The Japanese title is called “Ryuu Tama” and it literally translates to “Dragon Ball”. We changed it to “Dragon Orb” so that you guys would be surprised to hear references to Dragon Ball >.>
In case you didn’t know, the whole chapter is based on the Chinese novel called “Journey to the West” which Dragon Ball was also more or less based on. For more info: http://en.wikipedia.org/wiki/Journey_to_the_West
Moe Ball – for those who didn’t watch DBZ. Son Goku has a move called “Genki Dama” or “Spirit Ball” which gathers “Ki” or “life force” and turns it into a ball. Miu’s version gets from various sources such as love, friendship, etc.
Gandhara – is apparently the name of the ED song of the live action “Saiyuki” or Journey to the West. For more info: http://en.wikipedia.org/wiki/Monkey_%28TV_series%29. Listen to the song here: http://www.youtube.com/watch?v=SDKH8R8I6_w
Tenjiku – is an old term referring to the country of India. “Indo” is now used to refer to India in Japan. That’s why Miu asked “What’s an ‘India’?” because she didn’t know “tenjiku” was used to refer to India in the old times.
