~EDIT: In the list
Well really it's not new since it came out in 2006, but obviously it's new to me... Anyways, it's called Le Chevalier D'Eon. Although the title and titles of each episode are in French, the people speak English. It's basically about this guy and his friends who are trying to figure out why his sister was murdered. The creepy thing is, it's waaay similar to Black Butler.
1) Set in Europe (England, France)
2) Work for royalty (Queen Victoria, King Louis)
3) Seeking justice for murderes of family (parents, sister)
4) Otherworldly encounters (demons, magic)
5) Dress up as girls (Robin, sister)
6) *I would say both young males, but Ciel is 12-13, and D'Eon is 17-19.*
7) Engaged to Mary Sues (Elizabeth, Anna) Anna isn't as bad though.
It's pretty weird how similar they are... But I'm on episode 5, and I'm loving it. I can't wait to watch more.
