[Demon Slayer: Obanai X Mitsuri] Winning Over My Late Husband Again

[Easy to read even if you haven't read the original work]

She was a ghost from the Edo period, dead and risen again.

Something called the System had brought her back to life. It told her she could choose a person to bind to and pursue romantically, earning various rewards.

But...

More than a hundred years had passed. That person no longer existed in this world.

So what use did she have for the System? She paid no attention to its suggestions, and gradually its voice faded from her mind.

Once, he had told her, "I'll grow stronger so I can protect you."

Now it was her turn to carry on his legacy...!

In the third year after her resurrection, she took part in the Demon Slayer Corps' selection exam.

Then, when she and her junior, Kamado Tanjiro, were sent to the Mugen Train, she met him again...

He said he was Upper Rank Three, Akaza.

To save Mr. Rengoku, who was on the verge of death, she hurriedly summoned the System, bound herself to "a certain character," and claimed the starter pack, which included a "healing potion."

But why is the affection level only 10?

Character: Upper Rank Three, Akaza. Affection level: 10.

Should she be glad that he'd truly forgotten her completely and only had 10 affection points left, or glad that he'd forgotten everything but still had 10 affection points for her?

"Ding. The target is thinking of the Host while reporting back to Kibutsuji Muzan. Affection has increased. Current affection: 15."

"Ding. The target is thinking of the Host while breaking Kamado Tanjiro's Nichirin Sword in the woods. Affection has increased. Current affection: 17."

"Ding. The target sees fireworks while passing through a human city. Affection has increased. Current affection: 45."

Huh, his affection can increase even when she does nothing?

Brother Hakuji, I suppose I can forgive your arrogance and rudeness when we reunited.

"Please note: This target has hidden affection for the Host. The Host may try to find a way to unlock it."

Koyuki: Just breathing.

Akaza: Affection increased...

A medium-to-long story about Koyuki resurrecting in the Taisho era. Koyuki has temporarily lost her memories from when she was a ghost. The System has a very minor presence.

In this story, Akaza has no clear memories of his life before becoming a demon until the Infinity Castle arc. The story focuses more on him, as Akaza, falling in love with Koyuki again. It's very steamy and features a demon lover, so please take note.

Here, "falling in love again" means that his affection was already at 100%, and now it's entered a second phase where it keeps stacking... Hakuji's 100% + Akaza's 100% = 200%. What a blazing love!

[Warnings]

[Please don't call the heroine a skin or an OC in the comments. Such comments will be deleted.]

[The male lead is nonhuman and doesn't have the morals or values of an ordinary person.]

[The male lead is stronger than the heroine and the story includes forced love and dark, obsessive elements.]

[The story is set in the Taisho era, roughly equivalent to the Republican era. The protagonists' past lives were in the Edo period, roughly equivalent to the Qing dynasty. A Qing-dynasty ghost lover won't have modern values of freedom, equality, and universal love, so please understand.]

[If you feel uncomfortable while reading, please stop. This is a free work, and I don't really want writing advice. Thank you.]
