A year has nearly passed and the 8th world championship is approaching. Brother and sister Graeme and Serena are entering, and on the way though they make new friends who are new entries along with encountering some familiar faces.

Ever since the battle of the 7th GBWC, many things have changed. The only thing that hasn't changed is the passion for one thing: Gunpla. Now this story will give rise to a new Fighter, whose dream is to become the best. Not the best description, but a good story I believe. Read and Review and, if you want, Favorite. Thanks :)

Original Character story This is the story of a Boy named Theo Stewart who dreams not of battling gunpla, but simply making them fly.

Moving to Japan is a young Gundam fan's dream, especially for an avid Gunpla Fighter like Leo Allcraft. However, the path to becoming a Top Gunpla Fighter might be easier to see in the Land of the Rising Sun, but Leo is about to find out that it is also a hell of a lot harder.
