One interesting plotline could be the two of you navigating the challenges of living in the Hidden Leaf Village together.

And of course, there could be the comical moments of Naruto trying to do simple household chores in his own unique, clumsy way.

Well, it might be that Rias sees Naruto as a rival in terms of power or influence in a new setting. So, she uses her devilish powers to abuse Naruto.

Maybe he even teaches her about friendship and loyalty, which are concepts not as prominent in her world.
