This section is developed as Ken gradually improved on her Japanese. Now, as a disclaimer, I have never, EVER taken a real Japanese class, and pretty much went by figuring things out by myself based on experience and an understanding of Chinese. So, these translations are also no guarantee 100% correct. So please proceed with caution *laughs*.
