Forgotten Vampire

The song was written by Korean composer WyvernP and debuted in Pump It Up XX after placing fifth in the 2018 Pump It Up content contest. It runs at 137 BPM. The BGA features illustration by ZM and graphic work by YSJ. SUNNY designed the Single and Double charts, while the Co-Op was handled by AEVILUX. In XX the top tiers (S18 and D20) were unlock charts purchased from the PP shop: the Single set cost 800PP and the Double set 1000PP, gated behind rank conditions such as S on S13 or A-or-better on S16, with matching requirements on the Double side.

In PHOENIX the Single spread runs from S3 to S18 and the Double from D5 to D20, plus a two-player Co-Op mode. The D17 is built around Half-Double and makes for excellent practice material. The D20 is the marquee chart: it carries a fairly long run section and spreads its twists evenly across the 1P, 2P and Half zones, which makes it genuinely tricky to read. Its peak is the close-angle twist run that kicks off after a 32nd-note allegro passage, capped by a "351CSZ"-style anti-MAX-combo finish that lands barely a second before the song ends.

On release the D20 was rated as a high-tier 20 for its twists and physical demands, but the low BPM drains far less stamina than expected and the run twists turned out simpler than they looked. By sacrificing a few notes in the closing stretch to lock onto the freeze notes cleanly, the perceived difficulty drops sharply, so it now sits in the lower-mid range for break-on play. For players chasing a full combo, however, it remains very tough. In version 03 the final freeze note of the weight-shift ending was worth a staggering 78 combo and climbed at nearly single-note combo speed, so missing it could force a game over even on the first stage. Version 1.04 reduced it to a 12-combo freeze note and ensured that, on a full gauge, this single note alone can no longer kill you; the tick rate of the preceding freeze notes was raised so that the total note count stayed at 1027 both before and after the patch.
