Ignis

Ignis (イグニス, Igunisu) are programs with free will, and the creators of the Cyberse in the Yu-Gi-Oh! VRAINS anime. After various failed attempts to create life within the network, they were successfully created by someone who managed to create free will in a program.

Etymology
The creator of the Ignis named the lifeforms as such after the ancient mythology where God gave heaven's forbidden fire to humans, and which quickly allowed humans to evolve.
