Darkness belongs to Koki Terumoto, a late-series arrival whose fingers and feet weep a dark purple substance. Wherever it spreads, the ground stops being solid and anything it coats goes under. Nobody in his family had anything like it, and their answer was to shut him away.
Set down in Japanese as Yami, this long-range Emitter Quirk enters the manga in Chapter 429 and the anime in Episode 169. It stands apart from every ability in the Terumoto bloodline, an outlier of the same kind as Eri's Rewind, and that break from family precedent is precisely why Koki was locked up.
The output is a hazy, dark purple liquid that seeps from the fingertips and the soles of the feet. Turned loose, it washes over the surroundings and coats the terrain, and whatever it touches sinks down into it. How far the power actually goes, what it costs the user, and what else it might do all remain unestablished.
Presentation differs by medium. The manga draws the substance as a heavy fluid closer to ink or sludge, while the anime lets a wisp of purple smog rise first before the dark mass follows.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....

The Darkness quirk stood out as an outlier within the Terumoto family bloodline, unlike anything his relatives had. That break from family precedent is why Koki was shut away after his power first broke loose in childhood.
