PersonalityEdit'Who's this little creature with swollen cheeks? She's stuffed too much in there!' - Yoon to Yona about Ao.
Ao is a goofy and mischievous yet adorable squirrel, often playing around and making poses that match the person she is riding on. She likes to eat a lot which makes her bite on random things, like Yona's earrings or Shin-Ah's finger. She tries to make people (specifically Shin-Ah or Yona) cheer up if they are feeling down or sad by rubbing their face or acting cute.
BackgroundEditAo met Shin-Ah before the events of the story. Shin-Ah was trying to cover a very soaked Ao from the rain with a large leaf. Ao just stared at him and then suddenly started to eat the leaf. Ever since then, she seems to have stayed with Shin-Ah, keeping him company even underground in the darkness, riding on his shoulder, proving that she is committed to being Shin-Ah's companion.
- Ao ranked 7th in the character popularity poll conducted by Hana to Yume in December, 2014. She scored 550 votes in total.
- Ao has a habit of stuffing an acorn in the mouth of those who are sick or injured.
