It all started with the question, "Have there been any local MS projects in the past?" I looked into it, but couldn't find any. I only found a sales page for local MS keychains, but instead of one mobile suit per prefecture, there were about three, and they were all the same type.
Among the three for my hometown of Kumamoto, there was a Gouf, so I chose the Gouf and decided to paint it in "red," which is Kumamoto's image color.
