アリア・アリアリア

An elf who lives in the forest with Nico and is the Flat Chest Tribe’s Maiden. 

To the untrained eye, without a good grasp of Elf life spans and aging, she appears to be quite young; but she’s easily over a thousand years old. 

Normally she acts hyper and girly, but she gets mad when her age is mentioned. Despite her age, she has a rather mischievous personality. 

She dotes on Nico as if she were her grandchild, but she doesn’t like being called ’Grandma.’ She keeps trying to get people to call her Aria-chan, but it doesn’t seem to be working.
