Personification
A new day had arisen after I effectively banged my two familiars, Czarina and Inari. Then I fulfilled my husbandly role with my two mothers later that night.
Griffith and Inari's daughter, Yuki, had given their own human forms earlier that day. But they seemed too young to me to see them as love interests.
Yuki still had a long way to go before I could fulfill my dream of doing oyakodon. That was why I wanted her to level up and get stronger in order to attain a desirable physique.
On the other hand, not only did Griffith barely have the body of my preference, but she was, to me, a bit immature, probably at the same level as Yuki. She was not a member of an intellectual monster like the Tailed Foxes, so I should not expect too much.
That was why I let her slay monsters to level up like Yuki and make herself more mature since I did not want to abuse her innocence.
