Fuhito's father was Nakatomi no Kamatari, and his mother Kuramochi no Yoshiko-no-Iratsume. That's the official truth, anyway...

The emperor gave her to Gramps to reward his achievements or something, right?

Apparently it was a well-known rumor in the capital.

You're aware that Yoshiko-sama used to be a maid-in-waiting of Emperor Tenji?

Yeah.

Right. But the thing is...

They say, at the time that she married Kamatari-sama... She was already pregnant.
