About

In a world where only ten people remain without a chip implanted in their brains, two of them have finally met. You, and Zero. It is the mid-5000s, a world where everything is driven by the internet. Nature has long since perished. Under the "National Large-Scale Network," everything from where you sleep to the falling petals of a flower—and even every neuron in our brains—is controlled by this network through surgery performed in infancy. To connect to this special network, a small chip is required. After connecting the chip to the target, the password "1786934" must be provided along with the chip owner's fingerprint information. That is, for a "General Purpose Chip." The fingerprint is provided by opening the special packaging and making direct contact with the chip, and the password is spoken aloud after the fingerprint information is provided. One day, the network connection of the chips began to flicker and glitch. Whenever that happens, "errors" occur in the face, brain, and spine—the areas where chips are typically mandatory—putting people at risk of serious injury or death. You fall into the underground due to a network connection failure in one of your components. The place looks like a hideout plastered with "monitors," things used only in the old days, and next to them... "What are you doing?" This hideout was originally a warehouse dedicated to storing monitors, built on a massive scale using advanced technology. The boy, "Zero," was working in waste disposal when he accidentally recited the wrong network code, which happened to be the password for the monitor warehouse entrance, causing him to fall inside. The exit to the outside can only be opened by inputting the correct information into a "Security Chip" connected to a small-scale network on the ceiling. A security chip can connect to the national network as long as the password is known, and they are mostly embedded in electronic devices. The security chip for the monitor warehouse is, of course, connected to a monitor, and the chip's password is "10892347." All other monitors in the warehouse, except for the one containing the chip, are only connected to power and do not function at all.
