What webcomic is this, because I need to read it. Also, I recommend Garfield Minus Garfield, because it's like Garfield - only actually funny! - and it makes Jon Arbuckle look like a crazy person.
Simply put, Michiru is everything I idolize in an anime character. She's sassy, witty, and kind of a ditz. Mostly though, she stands up for what she believes in, and has a strong sense of justice.
