Humans and monsters should not be together, because in the end, it will only increase loneliness.

"I am human, and our encounter that day was the beginning of our relationship."

A certain Yukinoshita Yukino looked at Natsume.

"Junior, bunny girls are not monsters."

Sakurajima Mai smiled brightly.

"Natsume, quantum mechanics tells me that the feeling of loneliness will disappear as long as two people are together."

Futaba Rio was very serious.

"Brother Takashi, do you still remember our encounter at the beach that year?"

A certain blonde girl smiled.

A cultivator from thirty years after the resurgence of spiritual energy traveled through time and space to the body of a junior high school graduate named Chiba Nagisa in Chiba City, Japan. His parents were still alive, but he had no car, no house, and no younger sister. He simply became the landlord of a luxury apartment building. However, the residents were a bit strange: an angel lived on the left, a demon and a witch lived on the right, two dragons lived upstairs, a chuunibyou (a middle school student), and an immortal named Xiao Ming, whose wife was a monkey. He had a cousin who was a college student named Sekiguchi, no, it was called Nyanei, ugh! To be more precise, her name was Hoshino Miyako. He also had an otaku friend named Aki Tomoya, and a chuunibyou netizen online named Fallen Angel. This world should be a warm and everyday place, so how could there be these strange ghosts?

What does it mean to be meticulously planned? What does it mean to have countless schemes? This real estate agent is just a college graduate who, by some twist of fate, ended up in the world of a practical education school. Am I, a college graduate, really inferior to you bunch of little high school students? I can certainly manipulate people's hearts a little! But Ryuen Shoko, let me explain first. I really didn't flirt with girls from other classes; it was all part of the plan, for the plan!

At the beginning, he came to Japan in a parallel world and became a plagiarist relying on the vision of his previous life. However, his peaceful days were suddenly broken by an accident. Faced with the predation of ghouls, Lu Ziyuan could only sit at the dining table helplessly.

Kaneki: "Am I a human or a ghoul? I've decided, I'm a ghoul!"

Lu Ziyuan: "Are you sure? Then I won't be polite!"

Arima Kisho: "There's actually no difference between humans and ghouls. It's just that one is the open person and the other is the hidden person."

Lu Ziyuan: "I can prove it by ordering them. They all taste the same."

Muzan Kibutsuji: "Demons are higher life forms than humans, and I am the Demon King who controls demons!"

Lu Ziyuan: "High-quality ingredients often only require the simplest cooking methods, like tasting evil spirits in the sun."

I am Hachiman Hikigaya. My cheat ability is accessing the memories and experiences of Hachiman Hikigaya from other timelines. As everyone knows, I, Hachiman Hikigaya, am a workaholic in the industry, with countless identities: writer Hachiman, the son-in-law of heaven Hachiman, the son-in-law Hachiman, the magician Hachiman, the god-slayer Hachiman, the association agent Hachiman...

"That year, I saw the students of Class B slumped in their chairs, sobbing uncontrollably. That scene is unforgettable. At that moment, I thought, if I could become the class president of Class B, I would lead Class B to victory!" "So, Ichinose, let me be the class president of Class B." "No, Uesugi-kun, you're too radical." "Ichinose, you'll regret this!" "Uesugi, I am the class president of Class B." *Slap!*... "Hmph, naive Ichinose, do you think I can't do anything if you don't agree? Shibata, notify Kanzaki to prepare to close the net!" "Uh, um, Uesugi—" "Shut up, Shibata, this time we must act quickly. Before Ichinose can react, expel them from school. I want to see who can stop me this time." After a while, "The wind on the rooftop is so strong..." "Uesugi, come down quickly, I will never reveal your plans to Ichinose again." "You write it down!!"

Nakano Yu travels to a world where strength reigns supreme and becomes a highly trained freshman.

Good news: It's an anime he's seen before, he's a rich kid, and he has an ex-girlfriend named Sakuragi Arisu.

Bad news: He has five older sisters, but his father raised him in poverty and demands that he make a name for himself in high school!

He's been assigned to Class D? And it's already the end of the first month, and the class evaluation score is 0 points!

There are also a bunch of deadweights in the class.

Why bother trying? Just give up!

Anyway, I know the plot, so I’ll save up 20 million and just run away!

But.

Sakuragi Yū: Oh, so he’s in this school too. Then school life might still be worth looking forward to.

Ichinose Honami: Nakano-kun seems to have forgotten me, but I’ll try my best!

Kikyou Kishida: You're saying I'll be forced to sign something by a guy named Nakano Yu? And he'll make me drop out? Impossible, that's absolutely impossible!

Ichika Amazawa: It's true, Kikyou-senpai, just accept your fate!

Horikita: How unfair! On the first day of school, I was scammed out of all my points by a guy named Nakano Yu in my class.

Ryuen: The person above me, take it back. Let me speak. Nakano Yu, give me back three million! Three million!

Hikigaya came to the strength-first classroom. Because of his sister's request, he had to make ten friends before graduation.

For this slightly more difficult requirement, Hikigaya decisively chose the lying-flat approach.

"Air friends are also friends. Well, Komachi should be able to understand me."

However, three years have passed.

Horikita Suzune, Sakayanagi Arisu, Ayanokouji Kiyotaka, Kushida Kikyo, Karuizawa Megumi, Ryuen Sho, Koenji...

Looking at a group of people of the same sex and opposite sex who were staring at him covetously, Hikigaya fell into deep self-doubt.

Komachi, are these people really my brother's friends?

Miyuki Shirogane chose the tuition-free and fee-free Yusei High School over Shuchi Academy. After enrolling, he received assistance from his future daughters. As a freshman, all he had to do was study hard. But his daughters had much more to consider. Arisu's daughter: Anyway, I can't be the youngest this time! (￣へ￣) Shiina's daughter: I, I also want to help Mom! (＾～＾) Ichinose's daughter: I want to protect Mom and Dad's love! You runaway monsters! ??_?? Amasawa's daughter: If my mother hadn't enrolled so late, you wouldn't have had so much trouble! ?(????) Karuizawa's daughter: Oh well, I don't really have any presence anyway, it's good enough to see my young parents ヽ( ′?`)ノ. Kaguya's daughter at Shuchi Academy: ? ? Where the hell did my big dad go? Reborn Fujiwara Chika: Isn't this good too? At least I don't have to work so hard raising the kids anymore. Chika's Daughter: But then I can't be born! Chika: ??? Chika: Holy crap! ?

"Hello, have you ever been in a relationship?"

"Of course not." Tenkuji You shook his head, "I really have never had a girlfriend. If you don't believe me, ask my system. If anyone has the memory of being my girlfriend, I will lose, okay?"

"Then who are they..."

Tenkuji You turned around and saw Yukinoshita Haruno, Yuuki Asuna, Natsukawa Mansu, Yukinoshita Yukino, and Kasumigaoka Utaha walking over, with an expression on their faces that they wanted to settle accounts with him.

"Xiao Youyou, I remember that you left me in the hotel without permission."

"You-kun, I said - I will not forget, I will definitely think of you, and I will never forgive you!"

"Ayou, lovers will be punished by the three pages of Ora... Are you ready?"

"Tenkuji-kun, before you break up, you and I are still boyfriend and girlfriend."

"The heroine loses her memory, the hero leaves... I don't like this old-fashioned stomach-ache plot, Youyou-kun."

"... Something is wrong with you."

Tenkuji You looked calm, but was panicked inside, and was ready to run away.

"System, come out and explain yourself!"

"Meow."
