“Viscountess Chaplin, née the Hon. Gwladys Wilson” (1915) (detail) by Philip Alexius de László (1869-1937).
Did I just catch that you want to watch/play Hakuouki? Please do! It's a great series and a great game (I have the 3DS version). Every route is overflowing with feels and it's a very good introduction of the Bakumatsu era (1864-1869). I had watched Rurouni Kenshin prior to watching the anime, so it was really nice to see everything from the other side. I saw someone compare the characters to BM, but Kenshin would be a better comparison. And Chizuru is a great main character. :D
