"BRING IT B****!!"
Attitude, jokes, nose-picking, "Kagura-rap," bluntness, beauty, strength, ideals...
She's got 'em all.
One of the most unique characters I have ever seen...and that's pretty hard to do in such a wacky anime. Otae's personality is nothing new, Kyuubei is cool but not something special, Sa-chan is definately different but again, nothing that's so different from the rest of the characters.
Kagura is such an integral part of Gintama; without her, it would lose its charm.
