I believe Master Uilos's question was more along the lines of are you using the Bendu version of Form I, TPLA version of Form I, Ludosport version of Form I, or some other version that I haven't mentioned?
Note that there isn't a "right" answer to this question, other than to help you with what members may know of the specific version that you're using. All of the forms are fictional, not even created for any of the movies, but afterwards. And their real life counterparts vary depending on the version, and even who's practicing it.
If you haven't already, I recommend reading this:

Sorry, I forgot to answer your question. After Form I, you go on to Form II. Now, I completely understand it feeling weird coming from a Kendo background, but look at it this way: learn it, not necessarily to use it, but to at least recognize it when your opponent uses it, and know how to counter it. Learning it will help you learn its strengths and weaknesses, and how to act in response.
