There is only 1 thing he can possibly say now and live to tell the tale
"Your the girl that survived that monstrous queen's attack right? I challenge you to a dual!"
So why was that scene with dudes wanting to adopt her so fucking shady and at night? Was that a slave auction? Pedophiles?? Why did nobody end up taking her???
They probably just send her to free the saintess like she did in the real story
My best guess is that nina didnt have these healing powers in the real story and this is just the reincarnated girls power
