*points to the journal pic* ...................and she only gets one panel of screen time. :XD:
Seriously though, this is the first time we see her. Whether or not we'll learn anything more about her is never explained. For more information on her check out here: http://dragonball.wikia.com/wiki/Gine
That would be all. ;)
EDIT
Three panels actually as shown in the Dragon ball Wiki. :D
EDIT AGAIN
~UsefulYamcha (https://www.deviantart.com/usefulyamcha) provided a link to the TWO PAGES she appears in. :XD:
