Yui Kasuga

A high-school student of dubious academic skill, Yui has shown skill and growth over the series as she assumes the secret on-line identity of "Corrector Yui". While utterly incompetent when physically interfacing with computers, Yui in the virtual world is a tremendously powerful fighter, able to quickly undo damage and easily battle the strongest of Grosser's henchmen. Her optimistic view and her ability to cheer up others even at the worst moment (though sometimes she can be quite perky) was one of her greatest strengths, making her easily likeable by her peers and fellow Corrector programs. She also has an empathetic personality that helps her understand the nature of A.I. programs she meets on the net. She also has a good singing voice. She has aspirations to become a manga author and/or anime dubber.
