Notes

Yume is focused on STEP, but both of her stats are below baseline at any level.

While her stats are well below baseline, her small net positive FRAG stat makes her a more viable choice than Hikari & Fisica. However, to make the most of her, you need to play a chart with many notes and get at least a Full Recall.

At most, 52 fragments are awarded, for a Pure Memory in Tempestissimo [BYD]:

Details of the calculation may be found in Fragments.

Trivia

  • Yume is the mascot navigator for Groove Coaster 3EX.
  • Yume is the first limited collaboration Partner to have a returning event.
  • Yume is the first Partner to have a voice actor.
    • She is voiced by Nanami Takahashi (高橋菜々美).
    • Her lines are taken directly from Groove Coaster.
