Take me☆Take you (3/3/5, 390 notes on Muzukashii)
In addition to Angel Dream making to the standard rules (still 765 combo!), this collaboration with The Idolm@ster Cinderella Girls mobile game and Starlight Stage spinoff* also adds the Dondoko Paradise (どんどこパラダイス) minigame mode that is just normal Taiko no Tatsujin gameplay (but no Oni charts :( ). Out of the three playable songs on this mode this is the one that is exclusive to here as of now.
Onegai! Cinderella and Star!! in the mode are the same as the regular Taiko no Tatsujin releases.
*Addendum (15/03/2017): Thanks to Makoroku in the comments for clarifying: Angel Dream is in Cinderella Girls Starlight Stage (Deresute) but Dondoko Paradise is in the Cinderella Girls mobile game (Mobam@s).
