Xiang Zhiren, from Machang and Renjia, is a junior high school student in Yinghuashan Junior High School. On weekdays, a secret laboratory is set up under Pingjia, whose parents run interior decoration shops. And with the computer "garbage" made of medieval parts as the center, research and development is carried out day and night.

That classmate is also straight, but because of his insidious personality and no friends, he became a computer enthusiast. While indulging in the monster creation game "Castle of Torture", Fujitani met the virus demon king Kahn Digifer who escaped from the "computer world" of another dimension. He used his negative emotions to create various monsters for him and sent them to various computer cyberspace to wreak havoc and dominate the earth.

Just as three straight people realized the abnormality of "computer world", CG. Yiping's electro-optic superman gullit/Gridman made in Garbage turned out to be a warrior from the "computer world" who incarnated in pursuit of Kahn Digifer. Straight people joined him to fight against gullit, became the soul of gullit, and launched a battle with the evil virus monster.

In this way, the war between Xiang Zhiren and Wu Shi, and between Gu Li and Kahn Digifer is about to start.
