Summary
A prophecy has arisen. Kamado Tanjirou, Agatsuma Zenitsu and Hashibira Inosuke aren't ready, but they have to be.
A coup the three unfurled.
A tempest to quell the world.In other words, this is a canon divergence AU of Greek demigods!Tanjirou, Zenitsu and Inosuke set in Demon Slayer, with some splashes of angst (because everybody suffers), fancy powers, too much sleeping on Zenitsu's part, and too much swearing on Inosuke's part.
