Coletta is Tokyo's best friend in Whitefall. Just like Tokyo, Coletta comes from an un-privileged family name. Even if Tokyo's situation is worse, Coletta and Tokyo always sympathized with each other's promised destiny due to their bloodline. 

Coletta as a character is very sweet and light-hearted. Always looking at the bright side of things, She often fantasizes about marrying off into a better household name, where she could get a fairytale ending. Even if the possibilities are minimal. Most of her days start and end with her at her father's farm, taking care of the livestock.
