Sis, Do I Have to Be Your Sword Scabbard Too?

[Absurdity] [Comedy] [Multiple Heroines] [Everyone’s a Lunatic]

Lin Yuan’s System has a bug.

[You have successfully tamed a space-time hound. You can turn it into the divine artifact Sky-Splitting Cloak at any time and teleport instantly.]

Lin Yuan stares at the border collie wagging its tail at him and falls into deep thought.

[Your unmatched wisdom has allowed you to pass the trial left behind by an ancient mighty being and learn the skill Time Stop.]

Lin Yuan looks at the advanced mathematics exam in his hands, the corner of his mouth twitching.

[You descended from the heavens in a furious frenzy, single-handedly subduing the world-ending witch Tang Feixue. You can transform her into a god-slaying weapon.]

Lin Yuan looks at the silver-haired girl Tang Feixue, who has tripped over her own feet and fallen flat on the ground in front of him. “Her? Tang Feixue? The world-ending witch?”

[Oh no, the System has malfunctioned.]

“Phew... I knew it...”

[The subjugation is not yet complete. To cleanse the witch’s corruption, you must call her Mom!]

“?”

My name is Tang Ling'er. I’m Tang Feixue’s younger sister, and I’ve been reborn.

In one month, a Lovecraftian apocalypse game will invade reality.

In my previous life, I gave it everything I had, but still met a horrible end.

Only as I lay dying did I learn that my sister, Tang Feixue, had become the sword of Lin Yuan, the top player, and was living like a princess.

Now that I’ve been reborn, I have to find Lin Yuan and sign a contract with him before my sister does.

He wields the power to turn all living beings into supernatural objects, making him the one and only king of this apocalypse.

Ah, my foolish sister, I’m sorry, but that’s just how the struggle for the heir’s place goes!

Huh? Wait a second!

How did I become Lord Lin Yuan’s scabbard?!
