Bio: Ruri is a crew member of the Nadesico. She is intelligent and likes to say "Baka" or as it is translated "Fool" a lot. I'm going by the ADV subs here. She is around 11 years old. There's more to her, but my memory is off and some things are spoilers.
Opinion: I like her because she's cute and very smart. Her catch phrase of "Baka" doesn't get as annoying as some catch phrases. Simply because she says it quickly and gets it over with. Also her backstory doesn't dominate her character that much. Finally she is a bit negative in some ways. The decent type negative. Which is.... Okay so I have do way of describing it.
