Model Suit Gunpla is the Build Fighters before Build Fighters and Build Fighters Try existed. Instead of having a protagonist who is an amazing Gunpla builder or Fighter, the protagonist of the series is a beginner Gunpla builder named Haru. Unlike Build Fighters or Build Fighters Try, "Gunpla Battle" isn't a main part of the show and has more "teaching the viewer how to build and customise Gunpla at the basic level". Even though Model Suit Gunpla could be written off as a long advertisement, it didn't really feel like one when watching. I recommend you watch Model Suit Gunpla if you like Gunpla kits orare a fan of Build Fighters and Build Fighters Try.
