Mairin is a clumsy girl with a very forceful attitude, often tripping over her own feet and believing Alain to be her boyfriend contrary to many objections (Alain included). She may appear to be a child, but she is actually a eighteen-year-old woman who suffers from Loli Syndrome. There is no known cure to this condition, and she often gets flustered whenever it's brought up.

I reccomend a somewhat mature voice to hint at her true age.
