Zenless Zone Zero: A Former Civilization Professor's Life in the City

[Zenless Zone Zero] [Super Old-Timer from the Previous Era] [A Little Bit of a Troublemaker]

The first person to open a Hollow was stabbed by the student he trusted most. Trapped behind the Black Wall, he fought the progenitor Tartarus and took half of its authority in the process, before becoming embroiled in an endless struggle.

After years of trying every possible means, he finally reached a ceasefire agreement with Tartarus.

The price: he would never find a way out.

He stayed alone in the darkness until he went mad, then stumbled upon two siblings, both still young Proxy trainees.

"When you're able, take me outside, okay?"

Many years later, the Phaethon siblings once again encountered the benefactor who had saved them, now "scavenging" in the air.

From then on, New Eridu had an unemployed drifter who called himself the "Failed Professor."

An unparalleled genius, now so down on his luck he couldn't afford a meal.

But the student who stabbed him, and the progenitor whose authority he took by half, were both still out there.

The author pretty much writes whatever comes to mind, so please forgive anything that doesn't make sense.

The author's writing is also terrible. If you don't like it, drop the book right away and go read something better.
