My Junior Sister Can't Possibly Be the Demon Lord Who Ends the World

I raised my junior sister myself.

I fed her milk from a Zouyu, gathered snow from Kunlun Mountain to cook her porridge, and tossed snow lotus from the Tianshan Mountains into her cold dishes.

I even washed the diapers she wore as a child with my own hands.

When she was eighteen, she said she was going down the mountain to visit her family. But she never came back. I went down to look for her and found only a body with none of its seven souls and six spirits, just a wisp of her remaining soul.

I took her in again and began raising her while searching for her lost souls.

The journey was anything but peaceful. Countless people came looking for us, first with murderous fury, swords clashing against swords:

"You accomplice of the demonic fiend! Prepare to die!"

Then with polite words and heartfelt appeals:

"Immortal, you must not save her. She is a world-destroying demon. If she returns to the world, she will bring bloodshed and chaos."

I ignored them all.

I raised my junior sister myself.

I know better than anyone what kind of person she is.

She is a kind-hearted girl who can't even bear to step on an ant.

My senior sister raised me.

But I wasn't the only one she took in.

She also picked up a dragon, a sickly chicken, and a tiger with a patchy coat.

The more I see those creatures, the less I like them.

What's more, they mock her, saying she's just an ordinary mortal.

It's true that my senior sister is a true immortal, born of heaven and earth and gifted with divine powers. I can't do anything, and I'm always making trouble for her to clean up.

I didn't want to keep living like that, so I went down the mountain to study the arts and eventually succeeded.

I did hit a small snag along the way and became the world-destroying Demon Lord in everyone's eyes, but it wasn't a big deal.

Then I was ambushed and almost had my soul destroyed.

Luckily, my senior sister came to save me.
