[Blais, Brain Demon Gang? Didn't expect them to resurface.]
[Blais, But honestly, we had you marked as potentially from the Brain Demon Gang before; we can remove that now.]
The Brain Demon Gang was a modified gang similar to the Vortex Gang, but instead of favoring direct combat implants, they preferred skill chips.
Rather than saying they liked implants, it would be more accurate to say they preferred knowledge. In some old archives of Night City, the Brain Demon Gang was also a frequent source of cyberpsychosis, and their version of it was a special condition called "White Matter Madness."
Simply put, they knew too much, and their brains couldn't handle it.
Some high-ranking members were practically walking computers. Instead of using implants for direct combat, they preferred setting traps with their brains.
