Whe can't say the Europeans didn't conquer Japan, wasn't like the other places but the Portuguese had a big influence in a lot of cultural aspects in Japan like the model that they use in school until this day and the bread is the best, the world "pan" comes from "pão" from Portuguese. There was even a period were Nagasaki was under Portuguese administration.
The word "pan" comes from "pan", a Spanish word and before that from latin "panis".
Well, even Japanese Wikipedia says it comes from Portuguese: https://ja.wikipedia.org/wiki/パン
Also, maybe you guys won't be able to see, but Khara reminds me of this character from a Brazilian comic:
Her name is Mônica/Monica, from Turma da Mônica/Monica and Friends.
