Yeah he said, "here was talk of, "Wouldn't a sea otter be good for the Water starter?" But it was a really close decision in terms of what this sea otter would become once it evolves. In the end, we decided to have it evolve into something with a completely different appearance." A completely different appearance the starter evo's could be real people. Although, "Well, let's try blending a sea otter and a sea lion," I thought. I came up with the idea of making the shell on Mijumaru's stomach into a sword (katana) and using it to fight, and that's how I completed Mijumaru and its evolution." This might prove that they are fake who knows.
