Turned Into a Loli House Slave, Surrounded by Yandere Girls

My brother went missing for five years. When he came back, he was a blonde, twin-tailed little girl, a peerless archmage from another world.

She clutched the hem of her skirt, eyes brimming with tears. "Little sis, after becoming invincible, I transmigrated back..."

I raised a cleaver without hesitation. "Prove it! Make a mountain of gold appear!"

Our parents died searching for her. I work odd jobs, live in a rented room, and survive on instant noodles. I hate this "brother" of mine.

Now, this legally underage-looking big brother has become my only "get-rich-quick scheme."

But I soon realized things weren't so simple...

She's not only a max-level powerhouse from another world, but also a "little lamb" being hunted by all sorts of powerful women.

A yandere elf queen, a dragon princess with overwhelming possessiveness, a fanatical demon commander...

Their voices seemed to reach us from across worlds:

"We've found you, our 'adorable' Lord Green."

I looked at the ditzy "big sister" beside me, who could only turn things into gold and had the fighting ability of a total weakling.

Then I glanced at the strange fluctuations of magical power flickering outside the window.

It's over.

This isn't some bringer of wealth. She's a delivery straight to my door, box and all, weighing five jin!

Here's the situation now:

Me, a miserable working girl, have to protect my big brother, who's become a woman and has no idea she's a heartthrob adored by everyone.

And she, while trying her best to "print money" for me with magic, asks with a trembling voice:

"Sis, can I have sausage with my instant noodles tonight? The pursuers from the other world... seem to be here."
