Corrector Yui

Yui Kasuga struggles with computers in a world increasingly dependent on a vast network. When a program named IR draws her into that digital realm, she is asked to help stop a rogue system from taking control.

Working with the Corrector programs, Yui learns to use special abilities to repair damage and protect the people affected by it. She brings courage and empathy rather than technical expertise to a struggle whose consequences reach well beyond the screen.
