From the anime Sky Girls, Karen Sonomiya is a shy, quiet girl with an IQ of 170. Basically she was the smartest one of the girls. She even graduated from university at the age of 16 yrs old! Her military rank is Master Sergeant and she is in control of mechanics. She is the pilot of one of the Sonic Diver's with her team of three. Her's is called the G2K1 Fujin.
Why I like her: She is totally cute. I really like her hair and smarts too. She worked hard to overcome any hardships with her partners.
Why I hate her: Too shy.
Overall: Karen honestly doesn't bring anything special to the show but it wouldn't have been the same without her either. Strike Witches is a better anime if you want some little girl military action.
