See, that right there is where I think Yoko could learn to see why Kurama loves Botan in the future. She's a ride or die chick and would let him do what pleases him, wouldn't be a rabid fangirl, and would respect him for his title, strength, and how he effortlessly protects her from others. If there's a mission in Demon World and Kurama has to go Yoko to keep Botan safe, I'm sure the development would be great between the two. I even thought of Yoko testing Shuichi by trying to land a very convincing strike against Botan but Shuichi wrestles control and stops it dead in its tracks. It's not easy to assert yourself over him, and Shuichi did it so effortlessly for her safety. It's Yoko's way of understanding that even if he has most of the control, he can't abandon Botan for his own thrills, nor lay a hand against her. Love is a beautiful thing.

Hiei wouldn't be a dick to them. He just wouldn't know what to expect; Kurama is his own man and he chose Botan as his woman. It's something not entirely unexpected given the nature of their assignment and how much they must endure with simple-minded humans. I think he might even pass her a compliment and suggest that he couldn't have chosen a better lover for himself. Hiei for best man! And Koenma getting jealous? He should try to pop up in the middle of a hot-n-heavy session between them while they blow off steam but they're way too into each other to notice, or care. Funny enough I think Kurama is the type to be VERY AGGRESSIVE when it comes to personal time with her, uncharacteristically so. That Yoko in him running wild.

Aww Genkai for babysitter and all the uncles (Yusuke, Kuwabara, and Hiei) passing on some knowledge. Of course I agree that settling in on earth would likely be their ultimate fate, but their destinies are their own and Kurama wouldn't stop them from pursuing different walks of life. If they wish to be more than what the human world can give them, they're free to leave and pursue their own dreams. It's something Botan will need to come to terms with too as a mother. Their strength doesn't matter as much as their ambitions to me, and they would have two wonderful parents to help keep them on a good path.
