Lu Bei, a computer science student, accidentally activates an old CRT monitor in a campus storage room, awakening an electronic life-form from another dimension called Gridman.
Injured while transmigrating across dimensions, Gridman's consciousness has fragmented. He can only reside within Lu Bei's understanding of code, and grants him the ability to transform into Gridman.
My version of Gridman's setting differs from the original, with just a few little changes.
