Exactly, "good luck", very very good luck, with 25% it's tough and virtually impossible.Not really for BP. Even if you train every waking moment of your life and have the same upbringing/pure skill as Ruo. Good luck even achieving S if you have 25 BP
(Also yeah we can't swear)
If it was someone like Ruo, maybe he'd make it, it's lucky enough to be born where he was. That said, if he had been born with only 25% I think his grandfather would have thrown him into a ditch.
