There's a dark. A huge, unending, black mass of pure dark. It ravages and instills fear into the hearts of everyone it comes across, or whoever hears it's story of existence. People encounter it, go missing, and show up days later with no memory of ever meeting it. It's untrusted, it's dangerous. A hazard to the society where all is supposed to be peaceful. People pray to whatever gods in the sky that they never see it, never meet it, for they wish to never see it's eldritch wrath unleash upon them. Ojirou meets it. (Shinoji Two-shot)
