Cheng Mo's life fell into despair.

My younger sister is seriously ill and her studies are on the verge of collapse...

Until he picked up a mysterious compass, his life took an outrageous turn——

Save Nezuko, accept Tanjiro as his apprentice, and get involved in the dispute between the Demon Slayer Corps and Muzan...

"Wait, didn't you agree to just be a profiteer?"

"My Lord, let's discuss business. I'll sell you penicillin, and you'll teach me breathing techniques, how about that?"

"Ms. Tamayo, I have a report on modern genetics. Would you mind using some of my blood to study it?"

"Muzan? Oh, don't run away with that moving gift bag of time and space coins!"

Cheng Mo just wants to resell resources and make enough money to save his sister.

When he looked back, he discovered that he had already held the authority of countless worlds and became the largest behind-the-scenes supplier in the heavens!

Tanjiro: "Teacher, what is the 'currency' of this world?"

Cheng Mo: "It depends. Maybe it's a devil fruit, maybe it's chakra, maybe... the future of a world."

(No time travel, no system, multiple female protagonists.)

Ye Qiu was arranged by his mother with a bad taste to study in Neon.

Entered a girls' school called "Sakuragaoka".

Next door to the new house is a beautiful girl neighbor named "Su Shi".

On the first day of school, I met two strange classmates with weird personalities, one with extreme social anxiety and the other who liked stones.

By chance, he became a member of the Astronomy Department.

And because of his childhood sweetheart, Kotobuki Tsumugi.

He formed an indissoluble bond with several girls in the light music club.

By chance, I met a blue-haired girl on the roadside who had no money to eat.

After that, his wallet began to be depleted.

On the train to Kawasaki, I helped a 'rustic' girl from Kumamoto.

But he was scolded by the other party, "You are so arrogant!"

With these as starting points, he seemed to have formed an indissoluble bond with the band.

In the days that followed, I got to know more and more girls in bands.

It was so beautiful with everyone laughing and talking together.

Until one person broke the peace.

"I like you!"

Ye Qiu was shocked.

broken!

I've become a succubus!

The introduction is not enough, please move to the main text!

I, an ordinary person, inexplicably ended up in a place called Terra. But this time, I seemed to be born okay, and my family was quite well off. I had an older sister named Theresa and a cousin named Tracy. They cared deeply for me, giving me a house where I could enjoy myself and have fun. My dream of being a parasite had finally come true! (Happy.jpg) My older sister took care of my food and drink, and my cousin brought me video games from the East to keep me entertained. They even sent guards outside my door. From then on, I completely abandoned socializing, ignoring the commotion outside and never leaving the house! At most, I'd deal with the tutor my sister hired. Her name was Kal'tsit, and she was also a doctor, constantly trying to get me to study medicine! I refused! I was losing my mind to playing around! I'd go abroad and have fun! I'd leave the domestic affairs to my brother and sister! I was just planning how to get away when suddenly a large group of people rushed in. "The throne is vacant and the tribe is divided. Please inherit the throne!" "What does it have to do with me? I want to go abroad to study." Shining: "It seems that you didn't pass the exam." "......"
