[Demon Slayer] Isn't Rare Blood Just the Best?

[Demon Slayer × System]

[My take on a goofy, all-rounder, superpowered heroine with a system buff. Cheating her way to victory is no longer a dream!]

※ Pairing with Sanemi Shinazugawa; everyone else is family or friendship.

What’s the first thing a half-demon priestess does after getting a System?!

Youxing: Muzan, just get destroyed already.

The Kamihagari Family, in-laws to the Ubuyashiki Clan, have been priests for generations.

That is, until their family produced a half-demon, Kamihagari Youxing. The gods were furious and nearly punished the Kamihagari Family. Wouldn’t it be wonderful to team up with the Ubuyashiki Family and make a Demon Slayer-era married-couple package deal?

Youxing argued her case with the gods, painstakingly laying out the facts for three days and three nights. What kind of joke was this? The gods couldn’t chase performance targets like this! What would happen if the Ubuyashiki Family died out? How would they battle Muzan?

The gods were deeply moved. They smiled gently and said, “All right. I’ll show mercy and choose you as the scapegoat.”

And so Youxing began her journey of atoning through good deeds.

The more good deeds Youxing did, the stronger she became. Her best friend, the System, quietly let her in on the secret: the greatest good deed of all was sending Muzan to Avici Hell. Youxing was a clever girl from a young age, and she drew her own conclusion: doing good meant bringing warmth to the community by day and keeping the public safe by night!

For hundreds of years, Youxing stayed true to her original goal, kept her mission in mind, and devoted herself to serving the people, coming from the people and returning to the people. After mastering the five basic elemental arts of fire, water, wind, thunder, and earth, along with support skills like invisibility, teleportation, and telekinesis, she was having the time of her life.

[System: Time for an exclusive Demon Slayer news bulletin.]

[Shocking! Fourteen-year-old girl chases down and beats up a four-hundred-year-old demon! The reason behind it sends global sea levels soaring!]

[Is it a distortion of human nature or a collapse of morality? Mysterious woman razes a century-old religious site to the ground overnight!]

[You won’t believe this secret to poaching the scumbag boss’s underlings!]

[System: Demon Slayer news will continue after the break.]

As it turns out, whether you’re human or demon, if you act arrogant for a while, you’ll suffer for the rest of your life.

After an accident, Youxing lost all her spiritual power. Overnight, she was back to square one. Her Transformer instantly turned into a Volkswagen.

System: Times have changed, ma’am! The scumbag boss is sending his lackeys to beat you up!

Youxing: There’s no time to do good deeds and level up my skills! My dear System, save me QAQ!! I don’t want to die yet, aaah!!!

System: Relax. Extraordinary times call for extraordinary measures. Fight demons using the demon’s own methods! I’ll always support you!

Youxing: ???

System: Hurry up and drink this bowl of rare blood. One sip and you’ll power up instantly. Then let the music play and keep dancing!
