When Yin was wandering around, she generally stuck to her cat form. It was easier, she was less out of the way, and she drew even less attention. For whatever reason, a cluster of tails tended to draw the eye. It was also easier to feed herself when she was a small cat that could pounce on the stray mouse or bug that wandered near her.
Villages were nice though. People tended to be friendly to her. She'd get a random pet or a scrap tossed her way. Larger cities tended to see her and other cats as vermin, or at least something to be ignored.
She'd picked a spot near the outskirts of the village, along a knee high wall that had become overgrown with vine and moss, to eat the mouse she'd caught. Idly, she watched the comings and goings of the people in the village. Nothing particularly catching her attention until someone very much not villager-like made their way in.
Curiously snagged her and Ayami left the remains of the mouse where she'd been to trot after the interesting newcomer. He didn't seem to be garnering much attention, at least not initially, but she sat off to the side to watch. Bright gold eyes were rapt as he continued to declare his intentions, but it wasn't until he sprouted fire that she was delighted. It wasn't that Tuyet needed a wonder, or had a particular request, but she was excited and he seemed like fun.
What more could she ask for? Darting behind another low wall, momentarily out of sight, she turned into her human self. It happened quick, in the span of a blink. Where a cat had once been, a small girl with red hair, perky cat ears, and a cluster of tails was now on her hands and knees. Thankfully, she had enchanted clothes that shifted with her.
Tuyet stood up, brushed off her knees, and skipped toward the delightful wizard. When she moved, her tails entwined to appear as one, fluffy one behind her. When the wizard asked what he could do, there were a couple of villagers who shouted the obvious. "Make it rain" or "make it sunny for the next week!" Weather related, given their farming nature.
Yin, being of a different mind, asked instead, "Can you turn anything into a fish?" Then, to clarify, she held up a stick. As though that made sense. Stick into fish.
