He also realized something important recently.
If he gained Catherine's bloodline and Physique, he could be intimate with her regardless of rank.
That understanding came from the Sword Empress' words.
Celestial Kitsune were a species that had intercourse with anyone, including neighbors, parents, and even their own children.
Catherine herself wasn't like that. She had strong self-control. But the species as a whole had a reputation because their rank differences didn't matter within their race.
If it did, they couldn't have coitus with their children and parents. There was no way all of them were of same rank.
Which was partly why they ended up with so much incest. They had trouble finding compatible partners among other races. So they turned inward. That interbreeding caused genetic disorders, and those disorders destroyed their species.
Isaac exhaled and pushed those thoughts away.
He had more important things to focus on.
'System, share her affinities!'
