Don't mind the pineapple lol

Can somebody help me with this mission?

I get what I have to do here (activate card skills 7 times when playing 1 song), but they activate only 5 times. Are there any tips or cards that have higher chance of activating their skills??? Here’s my cards in case I have such cards:

Here is a fancast of Love Live Superstar, an anime that I recently just got into, with characters from some of my favourite animes.

The cast includes:

Kanon Shibuya - Iroha Inukai (Wonderful Precure)

Keke Tang - Ran Hanamichi (Delicious Party Precure)

Chisato Arashi - Mashiro Nijigaoka (Hirogaru Sky Precure)

Sumire Heanna - Chiaki Ogaki (Yuru Camp)

Ren Hazuki - Nana Aokaze (Kimi to Idol Precure)

What do you think?

My theory is all of them born in Gen Beta which means Love Live extinct 30 or 40 years ago. Muse will become ancient while Aqours is in middle-age along with Niji. Liella & Hasu might be in early 20s

Rich girl i know is :

1. Maki

2. Mari

3. Shizuku

4. Shioriko

5. Mia

6. Lanzhu

7. Ren

8. Margarete

9. Kozue

Is there any rich girls out there than these? Maybe A-Rise Too?

And who is the most richer than the others? if you guys know?

I don't think u guys get enough credit for this wiki. Especially since new information comes out u guys add it or make a page of it a day or hours later who knows. I also think u need a thanks because the state Love live is in its really...sad to say the least. Pact with new stuff, but sad. So ty for sticking with it and doing what u do best :)
