- 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, 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.
