[X] It's not just getting her away from her parents, it's being with you that's better for her. You know, you're the first person to have cared about her. You're important to her. She trusted you enough to defy you just now, and that doesn't come easily. She's a magical girl, with all that entails, and she needs someone who she can trust, someone who cares about her.
[X] Both of you deserve better than you've gotten from the world. I don't want either of you to have to scrabble for a life, Kyouko -- that's another reason why I'm paying you to train Sayaka. Heck, if I thought I could get you to agree to it, I'd set both of you up in an apartment like I have for some other magical girls who I met recently. There are ways to make it so Yuma could go back to school, too.
[X] And if it was just about "not being a shithead", I happen to know that Yuma's grandparents aren't the assholes her mother was. Maybe we could look into that. But if what you're looking for is a reason to cut her out of your life, then knowing what I know, I really don't think being separated from the first person she's ever been able to trust would be good for her.
[X] Talk with Kyouko while keeping an eye out.
[X] Deny Kyouko's self-condemnation. You believe she's a good person.
[X] Kyouko's become Yuma's role model.
-[X] You can't overstate how important, how good this is to Yuma.
-[X] It's not something anyone can be. Kyouko is special, and Yuma needs her.
[X] Ask Kyouko to see this as a chance. You trust her, you know she won't do wrong by Yuma.
[X] You don't want them to live on the streets either. There's options*.
[X] Finish the Hunt before talking further.
[X] *Options:
-[X] Let Kyouko know about Yuma's grandparents, and why she hasn't called them.
-[X] You can rent them a place. Even have someone 'hack' Yuma's way back into school.
