"What a smart ruler you are! Most of them would either ignore these guys until they got to the planet, or send a bunch of incompetent buffoons after them."
Not even Delwyn is quite sure where Arianna comes from, though it doesn't appear to be Hinode or Hinoiri. She just showed up one day, years ago, dodged his guards and spells and, in between jokes and sarcasm, offered some damn good advice for the young ruler. Since then, her existence is officially a state secret -- given she isn't visibly aging, that's probably for the best.
Arianna is a very extroverted person, constantly saying what she thinks. Given her ability to handle complex thoughts over the long term, and understand motivations of adults, she doesn't always sound or act like a child, but she does take advantage of looking like a small child to be very touchy (both in the sense of hugging people and in the sense of not bothering to hide her emotions) and to indulge in things like reading comic books and getting away with everything. Her morality also seems to stem more from the practical than the ethical, though this could just indicate she doesn't see ethics as coming into her job. She also has a bunch of seemingly-irrational prejudices.
Unknown, but teleportation is one, and she probably has plenty more. She doesn't seem willing to exercise them on Delwyn's behalf.
AGE: Unknown, appears around 8
