You will need to understand that Poser is not a modeling program, you would do better creating something in Blender.  But, it sounds to me that your intention is to use an existing figure and export it to another 3rd party software as part of a workflow pipeline for animation.  It would be worth the price if you expect to use Poser on a regular basis but considering that you intend to export an Anime-based character based on a model might diminish your expectations.  Download the trial version and experiment with it to see if it will do what you would like it to do.  It's not worth investing in the software and bundle just to find out that the pipeline won't work.  And besides, there are models available on other sites that can be imported, rigged, and morphed in Blender for perhaps a fraction of the price.
