"There's nothing more to say about this. She is a daughter of the Fujiwara Clan. Even if I won't let her enter the family register, she is still a Fujiwara. We've raised her for so many years; it's time for her to repay the family a little."
Fujiwara no Fuhito had never cared much for his daughter Fujiwara no Mokou. His other three daughters were all crucial to his climb upward, but... Fujiwara no Mokou's existence was simply superfluous, irritating to look at.
Fujiwara no Mokou's birth had been an accident. If not for the fact that she carried his blood, he would have thrown her away long ago.
His eldest daughter, Fujiwara no Miyako, was the Emperor's consort and had already borne him a child. That son had been named Crown Prince, heir to the next Emperor.
He, Fujiwara no Fuhito... was the Emperor's maternal grandfather.
His second daughter, Fujiwara no Nagako, had also become Prince Nagaya's consort. His third daughter, Fujiwara no Kōmyōshi, was betrothed to his grandson, the Crown Prince.
His fourth daughter, Fujiwara no Tabino, had yet to be engaged, but barring any surprises... she would likely marry into the imperial family as well.
As for Fujiwara no Mokou... that illegitimate daughter who had appeared by accident had no right to marry into a great noble house, much less the imperial family. At most, her purpose was to win over those provincial nobles who pledged themselves to him.
Though the returns would not be particularly great, something was better than nothing!
"Besides, marrying that provincial noble won't wrong her. At least she'll never have to worry about food or clothing for the rest of her life. As for you... you'll be leaving for your post in Heian-kyo in a few days. Make your preparations. Don't delay
