Not Prizmmy related but is related to Natsu XD
There is a show in Japan called "Idol x Warriors Miracle Tunes" where 3 girls (the 3 last girls in the slide/purple,pink,blue) fight and they are called 'Miracle2 (Miracle Miracle)'.
2 new girls part of Miracle Tunes become Miracle2's rivals. They were an Idol group in America called 'KariKari' who have moved back to Japan.
These 2 are sisters and Usukura Rina portrays the eldest sister Shiratori Akari and her little sister is Shiratori Hikari played by Nishiyama Mio.
KariKari have a song called Parrallel World which was included in Miracle2's single 'Catch Me'.
Think of it like Prizmmy.
Miracle Tunes is all 5 of them together (Prism Box)
The main group is Prizmmy which is equivalent to Miracle2 and KariKari is Prism Mates.
Just needed to update on them because Miracle Tunes is my current favorite XD
Besides I'm updating on Natsu's little sister XD
