Multiple female characters, plot-driven, fast-paced, scheming, ruthless, and unscrupulous.

Kano was transported to the world of One Piece and unfortunately became a slave of the Celestial Dragons.

Fortunately, he ate a Devil Fruit and gained the ability to become stronger by making contracts with others.

And so, Kano made a contract with the Celestial Dragon Serendel, completing a life-changing turnaround.

Unfortunately, the housekeeper was very familiar with Celine Dyer, and soon his secret was revealed, so he had no choice but to make another contract with her.

With the help of Celestial Dragon Serendel, Kano grew rapidly and, under the pretext of this, summoned Ain and Tina, both Marines, to be his sparring partners.

Knowing the plot and their personalities well, Kano quickly formed a contract with the two. Later, CP0 Stussy and Gion Momousagi also fell into his hands.

So, now it's time to set our sights on the ocean. Nami, Robin, Boa Hancock, Uta—it's time to change the course of their lives.

Hirakawa Seisui, a transmigrator reborn into Konoha. In the ninja world, where bloodlines reign supreme, he was merely a commoner ninja, destined to be cannon fodder on the battlefield. However, fate intervened; he activated the Medical Ninja System. Good news: the system boosted his medical ninjutsu talent to the highest level, making him a Primordial Healing Body. Bad news: it only enhanced his medical ninjutsu talent; on the battlefield, he was still just cannon fodder. "What a piece of trash system! If other transmigrators told me, they'd look down on me, thinking I can't afford a good system." [Completed healing Uchiha Mikoto, reward: one golden magic orb.] [Congratulations on obtaining a magic orb.]

My name is Fujiwara Seiji, a transmigrator. What I love most isn't saving the world, but admiring the helpless yet beautiful sight of those arrogant heroines falling into the abyss. When the black-stockinged upperclassman, Kasumigaoka Utaha, took off her stockings in front of me for three million yen in surgery fees. When the blonde loser, Eriri, knelt down begging me to invest in her dreams. When the icy beauty, Yukinoshita, walked into my room to rebel against her family. Only then did I realize how interesting this world truly is. Hero? Savior? No, I just want to be a… behind-the-scenes mastermind who controls the heroines. [Friendly Reminder: The protagonist of this book is loyal to his own desires; those with a saintly heart should avoid this!]

Lin Feng transmigrated to the Douluo Continent, only to find himself transformed into a soul beast with no strength whatsoever, except for his cuteness. Fortunately, during a foraging trip, his cuteness earned him a Saintess, Bibi Dong, as his human servant. Having died from overwork in his previous life, and finding the outside world far too dangerous, Lin Feng, after awakening the "Idle Fish Sign-in System," became increasingly lazy and irresponsible each day! Who would have thought that Bibi Dong could hear Lin Feng's thoughts? "Little Fengfeng, give me a hug!" [A little tighter, hug me tighter!] "Little Fengfeng, a maid brought over a bowl of soup. Do you want to drink it together? After we finish, we'll go see our teacher!" [Shapi, what are you drinking? That's a sleeping potion! If you drink it, you'll be waiting to be... you know... done to you by your beastly teacher!]... Bibi Dong: "Little Fengfeng, you're truly a lucky star for our Spirit Hall!"

Nalan Yanran, who had wanted to annul her engagement, was always eager to marry him. Ya Fei, whose cultivation talent was mediocre, performed the Xuanbing Dragon Soaring in front of him.

Feng Qing'er, who discovered she possessed the Ancient Phoenix Blood Essence, took out the corpse of a senior she had stolen from the ancestral tomb of the Heavenly Demon Phoenix Clan and asked if it was enough.
