A Doubleware (ダブルウェア) is a special kind of person capable of synchronizing with the data, and are compatible with Real Digitalization technology. This allows them to be inside of virtual spaces for an extended time without suffering the secondary effects of Outer Dependency Syndrome, a disease affecting humans who enter and exit a virtual space over long periods of time. Known examples include Tokyo Kuryuu, who was inside of The World R:X for the duration of the whole game as well as Lara Hoerwick who enters the game even more directly through The World's Epitaph Data. Side effects doubleware may experience include time distortion, and the ability to absorb data.
- Harald Hoerwick seems to have been the second human to fully enter the digital space, though it´s unknown if he did so in the flesh, as his consciousness seems to be trapped in The World after he tried to reason with Morganna.
- Tanaka Kakeru seems to have some sort of Double Ware-like ability, since his eyes glowed, showing the symbol. He has been under Tokyo´s monitoring for a long time due to this.
