Summer sunlight streamed through the window, casting window-shaped dappled patterns of light on the quilt. A slender hand reached into the sunlight, seemingly seeking its warmth. The hand was very white, not a rosy white, but a sickly pale one, seemingly even whiter than the white quilt. Looking around, everything was as white as ever. There were no decorations, only a simple cabinet.

As a perfectly healthy high school boy, Sakuta discovers he's been chosen by a puberty syndrome. His symptoms are rather unique; he can enter the light novels he's read and complete special tasks to earn rewards. Is this for real? He immediately reaches into the merit-based classroom. [Confessing to the villainous female supporting character Kikyo Kushida in front of the heroines Karuizawa Megumi and Ichinose will earn him the "Ashore Illustrator" skill.][Grabbing Shiina Hiyori's twin tails from the bushes will earn him the demon sword Murasame.][Taking revenge on Sakayanagi Arisu for stealing your dog, sharing her gaze while watching a pink app for 2 hours will earn you…] "Hey, Futaba, don't look at me like I'm dirty." "This is a mission, not my XP!"

Hoshikawa Taku, who traveled to Japan due to the sudden death of his black-hearted boss's "PUA", was bound to the [Black-hearted Agent System]. The more "black-hearted" he was to the girl idols he signed, the better rewards he could get. So... he signed Toyokawa Shoko with a black-hearted contract with no base salary and 90% profit sharing. He signed Hiroi Kikuri with a contract of "free food, accommodation and enough alcohol". He signed Takamatsu Tomo with the condition of "forming a band for life". He signed Hoshino Ai with a verbal contract of "teaching you what love is"... When they learned about the contract conditions, all the girl idols scolded him for being a black-hearted agent. But when Hoshikawa Taku pushed the contract in front of them, they signed the contract honestly one by one. There was no way, who made him offer conditions that they could not refuse... Hoshikawa Taku said: I am the one who lost money by signing with you, and every penny of hard-earned money I earned from you is what I deserve!

Sincerity is paramount, Takagi Akito admires him immensely, Kashiwagi Eri and Eromanga idolize him fervently, Shiina Mashiro and the Fallen Saint Kuroneko insist on becoming his apprentices… He's hailed as a once-in-a-millennium genius, a prodigy kissed on the hand by the god of manga, but in reality, he's just a soulful artist like ONE. So why is he able to create such popular and critically acclaimed manga? It's simple: he traded his life for it. Of course, besides manga, you can also trade for girls, but that depends on popularity. So—Headhunter, don't come any closer! [Lazy Lin]

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...

After traveling to a strange world, he found himself imprisoned in a cage of the Goblin tribe.

After escaping with the help of the golden finger, he thought he would be the protagonist of this world, but he found out that the real protagonist was the Bone King who fought wits and courage with the air...

(Grand Blue + Date A Live + Oregairu + ...)

Looking at the dilapidated Yorozuya before him, Tengu Ginyu fell into deep thought...

"Why are there still weirdos in this world?!" Tengu Ginyu put the Time Driver into the Four-Dimensional Chrysanthemum, plopped down in a chair, and burst into tears.

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.

In short, this is an orange-colored story of an endless stream of search, fight and retreat (with average elements). ps: (It is essentially a bloodthirsty endless stream, with many combat elements and average search, fight and retreat elements. The proportion of light-hearted comedy is smaller than the bloodthirsty plot. The essence of the plot is still ruthless killing and crazy teeth.)
