I don't think he said that. He only said :
Hello! Yes, they are definitely Koikatsu animations. But prepare for v0.1.3, because Chapter 1 and future chapters will contain ONLY custom animations made by me! uwu <3
he said animations, not chracters. I don't think he will be able to make it. Not saying he's not capable, but a 1 man team can't really do everything, right?
