The Tyrannical Sukuna and the Charming Muzan

Blurb:

Yue Yan is a young nobleman in Heian-kyo.

Frail and sickly since childhood, he has been told by every doctor his family has summoned that he won't live long.

He refuses to accept it. All he wants is to stay alive! He knows he can do it!

Then one day, a sorcerer as powerful as a demon god attacked Heian-kyo.

The man was given the title "Ryomen Sukuna." The nobles, who feared death above all else, avoided him at any cost, but for some reason, he took an interest in Yue Yan.

Yue Yan has the usual arrogant, selfish faults of the nobility. Of course he doesn't want to yield to someone he considers beneath him, even if that person is a powerful sorcerer.

--But Sukuna has the Reverse Cursed Technique.

A Reverse Cursed Technique that can restore Yue Yan to health and let him live to a ripe old age.

"Lord Sukuna..." Yue Yan leaned tenderly against the demon god. "All this blood is so frightening. Won't you spare them?"

As long as it keeps him alive, he doesn't mind pretending to be the "weak and kind" young lord Yue Yan that Sukuna adores.

[Reading Notes]

1. Sukuna thinks Muzan is kind, so he restrains his urge to kill. Muzan thinks Sukuna likes that sort of kindness, so he keeps up the act. Two wicked people cancel each other out, and the world finds peace.

2. Muzan dies of old age. He will not become the Demon King.

3. This is a short story. Depending on how things go, I may add other Jujutsu Kaisen ideas that I don't plan to develop into long stories. Sukuna and Muzan are just one of them.

Coming soon: Replacing Muzan and Ending Up in the Wrong World [Western Crossover]

Blurb:

Because of a deal with Izanami, a monster from the abyss spent ten thousand years holed up in hell.

At last, after tricking a dim-witted Demon Progenitor, it successfully stole his identity and escaped.

But--

Why is it daytime in the human world now?!

Under the blazing sun, Muzan sprinted through an endless desert, smoke pouring off him, utterly frantic.

In the middle of his desperate dash, he caught sight of a dark, shapeless object from the corner of his eye.

Muzan slammed on the brakes.

--Look what he'd found!

A wild cape!

A cape! One that blocks the sunlight (emphasis added)!

Muzan was ecstatic. He quickly stripped it off and draped it over himself with a satisfied grin.

Finally safe beneath the blazing sun, Muzan breathed a sigh of relief.

--Thanks, Mother Nature (?)!

What? You say there's a person under the cape, too?

That doesn't matter ╮(╯▽╰)╭

An injured, unconscious bat: "..."

P.S. Also known as The Years I Spent Happily Ever After with a Bat-Cape (?)

[Reading Notes]

1. An outrageously crack ship: Batman x Muzan. The blurb makes it clear this isn't the original Muzan, and he'll be a lot more human.

2. In a way, this should be a comedy.

3. Muzan's powers will be boosted somewhat. He won't instantly die in sunlight.

4. The protagonist doesn't know the superhero world's plot.
