Lul sunglasses and a gun. The sage is also really perverted and somewhat immature for living with and training 5 girls and being at the pinnacle of magic
I know it's manga logic but it's just really weird that after the miko was kidnapped and her elite guards defeated, they asked a pair of kids to find her.
@RedlineAlchemist on top of the in-character explanation that it was probably a public request to all guests, because even in setting asking young girls to do such a thing is acknowledged as odd, I think staff also saw them being familiar with third princess. Which would imply they were of some import either for position or power.
