There are too many to list, but the one that comes off as being most awesome is where Red Turbo fights Yamimaru to a duel to the death.
Don't forget the fact that he also managed to kill the Big Bad of the series single-handedly, althought said Big Bad got better, though.
If there's any feat that's always mentioned in Haruna's portfolio, it would be her Fake Defector stint, suddenly acting like she's amnesiac and pulled a massive Face Heel Turn just to reveal an antidote she's looking for to cure a poisoned Youhei, all while pulling off a Biker Babe impression, hamming it up withEvil Laugh and complete with the costume. And it is awesome.
