Itchy Koo Ichinohei is the main female character in the Ben Dunn comic book Ninja High School.
She is the first character that you ever see in the entire series. She is a ninja, and she is going to be the leader of her clan, (but only with her grandfather approval). He wishes that she fulfill one request for him before she becomes leader. She has to marry Jeremy Feeple, (they had been promised to each other in childhood). Her plan is to marry him and then simply divorce him once she gains power. But after the first few issues she begins to fall in love with him.
Itchy is very similar to the character of Veronica Lodge from Archie Comics.
