Yeah... with how proactive Kosuzu is, especially with running her very own book rental, I actually forgot that Kosuzu is a literal kid – quite possibly about the same physical age as Akyū, and definitely younger than Reimu and Marisa.
🤔 Is Kosuzu already considered an adult by the village's standard? She doesn't go to school. In all likelihood, education like with Keine's terakoya probably doesn't go beyond primary/elementary.
Maybe, she does have friends from back when she's at school despite her interests, but they're all adults with responsibilities now, so they don't really hang out that much – and Kosuzu herself prefers to stick with her books anyway. Might be an interesting story. Akyū finding out about Kosuzu's own circle of villager friends.
