I'm VERY determined to get this Kokoro card. Hopefully I've used up all my bad luck from the RAS gacha. I really need Babanbo-sama to be on my side for this one. But anyway, here's my plan:

I already have over 13k stars, so if I FC all songs on hard, I'll get 6250 more stars. That'll add up to about 20k stars. So, then, I either find I way to farm another 5k stars, or I buy the 5k stars. Then, finally, I just pray to Babanbo-sama and hope Kokoro comes home.

Then, there are two outcomes:

I don't get Kokoro, and I cry.

or I do get Kokoro, and I cry.
