A most mysterious organization has emerged on the mainland – "Akatsuki".

No one knows who its leader is; all that is known is that its members are all monsters.

The runaway prince is being hunted down by the Tsukuyomi ninja "Uchiha Itachi";

An impregnable fortress was reduced to ruins by the art demolition expert "Deidara";

The ruler of the deep sea was slain by the tailless tailed beast, Kisame!

As for me, Ye Chen, the creator of "Akatsuki," I simply watched calmly from behind the scenes as my reputation soared.

"My chess pieces are now scattered throughout the world."

The Dead Apostles are weakened, but not completely destroyed. Victor, a time traveler determined to become a great magus, is unexpectedly forced onto a path he never imagined. He is branded with the curse of the First Embrace. "I'm helpless to have to switch sides like this," Victor said helplessly, his hair in his hand, a look of pain in his face as he looked towards the "superior" in the corner, who looked menacing and threatened to kill him at the slightest disagreement. "Speaking of which, how did you, the dignified True Ancestor of the Dead Apostles, a true princess, end up like this?" ... ... ... A semi-game system: The protagonist's innate abilities (source) are [gamified], and as they increase in ability, they unlock features including maps, dungeons, team formations, and even a card drawing system. A semi-time travel system, the dungeon system includes simulations of major events, gates to other worlds, and challenging powerful enemies. Semi-invincibility, a common trait of some authors, emphasizes logic over brute force, and small setbacks are sometimes the product of a greater purpose. A semi-villain, the protagonist prioritizes self-interest, but doesn't mind showing a little kindness occasionally. However, he is not a saint, and is in the dual camps of the Dead Apostles and the Selfish Magicians.

I transmigrated and gained the power of a Stand, thinking it would be the unfolding of a shonen manga, but why is this world so peaceful?! Why am I, who's supposed to be feared by all four of them, living a peaceful life as a high school student?! Yukinoshita, don't think I really won't hit you! Kasumigaoka, can you please stop fantasizing about me being the male lead in your novel?! Shinomiya, I won't confess to you, give up! Waaah, Megumi is so much better, I need some comfort~

When mathematical genius Lin Xian opened his eyes, he didn't see a world of flesh and blood, but a rational realm flowing with formulas and data. Having traversed the world of cursed warfare, curses were no longer indescribable terrors, but chaotic equations awaiting deciphering.

"Style Reversal: Gödel's Incompleteness"

"The character '茴' in '茴香豆' (fennel seeds) has four ways of being written—while the curse of death has seventeen optimal solutions."

He pushed up his glasses at the super-grade cursed spirit that was devouring heaven and earth: "Your probability of existence is approaching zero."

He unfolded a draft paper over the tangled web of a thousand-year-old conspiracy: "There is a sudden change point in the entropy increase curve of your plan."

He even wrote a proof against Gojo Satoru's limitless technique: "The so-called infinity is nothing more than a romantic illusion of convergent sequences."

However, as the blood of Shibuya stained the mathematical model, and as the prison gates swallowed the last glimmer of light, Lin Xian finally discovered—

The deepest curse in this world is never the power of magic, but human nature.

The ultimate destination of reason may not be on paper, but in the wheat field growing beneath our feet.

This is the ultimate battle between reason and mystery.

[A hardcore epic that rewrites the rules of magic using mathematical formulas]

"When absolute rationality collides with the variables of human nature, the entire world of sorcery will tremble."

A newly opened antique dad shop in Yokohama.

You can always hear the old man crying out in pain.

One day, the kind-hearted Nakajima Atsushi passed by here and heard the sound of "Aiya" inside.

Is it okay for an old man to live alone? After entering, I found out that the old man has a black-haired, well-behaved, and good-tempered "grandson" to accompany him.

"Kaneki! Go make me some tea!"

"yes!"

[Vest: Jackie Chan Adventures Dad, Tokyo Ghoul Kaneki Ken.]

At the distillery, a new brewer codenamed Death Afternoon specifically requested that three bottles of whiskey be served to her.

Beautiful fingers with black nail polish pointed at Scotch: "I want you!"

Zhu Fu Jingguang:?

What do you want from me?

"Fall in love with me, Scotland!"

Zhu Fu Jingguang: ...

The other two bottles of whiskey were so hard to hold back laughter that they caused internal injuries.

[Vest: Death Note Misa Amane.]

In addition, there is the new physical education teacher at Teitan Elementary School, the ruthless and heartless new colleague in the Special Ability Department, and the cat brought back by Edogawa Ranpo from the detective agency.

[Avatars: Gintama Yato Kamui, The Seven Deadly Sins Gowther, Hunter x Hunter Neferpitou.]

Conan Edogawa: "The new teacher... feels more dangerous than the Black Organization."

I always feel like this guy will jump up and kill people at any time.

Ango Sakaguchi was silent: The new guy is so useful that I have nothing to do now.

Keep going undercover, it seems to be some code name winery

"Tags: anime, Shura Field, doujinshi" "Synopsis: 27-year-old Shizuka Hiratsuka no longer struggles with her lack of popularity with men. However... looking at the emails flashing on her phone, Shizuka Hiratsuka blinked. She seemed to realize that her popularity with women might be a little too good, right?"

Having unified Britain and established the Fairy Kingdom, Shirou returned to Japan in 1993. "Fuyuki, what a peaceful city..." Shirou thought he could live out his remaining years in peace, but then he encountered an unexpectedly familiar figure. "Morgan!! When did you get here?" The blonde girl exclaimed, "Just now some madman mistook me for Joan of Arc, and now... how are you going to confuse me with my sister? I'm King Arthur!" Shirou scoffed, "Laughable. You're King Arthur? Then who am I?"

As the fourth child of the Shinomiya family, I began living independently. Every day, I woke up in the dark closet, went to my bed, and took out a dummy, placing it under the bed. Then I checked the blades in the soles of my shoes to see if they were sharp, cleaned the potassium cyanide particles from my waistband, checked the prohibited words on my clothes, and made sure the miniature surveillance devices were working properly. I placed a bayonet in a book, and a submachine gun and bombs in my backpack. Completed, with a smile, I headed towards Soubu High School. As a normal high school student, I greeted a beautiful day. As a normal high school student, aren't the things I have normal?
