As the Son of Muzan, How Am I Supposed to Get a Happy Ending?

On an utterly ordinary morning, just as the sunrise crested the horizon, a visitor arrived at Mount Sagiri.

"My name is Hayaomi Ochiri. Pardon my unexpected visit, Mr. Urokodaki Sakonji. I hope I'm not imposing."

Returning from his morning training, Kamado Tanjiro opened his eyes wide in the misty dawn and stared, transfixed, at the

boy who looked like the first snow of a new moon.

There is a widely circulated but never truly confirmed piece of information among the Demon Slayer Corps:

Above the Twelve Kizuki is a "Crescent Moon Envoy." His power is mediocre, but his status is second only to Kibutsuji Muzan. He also has the authority to directly command the Twelve Kizuki and deploy the entire demon race at will, keeping this vast species, driven by blood and brutality, running like clockwork.

If this information is true, then the "Crescent Moon Envoy," who single-handedly maintains the demons' hierarchy, would be the Demon Slayer Corps' primary target for elimination. His priority would be equal to that of the first demon, Kibutsuji Muzan.

Listening to this analysis, the newly recruited Demon Slayer Corps swordsman named Hayaomi Ochiri merely smiles faintly, saying nothing.

But a hint of ominous crimson glimmers in his crystalline pink eyes.

Content warning: The male lead is Kibutsuji Muzan's son, but Muzan and the other demons will not be redeemed. The male lead has a very contradictory character. He's neither traditionally good nor a conventional evil villain, and is probably about 60% good and 40% evil. Pairings: everyone has a one-sided crush on the male lead. Yuichiro survives. Hayaomi Kohaku, the male lead from Spirited Away, makes a guest appearance.

Theme: The push and pull of love and hate, the entanglement of good and evil
