Shirou
Really? thought Shirou as the girl explained the concept.
He'd expected that her use of "level" would be some kind of jargon borrowed from computer games the girl had played in the past, but it seemed like, somehow, the Pokemon he could buy would really "level up" through experience, just like an RPG character might. And, if it reached a certain level, it could change into a new and, presumably, more powerful form.
Before he could clarify things with her, though, her phone began to ring, and she turned to walk away. At the same time, he noticed a small dog-like creature on the floor where he had thrown the ball, just as the girl had said. There he saw a nervous-looking dog-like creature. As he approached it, holding his hand out to let it sniff, the dog began to bark. Shirou reflexively jumped for a minute, but did not back away, continuing to hold his hand out and let the dog sniff cautiously at it, before reaching out to stroke it.
