I'd love to help it meet your needs- RD is quite flexible, but it does require some tinkering and learning to use effectively. Of course if you'd rather just refund, you can contact itch.io support for that.
The program doesn't have any animation tools, but I'm wondering what you mean by a japanese style? If you mean something more like a 'chibi' style you can get this through prompts, without the need to use the modifier models.
