This is the second part of the two-part prequel to Studio Trigger's (first) movie Promare, centering around the seemingly violent "burnish terrorists", and introducing their key figure, Lio Fotia.
You get about as much as you'd expect from a 10 minute character prequel - you get to know about the Burnish and their situation, after having been introduced to the firefighting "Burning Rescue" from the first short prequel.
Since this is only a prequel, I think there wasn't put as much effort into the art here as compared to the full movie - it's still your recognizable Studio Trigger animation though, with their contrastful color palettes and
quirky character designs.
If you've seen some other Trigger productions, you will notice a similar feel to this prequel. It was especially nice to hear some voice actors from Kill la Kill reappear, as well as some more teases of the great soundtrack from Hiroyuki Sawano, which are more prevalent in this second short, and which is fantastic in the main movie.
In case you've seen the first prequel about Galo, this short manages to showcase the Burnish's side of the story, and how the seemingly violent Burnish might not actually be as bad as the public thinks they are and that there may be more going on behind the scenes.
I watched the two prequel shorts after having seen the movie, and still enjoyed them as they gave me more info to what happened before the main events of the movie.
If you're planning to watch the movie, you might want to check out these two 10 minute shorts (the first one about Galo and this one right after), for some hype and to get you into the movie!
