This represents my best effort to track down all the numbers possible. It should be noted that these are all Japanese numbers, as (reliable!) international figures are harder to come by.

• Credits
  • A huge portion of the data provided is from Media Create and, to a lesser extent, Famitsu. This info is mostly courtesy of Chris1964 of ResetEra.
  • Some first week data is from Gematsu (Media Create)
  • L&S first week data is from Dengeki
  • For the rest, it was straight from the horse’s mouth:
    • Ayesha
    • Escha & Logy
    • Shallie
    • Sophie
    • Lydie & Suelle
    • Nights of Azure
    • Nights of Azure 2
    • Blue Reflection

LTD (life to date) tends to mean that the game appeared in a Media Create Top 500/1000 list, so it really represents the last number I can find.

Grand totals are given at the end for convenience.

(The lower numbers notably have huge margins, but these are still interesting estimates.)
