Thanks for the translation!
I'm extremely happy the father suddenly appearing didn't hamper Risa's playing. How it all happened was the best possible way. If I recall correctly, Risa wasn't even supposed to gain the father's blessing yet, only after the national competition. However, it's not like the dad wanted to torment her, so he instead took this opportunity to see, as soon as possible, if she's serious about music.
Since this is the end, unnatural as it might be, I guess we should be happy Shigure's fate could be considered to have changed. She's most definitely not alone anymore. The burden is now actually on the MC alone since he's the least talented of the three. I doubt Risa and Shigure would want to abandon him, like the first timeline band did, so the dude needs to train so hard he's sweating blood to make sure he's not holding those two back.
