I don't see her earning anything over B Rank, at least not for a while. Maybe when she's older she can go train with Genkai in the Spirit World. Imagine if a demon or some kid at school messed with them? She'd probably break their wrist but then remember that's not polite and then later, Yoko would haunt them. XD Though Botan would feel pretty privileged to know he puts her on the same level as his mother. Suck it haters.

I see her as the cuddly drunk who likes to dance but if someone does press her for info, you bet she's gonna blab so if Kurama doesn't want everyone knowing he's a scary demon, he better find a way to shut her up or hide her away~

That would be super sad. But Koenma can't keep giving Botan special treatment if he's already letting her live in human world while still being a grim reaper. She's gonna have to make some excuses while she ferries people away, at least before she and Kurama come clean about themselves. But imagining heartbreaking ideas of Shiori dying and not being able to help Botan through the delivery is too sad to think about. We're on page one, man. XD We need happy happy~
