Miss Wuchan's Online Survival

Only when her life ended did Ubuyashiki Tsukihime remember her past life and realize that she was none other than that utterly pathetic, lowest-of-the-low creature who spent every day loving herself: Kibutsuji Muzan, gender-swapped!

Terrified, she immediately did sit-ups, tracked down the quack doctor she'd driven away, and drank a bowl of medicine without a word, successfully transforming into the ultimate life-form.

She had immortality. Now the question before Muzan was how to squander her endless lifespan.

Anyway, looking at an era with no entertainment whatsoever, she set herself a modest goal: survive until modern times, at least, so she could play with a phone. Don't provoke the protagonists. Just be a cautious survivalist.

But could someone explain why the Demon Slayer Corps had still been formed, even though she hadn't turned many people into demons? Will they never stop?!

She'd like to see who was using her name, Muzan, to cause trouble.

Any demon using her name: slap them first, then kill them.

Any scumbag who dares provoke her: slap them first, then kill them.

Any demon who doesn't obey: slap them first, then kill them.

In short, Muzan's main principle was never to let herself be even a little displeased.

Could someone explain why those people from the original story who opposed her, that certain son of God, Sukuna from the neighboring series, and the Six Eyes, were all following her around like stubborn ghosts? What is wrong with them? Kill them all.

Content warnings: Gender-swapped Muzan, everyone falls for her, otome romance

Multiple endings

[A ridiculous story. Who doesn't love the gorgeous, wicked woman Muzan? Harem otome romance. Muzan doesn't drink ordinary people's blood, only the Upper Moons'. Only the strong deserve to have their blood sucked by Muzan. No weaklings.]

Theme: Maybe it's still better to be a good person
