARY SPLASH animation from beatmania IIDX 15 DJ TROOPERS. A Short Cut followed later, added in the June 27 update 1.03.0.

On PHOENIX the arcade set runs Single at S3, S6, S10, S15 and S21, plus Double at D8, D16 and D22. The S15 is a hidden chart unlocked by clearing the S10 with an S rank, a good place to drill short 16th trills; it rose from 14 to 15 between XX and PHOENIX. The S21 is a pure stamina chart with two waves of runs; the second adds complex siderun twists and was once judged harder than Imprinting S21, which is why it was bumped from 20 to 21. The D22 spreads that same idea across the full pad, with red-arrow twists that quietly drain stamina and a demanding Half-Double finish.

In the Short Cut the pairs S11/S18, S14/S21 and D14/D21 share a structure: the lower level appears in 8th notes, the upper one in 16ths. The S18 is nearly a full minute of unbroken 160 BPM runs; in XX it carried an EW speed-change gimmick that was removed in PHOENIX. The S21 opens with long staircases before sliding into Imprinting-style repeated runs. One notable footnote: the composer released his own D12 chart, which by his account nearly became official before being rejected, with SUNNY's design used instead.
