I personally wish that this either became a full length film or a new series because the concept is very interesting. As it is though, it's well done. In just around four minutes, the concept movie is able to get its themes and points across clearly. It calls back to what happened in Rebellion as well as contain a lot of symbolism and hype. It's definitely a good opener to SHAFT's future projects during that time. The animation and artwork are just as great, perhaps more focused since it only needs to be four minutes. The voice performances are fantastic and the OST still hits. If youhave the chance, you should see this concept film yourself. It's only four minutes and it'll be worth it.
