After Turning into a Demon on the Same Day as Muzan

The Worldline says: You have to fight Muzan in a faction war!

Weakling Crow: Why not just let me die?

---If you become a young noblewoman in the Heian era and turn into a demon on the very same day as Muzan, what's your first move?

Weakling Crow: Go save the doctor, obviously. What are we waiting fo---

Weakling Crow: ...Oh.

Weakling Crow: Did I come at a bad time? (doge)

Weakling Crow: Run!

And so she vanished, hiding from Muzan for a full thousand years!

Weakling Crow: Muzan had a hard enough time hiding from Yoriichi. I'm even better at---

Weakling Crow: Wait.

Weakling Crow: Yoriichi?!

"I'm a small, helpless demon."

Usuba Karasu quietly writes the bold, eye-catching words on a piece of cardboard, then stores it in a slot in the System's inventory.

Once Yoriichi is born, she'll wear it everywhere she goes!

Weakling Crow: Please, your wife is my wife too. I'll protect your peaceful everyday life, just let me live!

Muzan becomes a demon, and the frail boy gets a cheat ability, the "Biological Card That Comes Infinitely Close to Perfection," and slaughters everything in his path!

Weakling Crow becomes a demon---

Don't believe fate is fair. If you do, it'll take advantage and play a joke on you that isn't funny.

Weakling Crow: Come on, look at Muzan! (pointing accusingly)

Weakling Crow: Why is my "weakling" label still here?

Weakling Crow: Do you even want us to win?

Weakling Crow: ...But luckily, it's a faction war. There are still plenty of ways to work the system, so...

Weakling Crow: I'll take that!

---Your Upper Moon is fine, and the next second it's mine!

Muzan: Who's eating away at my stats? (This isn't right!)

Usuba "Top Junkie" Karasu: I have no idea. (looks away)

Are you afraid of pain?

Can you do whatever it takes to survive?

Can you endure loneliness?

Can you bear the passing years?

Will you become a demon?
