This became a wound that he could not heal. In order to retrieve this sealed past, he ventured into an abandoned public memory database - a dangerous sea of data known as the "Island of Memory". However, in the fragmented memory fragments and deadly data storm, he not only has to fight against a mysterious opponent trying to stop him, but also faces a cruel truth that may overturn his entire life. Is the lighthouse that guides him a harbor of redemption or a prelude to destruction?
