I really don’t like her nickname ‘blackie’... I know the translator means well but i...

I mean Blackie is also a name used for a black haired dog or cat or any other animals. So that’s probably why he calls her Blackie

I might be wrong but wasn't that also the name of athanasia's Mana beast's
(who made me a princess?)

Nah it's just a common name for a dog in Korea. I suppose it sounds weird to people whose first language is English. Mine is not, and I literally had cats named blackie and brownie as a kid.

Yeah I also have a dog named Miss Blackie. Im Hispanic though but I don’t think that makes that much of a difference. I don’t think they mean it in a racist sense. More of a “pet” name/nickname.
