Genre: Mystery

Still shaken by the information she received from the Men In Black, Lain discovers that she is being blamed for spreading an ugly rumor in the WIRED. Is what the MIB said is true; is she another person in the WIRED? Or is she doing it herself? Lain must find out or risk losing the one true friend she has.

As the Knights activities make the evening news, a strange man named Nazumi wanders the city with machines strapped to his body. People on the WIRED are asking: ""Who is Lain"". Meanwhile, the two MIB agents take Lain to the Techibana offices where Lain's identity is challenged by a man; how well does she know her parents, her sister, herself? Can Lain answer him?

Young children are acting strangely, arms outstretched and silently staring at the sky. A shocking vision suddenly appears in the skies; it looks like Lain! Determined to get to the bottom of this, Lain's investigations finally bring her to the creator of KIDS — but what she discovers is not what she hoped for.

Lain receives cryptic messages about existence, God, and a coming prophecy. Meanwhile, Mika's world changes in ways both surreal and hyperreal.
