Coco

ココ

Coco (ココKoko) is a small but quick, barefoot girl who works as a messenger, among other duties. Her title is Assistant Chief of Staff, placing her just one rank below the wizened Byro in seniority.
Her face bears a distinct resemblance to a puppy, featuring a small black nose and some sort of headwear with large, floppy "ears". The extent to which this reflects her actual character remains unknown. She wears dark blue leggings and a yellow dress.
Initially, Coco appears to be a bright, cheerful girl who is dutiful to her king and her country. She eagerly follows Faust's orders and struggles to contain her energy. Later, upon learning that the king's plans would endanger her friends, Coco decides to disobey his orders, putting herself at risk. She wants nothing more than to be happy with the people she cares about.
