“Papa, this dragon doesn’t taste good!”

“Papa, between you and the other Immortal-emperor mannies, who is more powerful?”

Xue An smiled. There was not a single soul that could withstand even just one blow from him. If there was! That would at most be two!

- Description from Novelupdates

On a certain day, a certain thought came to Japan’s Sun Goddess. ——Aren’t there too many Japanese people being abducted to other worlds? It’s true that the large majority of Japanese are diligent and docile and soft-hearted, which makes them pretty much the best people to ask for favors. “But recently it’s just gotten way too out of hand…… Oh, I’ve got it! Whenever a Japanese person is summoned, I just have to summon an otherworlder!” And now, every time a Japanese person is summoned, princesses and elves and beastmen and whatnot are reverse-summoned. Under the acknowledgement of the government, they begin living in Japan. Today, too, Japan is at peace. And so begins this laidback isekai cultural exchange story♪

Shi Man was the best special agent in the organization, and she was supposed to retire in peace, but they came after her to purge her anyway. She died exhausted after turning the tables against the organization’s agents… but was reborn, transmigrating into a book as its villainess! The villainess’s family is rich and powerful. Being the only daughter, her mother and brothers would pamper her out of control, and she was engaged to the male lead at birth. Yet, the body’s original owner messed up big-time despite being dealt the perfect hand. She harassed the female lead to win the male lead’s attention and affection until she eventually incensed the male lead. He threw her into the colosseum ring, where she was torn to pieces. Her family naturally went all out to avenge her and ended up suffering multiple casualties as they fell into desperate straits…

On the other hand, when Shi Man reincarnated, she told the male lead that they should go their separate ways and pretend they never knew each other even if they met again. She even paid the female lead with emotional duress compensation and told her they had nothing to do with each other from then on. However, after parting ways with them and preparing to begin a new life, the male lead regretted his choice and started wooing her. The supporting male characters who were never interested in her also had a sudden change of heart, and even the female lead was now offering to be her follower! Staring at the mob flocking around Shi Man, the Shi family was furious. “She belongs to our family! Stay away!”
