Higashino Yuu never imagined that the "cognitive reconstruction" ability he awakened after traveling to Academy City would become the ultimate cheat for building a harem. Saying "You're a little attracted to me" to Misaka Mikoto makes the Railgun's cheeks turn red as ripe apples. Mummifying "You want to understand me" while locking eyes with Shokuhou Misaki makes the Tokiwadai Queen's remote control quietly aim at him. Even a saint like Kanzaki Kaori can blush at the mere suggestion of "Come see me tonight." From Judgment Officer Hatsuharu to ANBU TEM's Mugino, from the mage-minded Index to the one-eyed demon god Othinus... If he so chooses, rewriting the perceptions of girls and making them utterly devoted to him is a matter of thought. Higashino Yuu held his forehead, looking at the group of beautiful girls surrounding him, sighing with both helplessness and excitement, "I told you not to push... Okay, whoever kisses me first, I'll be theirs tonight." This is the story of a man who uses his powers to forcibly conquer every goddess in Academy City, turning his "harem" into a "settings manual"—after all, for him, making beautiful girls fall in love with him is easier than unscrewing a bottle cap. PS: This book is more about daily life, with more peach plots in the later stages. I'm not a fan of meticulous research or rigorous settings, so please don't criticize me if you mind.

"Yandere," "Girl Army," "Absolute Enslavement," "Villain," "Dual Heroines," "Vampires," "Apocalypse"

The obedient girl Su Mu in ordinary days has a rebellious personality and unusual sexual orientation, like a devilish, yandere little devil.

As the apocalypse descended, Su Mu, favored by the progenitor of the vampire clan, became a vampire demon princess, gaining vampire power and the psychic talent "Absolute Slavery".

Look down on my aloof and cool female disciplinary committee chairperson? Please play some "girl games" with me under my absolute subjugation!

Note: The female lead, Su Mu, is not a saint! She might do some inhuman and crazy things! Be prepared!

(P.S.: Due to the invasion of an alien god during the apocalypse, which caused a spacetime distortion, some familiar figures from the world of anime and manga may appear in the book. Don't be afraid of DNA mix-ups! "Anime and manga appearances will not affect the reading experience~")

Travel through a world invaded by disasters and awaken the sign-in system of all worlds.

He thought that signing in in this world and obtaining the power of a Ruler of Reason, which was enough for him to protect himself, would be great enough.

Unexpectedly, he was selected by the dimensional chat group and got the opportunity to sign in to other worlds!

I originally wanted to head towards the end of the trees and the sea, but I found that I met countless beauties in the process.

Kasumi no Shi: "Tsk, what an unlovable leader!"

"You left a deep impression by being a hero saving a beautiful girl, but now you want to just walk away after you've been seduced?"

Eriri: "Damn it! I was here first, and the twin tails were supposed to increase attack speed! Why don't you come up and attack!"

Esdeath: "This man is stronger than me. I can't match him in terms of strength, but I must conquer him in other aspects!"

Lei Movie: "He saved his sister, if he wanted to..."

After traveling through time and space and becoming a Fader, he broke through the borderland and brought the petite Lani with him to the world of anime again. Here, the King of Elden began his new life.

Before today, Mo Li had considered himself quite successful as a time traveler! Despite his strange titles like "the company's hottest idol" and "honored guest of the Immortal Boat Alliance," Mo Li knew that everything he had achieved was entirely due to his own hard work! However... "System! Didn't you promise me the simulated universe was fake?" Mo Li trembled as he looked at the women, their eyes glowing red, gradually approaching him. [This...that...Hey!] As expected, the Maomao system was unreliable!

(Slow heat + time travel + previous civilization + Mei Yi single female lead + main plot)

"Haha, I found you, Mei!"

Mei pouted in frustration: "Oh, you found it."

"I have 'Mei's radar', I can find you no matter where you hide~"

"I don't believe it unless we play another round!"

"Okay, let's play another round. This time I'll count and you hide."

......

"You said...you wouldn't lie to me..."

"You...big liar!"

She held the photo tightly in her hand, as if it was her only support.

"You said... you would come back... you said..."

"Achen...where are you..."

......

He promised everyone that he would bring back the girl who was as beautiful as a flying flower;

He promised everyone that he would try his best to leave more fire for mankind;

He promised everyone that no matter how much it cost—

Humanity...will definitely defeat the Honkai!

Alicia: "Oh, Xiaochen, you are so cute. This pink skirt must suit you very well! Oh, don't run~"

Mei Lei: "Su Chen, I am willing to fall into darkness in exchange for you returning to the light, just like you once saved me."

Xilin: "Brother, you said you would stay with me forever. This time I won't let you leave my side again."

Lin Zhaoyu: "Big Brother, do you remember that you still owe me a promise? I am willing to spend my life with you."

The Herrster of Knowledge: "Traitor, come and take my sword!"

After being transported to another world, Mizusaki Yuuma looked at the newly released "Love Metronome" and realized it was a sweet slice-of-life romance anime. However, he encountered a girl collecting Clow Cards, a pile of scrap metal collecting the Peace Star, and a Sherlock Holmes from the Heisei era. He also occasionally heard urban legends about Tomie. Fortunately, his Yorozuya (Odd Jobs Shop) always attracted strange customers who traded things from other worlds with him. There was the Battlefield Rose from the ninja world, a rebellious girl from the world of navigation, a fox spirit from Valoran, and a girl visited by eight million warriors. Kasumigaoka Utaha: Hey, you have to take responsibility! Kinomoto Sakura: My brother is so nice, he helps me collect Clow Cards. Irelia: Grandma always says... Mizusaki Yuuma: Stop nagging Grandma, when are you going to pay back what you owe? In the corner, Mai Shiranui, remembering she still owed money, was trembling. ...

(Funa) Fu Yue accidentally came to the continent of Teyvat and found herself lost in thought. She became Finina. She was familiar with the plot and knew that Finina was just an ordinary person. In the final judgment, Fukaros died and gave all his power to Navilette. Navilette also prevented the disaster, and her drama of pretending to be a god also ended. However, Fukaros sentenced himself to death in advance for some reason and gave all his power to Finina, not Navilette.

Thinking of the end of Fucaros, Finina thought: It's over. The disaster was finally resolved by Fucaros giving his power to Villette. Now Fucaros is gone, which means that in the end I will also return the power to Villette, which proves that I will also be gone.

Fernina: Fukaros, I hate you! Why give it to me and not Violet? I don't want to die!
