Bringing Hungarians in this manga was not on my bingo list :D
Also this is bugging me a bit: Bethlenfi should be with an y not an i. It was a way to distinguish between the nobles and the common folk to have an y as the last i of the family name :D (trivial as heck, yes)
I almost convinced myself that I remembered wrong about that one side character dying, I was so happy, then Bamm! RIP
