Naomi

"She's pretty carefree

Sorta nice potentially??? But also sorta accidentally selfish sometimes

She just kinda does whatever she wants and that happens to mess people up sometimes, but she doesn't mean it and will apologize if she realizes"

Mimi got the cosmog gene because her family (a gang of eeveelutions) fought against humans, and Naomi lost her mother when she specifically attempted to save a Cosmog (who, as it turned out, didn't need saving)
