Zuo Zigong traveled through time.

Liben has traveled to a parallel universe.

He transmigrated into the body of a handsome Chinese man studying in Tokyo.

In this special parallel universe, there is Shuchiin High School, Sobu High School, Itomori Town, Shinomiya Foundation, the End Band, and many, many other things that once only appeared in anime.

This seems like a good start?

However, at the same time, Zuo Nong also received a legacy from an extremely ancient civilization.

From this legacy, Zuo Zigong learned...

The world-destroying monsters are about to arrive one by one, and he will need to transform into the final giant to fight them.

Upon arriving at the Advanced Nurturing School, Kirino Doppo awakened the Popularity Character System. As long as he performs well in the eyes of the audience, he gains popularity points, which he can exchange for abilities in the system's shop. To gain even higher popularity points, Kirino Doppo decided to cultivate his persona. Mysterious: He always speaks in half-truths and is a riddle teller. Kind: He lends a helping hand to those in trouble, even if it seems foolish to outsiders. Powerful: He uses popularity points to frantically enhance his combat strength, reaching a point where he can easily defeat Ayanokoji Kiyotaka with one hand. Over time, whenever the audience sees Kirino Doppo appear, they can't help but exclaim, "Everyone, come quick! The real protagonist has arrived!"

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...

(The story is set after the events of *Eyes of Heaven*, where the JoJos fall into a strange space and are unexpectedly drawn into a world mixed with slice-of-life anime. What follows is the story of the JoJos causing trouble in these slice-of-life anime. For readers unfamiliar with the *Eyes of Heaven* storyline, this can be understood as an ending where all characters from parts 1-8 survive.) They finally defeat "Heavenly Dio," but after Dio's death, the timeline seems to have taken a strange turn due to everyone's battle. Jotaro Kujo: "...What's going on?" Looking at the skyscrapers in front of him that are completely different from his memories, and the fact that it's 2018, everything seems so unfamiliar. However, Jotaro later discovers that he's not the only one; many others have also been unexpectedly caught up in this "farce." Jonathan: "In short...is this another parallel world...?" Joseph: "Oh! NO! What on earth is going on?!" Jotaro: "...Yare yare thief!"

Sun Baihe time and again traveled through time, searching for his way home. He had once teamed up with Asuna in Sword Art Online, their combined swordsmanship reaching the top of Aincrad; he had also used his 3D Maneuver Gear to slice through the nape of a giant's neck in the world of Attack on Titan; he had studied magic at the Clock Tower, only to be unexpectedly swept into a time warp, returning thousands of years to teach Artoria how to govern; he had shared drinks with Whitebeard, and later single-handedly conquered Mary Geoise, the holy land of the Celestial Dragons, ending their rule; he had debated swordsmanship with Retsu Unohana, experienced Sosuke Aizen's Kyoka Suigetsu, and dominated the world of Bleach, seemingly undefeated; he had even been slammed in the face by the White Tyrant, and became friends with her… After countless hardships, he returned to the main world, exhausted both physically and mentally, becoming a lazy bum who only wanted to rest for a few hundred years. But unexpectedly, the sixth wave of spiritual energy revival opened countless dimensional portals. Seeing familiar faces on the television screen, Sun Baihe shuddered. "Damn it, the debt collectors are here!"

"Do you know the correct way to use the Mystic Eyes of Death Perception?" "Precise attack lines and points?" "No, no, no~~~" The young man waved his hand and pulled out a rocket launcher from the cello case on his back... This is a story that singles out high schools from various anime and game works, focusing on battles, "romance," battles, dark sides, pseudo-daily life, true apocalypse, and mutual sabotage.

The principle of 'quantitative change leading to qualitative change' proves this: as long as I fawn over enough heroines, I'll eventually be able to win over at least one of them. With this thought in mind, veteran simp Kitahara Kaede went further and further down the path of simping, only to find, upon looking back… that all the heroines were actually secretly in love with him?

Tokyo. Inside an apartment. A handsome young man stood silently before the bathroom mirror. Not long ago, inexplicable memories flooded back. Now, he had completely absorbed them, realizing he was no longer in the same world. There were no more dump trucks, no more divine favor.

Transmigrated Cang, possessing a flint-wielding left eye that awakens a magical world, uncovers a cosmic truth with his cousin, Shenxue: Earth is actually a prison for alien gravediggers, and Shenxue's family bloodline is a container for a spiritual virus. The two break through seven cycles of reincarnation, discovering that the world is actually a fairytale manuscript from a higher realm. Ultimately, they tear apart the shackles of narrative, wielding the silver-haired flint-wielding pen to rewrite the laws, transforming bronze doors into bookshelves, and the gravediggers into footnotes to the fairytale.

Chen Zhen traveled through time and became a teacher named Yoshizakikawa in a Japanese school.

At first, he thought it was normal.

Until he found out that the girl who was bullied by his original self and came to collect rent every month was named Kayako.

Moreover, there was a classmate named Tomie who was flirting with him in a university class.

There is also a neighbor named Shirai, an autistic girl who doesn't like people calling her name.

There was also a transfer student named Sadako Yamamura who came to him one day to apply for a scholarship.

He was lost in thought;

Anyway, it's like this, why not have some fun?

"Kayako, Tomie, Sadako, let's play with the Pen Fairy!"
