One of the things I noticed in this ep were the little personality quirks that were animated as well - for example, when Yaya ran up the stairs to ask to see Naru dance, or when Yaya put and kept her hands in her jacket's pockets while apologizing and kept them there, even while scratching the back of her head and pointing towards Hana while saying she did not accept her. I like little things like that.
I wonder how much of a main character the yakuza looking fella from the yosakoi shop will turn out to be. He even shows up in the OP, so I would assume he will be contributing somehow?
Interesting that Hana did always dream of being a ninja and trained in sports related thereto - freerunning. As others have said that is prolly as close to a "plausable excuse" for Hana being able to do what she does.
