Reading the "Mission" reminds me of .hack//Legend of the Twilight, where this one character named "HOTARU" who was a US citizen in real life, but logged in to "The World" (R1) as her "final test" to test her Japanese-speaking skills. (Sad to day, her first experience was not as "happy" until a American player namded Sanjuro came into her aid.
I am not going to jump into the bandwagon since I am rust out on my basic Hiragana skills, plus I am not playing to play TO if I can't read anything. But since it's meant as a "visit" to experience and "test" your language like HOTARU, then I wish you the luck... Just hope you won't get caught and teased by the native players. ^^; (As I herd that jTO players are not as "welcoming" to the foreign players. Understandable.)
