Crossover anime, crossover anime, crossover anime!

Although it's a crossover anime, it's so crossover that even the author doesn't know how to describe it. All I can say is that the author will probably write about the characters you want to see in the future.

The story will begin with GBC as the main plot, and other anime plots will gradually be introduced, such as Oregairu, Lonely Rock, and Lost Children. There are also some other anime whose main plots have ended, but they will be continued in this novel.

Don't worry too much about the location and time. The protagonist isn't Superman; he can't fly from one place to another every day or travel through time.

Multiple female leads, and other anime male leads with gender swaps, so just obediently endure the protagonist's abuse along with the female leads.

There may be out-of-character (OOC) content; please do not read if you mind. Thank you.

Tennoji Kaede enrolled in Advanced Nurturing High School and successfully awakened the Gray House Karma System!

The more you are tainted by the 'cause', the more 'effect' he will give back!

"Gray House, add some points!"

Afterwards, Tennoji Kaede was assigned to Class C and formed a partnership with Ryuen Sho.

From this moment on, the unbeatable King Class C was officially born!

......

"Ayanokoji Kiyotaka? The White House is just a masterpiece, but can you beat my Gray House's supreme martial arts?"

"Yamachi Haruki? The Black Room is the supreme masterpiece, but I, Tennoji Kaede, am willing to acknowledge you as the strongest underground!"

"Longyuan, please believe me, I have absolutely no intention of using you as a tool!"

"Besides my little angel Hiyori, are there no decent girls in the actual class?"

......

Time flies, and three years later, it's graduation time.

The ultimate strategy that Tennoji Kaede decided upon entering the university has been achieved!

He ultimately became a legend of practical education and high moral character...

"We Can't Learn" + "The Quintessential Quintuplets" + "The Dry Girls" + "The Shura Field of Girlfriend and Childhood Sweetheart"...Emperor Hayakawa is undefeated in his life. Hayakawa, who has been planning for a long time and aims to be the top student in both subjects, was defeated by two geniuses in the arts and sciences in their respective fields? How can a man like me bear this humiliation? I must humiliate them severely! ... "The fastest way to affect the other party's grades is indeed "premature love"~" Hayakawa Bai Rushi said. However, these two have not been dealt with yet, Doma Mai and Natsukawa Makoto, one after another difficult-to-beat strong enemies appeared. How difficult is it to be the first place... This book is also known as "You who are obsessed with love can't study with me"

Practical training, system, self. Should good people be held at gunpoint? Ichinose Honami, help her. Should those who try to put out a fire be left to freeze to death in the snow? Hirata Yosuke, help him. You hold my sincerity, saying it's your winning chip? Sakura Airi, help her. Her heart has just warmed when she encounters the harsh winter of Karuizawa Megumi, help her. Maybe a little out of character, after all, my heart leans left.

What's it like to form a band? What's it like to be a "normie" (a person who is successful and popular)? Kusano Akira felt he had some authority to answer these questions. Although some unpleasant things always happened after forming the band, he managed to resolve them all without major incidents. For example, a beautiful celebrity was possessed by a strange, earthbound spirit; a flaxen-haired, love-starved girl living in the same building wanted to sabotage the current band and reunite with her old bandmates; a quirky girl in his class had been secretly recording his affairs in a notebook; and the pink-haired, socially awkward girl from the neighboring band plastered her room with inappropriate photos—although his instincts told him something was off, he managed to handle all of those situations satisfactorily. For someone making friends for the first time, Kusano Akira felt he had done a pretty good job. It's just that his friends have been looking at him strangely lately, as if something dangerous might happen at any moment—probably just his imagination. "Aine, what are you doing here? How did you get into my house? What are you doing with that rope? Is it some new game?"—[Male protagonist story, harem]

For the stability of the world, Ito-kun, please date me!"

Youth is both a lie and a sin.

For those who sing the praises of youth, lies, sins, secrets, and failures are just the seasoning of youth.

If failure can be regarded as youth, then those who fail in making friends can also be said to be enjoying their youth, right?

Therefore, the helpful Matsueda Azusa decided that

he would help all the current students enjoy their youth!

Campus lovers with a sour smell, please keep an eye on your partner…

Matsueda Azusa is coming in!

Everything seemed to be heading towards the pinnacle of life.

But everything changed after one game.

"What? Zeus and Murumuru, you are not creatures I created, you are real beings?"

"What? The death game actually happened?"

"What?! My girlfriend in the game is actually Yuno Gasai, the queen of the yandere world?"

Backed into a corner, Amano Kazuki asked the pink-haired girl wielding the axe with trepidation, "Yuno, can't we... break up peacefully?"
