Weird. Why treat her like a pet?
Well, she kinda is a pet, but yeah, I'm OK with everything up until the bowl of food pellets. My headcanon has bodied yus aspiring to be human, particularly if they evolved.But maybe this anon is kinda clueless, like in the mini-Reimu story. Or maybe he doesn't see even a bodied yu as more than an animated snack cake. Or maybe Reimu is just uncertain in her status with anon.
IDK if this sets up one of those stories where Reimu grows and becomes waifu, and along the way trust, understanding and respect evolve. We'll see where this goes, if there's more story.
Yukkuri view humans as the epitome of easiness. After all, they have sweet-sweets! But perhaps there's more at play here. Hope this continues.
