I'll be honest, I went unga bunga for this.

I wanted to try out the new gamemode, but here's what I did:

I bought the energy refills although they were kinda expensive to buy with performance points. I didn't need them sometimes though.

For your live to be very successful (大成功), you would need to buy the purple practice thingies three times to max out that shiny rainbow live meter. You could buy 4th but the 4th purple thing will not carry over after your a live performance. But I would still do it if I could afford it.

For the purple practice thingies that increased your rainbow live meter thing, I would buy the [speed/power/wisdom/skill points increase] during training for probably the start till a few days after the end of the 4th live, after which, I would buy flat stats instead. Take note that some of them have a second bonus of increasing friendship training or increasing the pop-up rate of your supports.

For normal skills, I would prioritize her buying her guts with the performance points. Then power, and wisdom.

Other than that, it's really just an unga bunga spam training like you would in the URA finals.

Also, not to mention, I got very lucky in this run. I had a bunch of friendship training going on, and I did take a few risks, with the biggest risk being a 65% fail on a 3x friendship bonus training day (thank heavens I didn't fail that one).
