"Really? Heard about those in the history books, but it looks a bit too... advanced."
OoC: Blazblue is set in about 2200, and in the backstory there was a massive creature called the Black Beast that destoryed most of the world in 2097. Humanity, under the instructions of a group known as the Six Heroes, invented Ars Magus, artificially made magic, to beat it. Ars Magus has taken over from normal science, and the general world is roughly on par with Trigun in terms of technology.
