Midou Mayako

Daughter of Ross Midou, the Kingdom of Eldia's Ambassador. Marina was hired to protect her from terrorist attacks.
Because of her dad's constant travels between Eldia and Japan, she has almost no time to make friends, and is quite reserved as a result.

Spoiler

Actually a genetic clone of Purin/Prisia and only about a year old. She was created to serve as a vessel for the King of Eldia's consciousness.
