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..."

I'm a bipolar person who's been transported to Bang Bang's world. Friends tell me Bang Bang's world is a gentle place, and the band members are all bright, cheerful, and positive. I hope to make friends in this world, arrange songs I heard in my past life, form a band, and shine on stage, all to help me manage my illness.

Fujiwara Oboro is also a good kid in the eyes of others. He has excellent grades, is good at sports, and is willing to help others. He lends a hand to children who are bullied in school, hone his chess skills with the losing Naniwa Shirayuki, picks up the abandoned kitten and takes it home, and saves the heroine of "Transformation" who was going astray... Why, he only did some very ordinary little things. Since when, Oboro found that the heroines in the anime have all thrown themselves at him. The plan is successful~ (the protagonist is not a Japanese-style male protagonist, he is black-bellied, so be careful) (The world of anime, tentatively: Beautiful Girl Kaleidoscope, Rent-a-Girlfriend, The Dragon King's Work Is Not Working, Sword Art Online, How to Raise a Boring Girlfriend, My Youth Romantic Comedy Is Wrong As I Expected...)

Yuigahama Yui: For the first time, I found someone I liked and made a lifelong friend. These two joys intertwined...

(Currently implemented: Lonely Rock, Bangdream! It's My Go!!!!!) The idolization trend is sweeping the archipelago, and the light novel industry is no exception. At the behest of a school library, high school author Togawa Akie picks up her long-forgotten electronic keyboard skills, aiming to boost sales of her new work by forming a band. To achieve a more "original" commercial effect, the library doesn't assign her a permanent bandmate. Forced to leave the classroom and scour the streets for collaborators, Togawa encounters a group of girls who, under the name "End," are pursuing their dreams in a band. By chance, she and a girl named Chihaya Aine become entangled in Nagasaki Motoyo's scheme, ostensibly to form a band. "Perhaps everything originates from a fabrication woven from profit." "Then what is the meaning of these emotions and bonds born from this false heart?" (Tachibana, a fusion manga set in the world of idols and bands.)

[Everyday anime, many heroines, no pretentious and face-slapping plots, this article assumes that the heroine does not know those heroines] After traveling to the daily world of anime, Chiba Kitahara wants to live a plain and interesting life. But before achieving this goal, he may need to get along with the young lady for a while. After that, his daily life seemed to become less ordinary. A girl with a very low sense of presence invited him to appreciate the cherry blossoms not far away. The heir of a Shinomiya zaibatsu always told him not to work so hard. The cold girl in the service club also seemed to like to talk to him about life. Chiba Kitahara: I reiterate, my preference is mature older sisters, not young ladies! Protagonist: Chiba Kitahara

[Male protagonist, harem style, light comedy style] Whether we admit it or not, we have to say that being hated is a rather unpleasant thing. Sometimes you are liked by some people, but other guys will be unhappy. This is something that cannot be avoided. In Nakagawa Shin's opinion, there is no guy who is liked by everyone after all. To be honest, there is no problem, he does have good friends... and bad friends. And when things have changed subtly... For Nakagawa Shin, his "friends" seem to have not only forgotten their stories, but also become alienated because of various misunderstandings. What should he do? And for the girls at this time, it is obvious that the guy in front of them is the one they hate, the one they are unhappy with... but why

(Multiple female protagonists + Ayanokouji's gender change + romance + no entry if you don't like it) Hoshino Kanade is a time traveler who doesn't think she has many outstanding qualities. Although coming to Tokyo Metropolitan Ikusei High School was not her wish, it has come to this point, so let's eat first. (This is my first time writing fanfiction, please accept my first time)

"Kaguya" (it won't be the same as the original, after all, comics are history), "I got super powers in another world, but I am still invincible in the real world" (there is only a door, it doesn't delay reading), "Between Girls" (gentle god!), "Furuma-san has communication disorder" (shaky god), "The Girl I Can See" (add some fun), "We Can't Study Together", "Horimiya" and so on, and a little bit more.

After finally winning the family struggle, the Bai Chen family finally settled down to a life of despair. His parents went out to travel the world, while Bai Chen stayed to continue his studies. Why did he have to finish his studies?

Bai Chen: "Why do geniuses need to go to school? I want to travel around the world too!"

Father Bai: “No.”

Bai's mother: "Da Me Yo"

Bai Chen: "Why?"

Father: "We are worried about you traveling alone."

Mother: "But your father and I want to have some time for ourselves, so, Bai Sang, enjoy your college life."

Bai Chen: "Bagayalu!"

P.S.: It seems like the writing is getting more and more fantastical? I'm not going to stray into a battle story, am I?
