I was thinking about that Oshitabi with Uika and Nyamu, and the former's inability to take a proper picture. That always surprised me a bit, considering how she's glued to that bloody phone. Furthermore, she's a 15yo zoomer, you would think taking good pics would be as natural as breathing to her.
I'm not sure if maybe I'm reading too much into this, and perhaps the joke was just that the seemingly perfect Uika, who can do anything, happens to be bad a taking pictures. But if I'm right, I really like that detail. It would show she's finally seeing some colour in her life.
I believe we usually take pics of things we like either to save those memories or to share our experiences with others. So, I was thinking that Hatsune is bad at taking pictures, because there was no memory she cared about saving or sharing, until very recently that something has changed inside her.
