The reveal that the big bad, the Emperor of Dornkirk, was actually Sir Isaac Newton, who had been isekaied to this world and used his knowledge to invent magitek and start the industrial revolution to build a mechanized empire that is taking over the world, and built a machine that can simulate reality and is trying to alter his own reality, was very interesting. It got me to sit up straight in my chair and really pay attention. I thought "oh shit it's getting great!". Unfortunately this reveal happened at around episode 20, when the studio ran out of budget. The show was supposed to be 36 episodes long, but they ran out of money and had to rush the last 16 episodes of plot in just 6 more episodes, which was disappointing.
