Rider
Rider continued to sit and slowly eat her delicious food as Sakura and Ron talked business, nevertheless finding herself amused by Sakura theatrically summoning pen and paper out of thin air. However, when Ron mentioned a pet dog, her interest was piqued and, after Sakura had responded to his question, she spoke up.
"Oh, so, do you have a dog, then?" she asked. "What's it like?"
Shirou
Shirou could tell from her response that she was irritated by his question, even bringing up something called a "shiny" version, whatever the hell that was. However, before he could apologise for offending and upsetting her, she instead apologised to him, having realised that she had been assuming knowledge he did not have.
Instead, she explained the idea of a "shiny" Pokemon, and why it would be so expensive. Accepting her explanation and having no real interest in such a thing, he nodded.
"OK, a male would be fine, then. I don't think my wife will care either way", he said.
Then, having accepted that he was going to buy it and continuing to play with it as he spoke, he addressed some of his questions.
"How do you look after Pokemon, anyway? And how do you train them to be stronger? I'm sorry, but I know nothing about them at all, if I'm going to care for one, I need some help."
