Yume is one of the Partners in Arcaea. She was obtainable during the Groove Coaster event in a World Mode map in Chapter 0. She was available for a limited time from January 9, 2019 to January 23, 2019.



Yume is unique in that she has voice lines. When online, Yume will voice her comments (in Japanese) for certain actions, as follows:

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

  • Their maximum FRAG stat translates to 1.04x fragment multiplier.
  • Their maximum STEP stat translates to 1.46x step multiplier for world mode.

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, 51 fragments are awarded, for a Pure Memory in Grievous Lady [FTR]:

$ (\text{CLEAR} + \text{PERFORMANCE} + \text{PARTNER}) \times \text{FRAG Stat} $

$ = (10 + 24 + 15) \times 1.04 = 50.96 \approx 51 $

Details of the calculation may be found in Fragments.
