>>2172844My take on this is like that. She's disingenuous when she's bragging about becoming fluent in 5-6 months.
First, she studied in language school. She didn't learn japanese there, but she did learn some latin and spanish. More important, she learned HOW to learn languages there.
Second, it's not like she came to japan and went from 0 to fluent in half a year. Being a huge weeb she started learning jap way, way back. So she had the basics down, then she came to japan and only increased her proficiency from decent to native. That's something anyone can do with enough effort. And she definitely put in the effort.
Third, I think she just has a natural inclination to learning languages(good memory when it comes to words and images/patterns). She's a dummy in everything but that.
