This story needs to start focussing on what Koyuki can do and less on what she can't.
Sigh. And we have a dark-haired girl is afraid of heights trope. Aw geez, please end this trope-horror. She couldn't even buy the plushies? Really? Aw yes! Thank God! She did buy them after all.
And Koyuki looks like she's got it figured out now. I hope. She looks happy and determined. Hopefully, she'll be bolder now.
