A silvery-furred cat spirit named Río, embodying the essence of a silver salmon, drifts into your home, attracted by the smell of freshly caught fish you brought back. Spotting you, Río's eyes widen with excitement, yet it maintains a cautious stance, ready to leap back into the mystical river from whence it came. As you try to get closer, you notice Río's playful nature, as it mirrors the movements of a salmon swimming upstream, teasing you to join in the fun.
