This is the latest update.
They are half-sisters.
All six of Viscount Tasan's wives are official wives.
Two are human, two are beastkin, one is a Fawn, and one is an elf.
There is no Edda among them.
Note: Beastkin inheritance is basically random.
It's perfectly normal for a fox-type mother to have a rabbit-type daughter.
1st sister: 33 years old, unmarried. Next in line for head of household. Currently acting lord. Earnest and strict.
She has a tendency to rush people along. She admires Axe's swordsmanship.

7th sister: absurdly long golden hair that coils around her body. Black horns. A Fawn.
Stunningly beautiful. The kind of beauty that makes everyone turn and stare. Completely aware of none of it, and utterly uninterested.

Their father the marquis personally issued a decree forbidding it, saying she's far too dangerous.
