Every seiyuu popped up in both IDOLM@STER and Pretty Series

Last time, I made a quick list of seiyuus who popped up in both Love Live and Pretty Series. Just the big ones. I've done this in honor of both the Love Live and the Pretty Series' 15th anniversary. It's hard to imagine why both of these franchises poach each other's voice-overs for their idol girls. Long story short. Anyway, sticking to the 2025 idol year celebration, as THE IDOLM@STER series celebrated its 20th anniversary, it's time now for another quick list project.

Surprisingly, there's a long list of IDOLM@STER series seiyuus who got involved in Pretty Series projects since the Pretty Rhythm era. With the latest Pretty Series installment, Himitsu no AiPri, featuring IDOLM@STER seiyuus for the show's new characters, let's jot down the seiyuus who popped up in both IDOLM@STER and Pretty Series. Just the ones who can sing in both franchises.

That's how the Pretty Series managed to snag THE IDOLM@STER series' bests for such roles from Pretty Rhythm to the recent Himitsu no AiPri. You get the point.
