(100 chapters in, changed the introduction, no free girl, no random CP, the main plot is the girl band, as for some comments in the book review, I am too lazy to refute them, I have explained it to you, you can judge for yourself)

What happens when a geek travels to the world of anime?

"Eri, believe me, confession will definitely succeed. He's waiting for you!"

"Gui Qu Lai Xi Nu... Uh, that's not right, Miss Kita Kita, look at your Ryosenbei, it's actually been waiting for an opportunity!"

"Xiao Hongxia, actually, my book 'One Hundred and Eight Ways to Deal with Tsunderes'..."

"The lead singer is working too hard. If this is the bond between Kulaixiku, then Wadasi (ˊᵒ̴̶̷̤ ꇴ ᵒ̴̶̷̤ˋ)"

"Hey, I found another free meal today~"

Asukagawa happily interacted with the beautiful girls, feeling relieved as the plot gradually got on track. If it weren't for him—??? Nijiga, what's the meaning of that hand of yours? And Ryo, aren't you afraid that I'll ask you to pay back the money? !!! Kita, what about your love for Ryo? ...

Yamada Ryo: "After this job, I'll have a full meal every day~"

(There are currently four books tentatively planned: Road Girl, Lonely Rock, Mygo, and K-ON!) (There will be many Easter egg characters, but they are not the main characters. Just a funny picture. The main storyline is only written so much because the author is afraid of not being able to write enough. I am a new author) (The introduction is weak, please move to the main text)

Upon waking, Nobita finds himself sixty years behind in technology. In the town of Tsukimidai, all memories of Doraemon vanish along with the regressed era. After a series of twists and turns, Nobita and his friends learn the truth: an unprecedented, massive, and trans-temporal war is unfolding, its target the future where humanity's technology is booming. The dominoes hidden in the past have already fallen, about to form a colossal wave that will engulf every era of humanity. The only clue is a snapshot taken across time. On September 19, 1492, at the center of the temporal vortex, the Time Police captured a photograph of the back of a blue nursing cat-shaped robot. This becomes the catalyst for Nobita and his friends being drawn into this trans-temporal heist. As they uncover more and more clues across different eras, a massive conspiracy gradually surfaces.

"I want to become a shadow master."

With this dream, Sid, who was born in an ordinary real world, was reborn in another world, but found that this world was too peaceful.

Just when he thought he would never be able to become a true shadow master in this life, the world changed dramatically.

Demons, vampires, angels, and gods appeared in this new world one after another.

"Listen, this world is cheering for the birth of a shadow master."

Shadow said.

During an interview, Mizuki Yuu was hit by a truck and flew away. When he woke up, he found that he had traveled to a parallel world and turned into a child. He was picked up by a plump, mature and sexy older sister and taken in.

He thought he could live the comfortable life he had always dreamed of, but he found that this world seemed a little wrong!

The mature older sister who took him in was called Mizuki Shiranui, a Taiman Ninja. Shiranui's daughter, his non-blood-related sister, was called Mizuki Yukikaze. The new wife next door, Mrs. Shendong, was a snow girl. Did a classmate who had a good relationship with him suddenly become a succubus?

Someone in the school was holding a mobile phone and was ready to hypnotize all the girls with a software. The female knight of the demon world tried to seduce them to join the demon clan. In this somewhat broken world, Mizuki Yuu just wanted to protect the people around him and keep them from the covetousness of various yellow-haired people.

But they asked why they all relied on themselves one by one?

"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!!"

Good news: Nakano Yuri has received the golden touch of hard work paying off.

Bad news: This is just an ordinary world. I thought I was going to live a peaceful life as a dragon king, a literary master, or something similar.

But unexpectedly, he joined the multiverse chat group.

Thus, the worlds welcomed a great demon king who defied the heavens.

Give him a breathing technique, and he mastered it on the spot, innovated upon it, and won over Kanroji Mitsuri;

Give him a gentle punch, and he will master it on the spot, thus conquering Kaguya Otsutsuki.

Give him a Devil Fruit, and he immediately understands its essence and masters countless fruit abilities;

At the end of the cycle of hard work and perseverance, Nakano Yuri transcends multiple realms and becomes the strongest being in the world of crossover anime.

When everyone asked him why he had become so strong so quickly, Nakano Yuri replied, "You reap what you sow. Just work as hard as I have!"

(Currently, the world's most popular anime and manga series include One Piece, Naruto, Demon Slayer, Date A Live, and Konosuba.)

Su Yun, a five-star fragile college student in his previous life, became one of the transmigrants who died suddenly because his graduation thesis did not please his instructor.

But why is the world I traveled through so strange? Hirano, the golden-haired loser, Pochi, it should have been a world of daily youth.

Until "Hello everyone, I am the transfer student Yotsuya Miko, please give me your guidance in the future."

After that, Su Yun's daily life became completely strange. Ghosts, ghost stories, demons, and ghouls became his regular visitors. The red Likolis even visited him from time to time.

What's worse is that before he awakened his past life memories, he had terrible interpersonal relationships. The green tea boy Aki Tomoya wanted to bully him in school because of his relationship with Kato Megumi. The seemingly sunny and kind Ohga Taiyo stabbed him in the back silently...

In response to this, Su Yun, who possesses the Sukuna template, said that there is actually only one problem that troubles him: on whose head should today's cursed fetus be assigned?

When Su Yun was in distress, an unknown classroom

Nishiki Chitsuka: Today is my day

Yukinoshita Yukino: We made an appointment to go see cats together

Yukinoshita Haruno: You can't compete with your sister, little Yukino

On the other hand, Kaguya Shinomiya did not speak, but only signaled Hayate to hand her the Quinque weapon.

Kato Megumi's red eyes flashed, and there was a faint movement behind her...

After crossing into the anime multiverse, the hidden world opened and monsters ran rampant. Just as Tsukikawa Shuu was about to embrace his slacker destiny, he discovered his golden finger was... marriage and offspring?

"I, Tsukikawa Shuu, despise the scourge of impotent protagonists! I categorically reject the toxic trope of 'flirting without commitment'!"

...

Gotou Hitori: "Eh? I'm... married? Well... I was never good at saying no anyway..."

Kitagawa Marin: "Marriage? Haha, sure... Wait! You're actually serious?!"

Fujiwara Chika: "I-It's not like I had a choice! But don't let the student council find out about this!"

Yukinoshita Yukino: "You want my hand? First take down that ridiculous 'Wanted: Wives' advertisement!"
