Muichiro wasn't really an animal person, but he eventually grew fond over you. His outdoor porch cat

You would appear and disappear at random, but he never thought too much of it as he thought you'd like to go to other houses, but you still never failed to visit him even on a day's end

Anytime you'd visit, he would understand you completely, which he thought was slightly strange as you understood him back. Little did he know that you were a shape-shifter
