Sky Curtain: An Initial Overview of the Immortal Lord of the Myriad Laws of the Mortal World

Above the sky, images and text about Ji Ku slowly unfold, his honest appearance and calm inner self creating a subtle and thought-provoking contrast.

In 525 AD, Ji Ku, who had already attained great supernatural powers, with the help of the Lord of Penglai Island, calculated the time when the Myriad Causes Corpse Immortal would descend again, learning that the 27th War of Cause and Effect in history would arrive in 530 AD.

The world of Death Note.

In the dimly lit room, L sat on a chair with a lollipop dangling from his mouth, his eyes fixed on the few words of information on the screen, a strange light gleaming in them.

"A calculation... a five-year prophecy," L mumbled indistinctly. "This isn't a guess based on probability, but a precise calculation involving the variable of 'Lord of Penglai Island.' What exactly is this 'help'? Is it providing some kind of observational equipment ahead of its time, or does it inherently possess the ability to foresee the future? This Jiku, able to draw such accurate conclusions using this information, his information processing and logical construction abilities are very interesting. If I put him in the Kira incident, would he be my ally, or another, more troublesome opponent? He must be listed as a top-level observation target."

The world of Code Geass: Lelouch of the Rebellion.

Inside the command room of the Black Knights, Lelouch Lamperouge rested his chin on his hand, a triumphant smile playing on his lips.

"Five years ahead of schedule... a full five years!" Lelouch's eyes gleamed with excitement. "This isn't just a tactical advantage; this is absolute intelligence capable of overturning the entire strategic landscape! Five years is enough time to train an elite force, to stockpile enough resources for several decisive battles, to win over key figures within the enemy ranks, and even to manipulate public opinion, plunging the enemy into a people's war before they even appear! This Ghibli holds not just a date, but a key to victory. If it were me, with just this one piece of information, I could set up a game that even the gods couldn't turn around. Checkmate!"

In 530 AD, Jigu, merely by observing the numerous fluctuations in causality within a single day, deduced that the person who had attacked his master with a death wish likely believed that this frequent fluctuation of causality would once again threaten the annihilation of Wanye. Furthermore, Jiang Mingzi's escape from causality in the Bored Valley allowed him to accurately determine that the successor had been chosen from three different time periods within the same month, marking a decisive step towards eliminating Wanye.

The world of No Game No Life.

In the room of the "Blank" siblings, Sora and Shiro sat side by side, their eyes both gleaming with an all-seeing light.

"Hey, Bai, did you see that?" Kong excitedly pointed at the screen. "This chain of logic is brilliant! First: 'Causal fluctuations' is the known premise. Second: 'The assassin is prepared to die,' indicating that their target is extremely valuable and the opportunity is fleeting. Third: 'The master avoids cause and effect,' which is an abnormal behavior and must be related to the premise. Fourth: Connecting these three points points to the only solution—'A decisive event that could threaten the final boss, Wanye, is happening!' And this event is naturally the gathering of 'successors of the Same Month Order'! Wow, that's amazing! This guy's way of thinking is exactly the same as our thought process when playing puzzle games! It starts with the end in mind, eliminates all impossibilities, and whatever remains, no matter how outrageous, is the truth!"

Bai Xiaoxiao nodded, and said succinctly, "...NICE."

The world of "The Pharmacist Girl's Monologue".

In the inner palace, the cat was squatting on the ground observing herbs. Hearing the sound from the sky, she looked up, an expression of interest on her face.

"Oh?" She dipped her finger in the medicine and put it in her mouth, saying thoughtfully, "Deriving motives from phenomena, and then combining that with the actions of key figures to deduce the essence of the event. Isn't this a common trick in palace intrigue? Except, he's not dealing with jealous concubines, but with a matter of world survival. He can smell the conspiracy from something as ethereal as 'causality,' and he can even calculate the assassin's psychology and his master's movements... If this man named Ji Ku came to the harem, even Lord Ren would probably find him troublesome. His mind is too meticulous, like a spider web; no slightest movement can escape his eyes."

[During the nationwide celebration at the First Dharma Palace, when Ying Xingguo was enjoying his homemade wine, Ji Ku, with heartwarming kindness, presented Ying Xingguo with the celestial wine bestowed upon him by his master, fearing his junior brother would feel bad about it.]

The world of Natsume's Book of Friends.

Natsume Takashi was sitting on the veranda with Nyanko-sensei when he saw this scene, and a gentle smile appeared on his face.

"Nyanko-sensei, look," Natsume said softly, "In a world full of battles and conspiracies, there are still such heartwarming moments. That bottle of wine must have been very precious, but he gave it to his junior without hesitation. This kind of unspoken care is more touching than any fancy words. It's because of companions like that that we can persevere in despair. Just like I have everyone by my side."

Nyanko-sensei wiggled his round body and snorted, "Tch, it's just a bottle of wine, it'd be more like a steamed bun from Nanatsujiya! But this kid named Yoshiku does know a thing or two about social etiquette."

The world of "Under One Person".

Zhang Chulan stared at the screen, a signature, slightly shameless smile on his face, but his eyes were serious. [3, 5, 8]

"Wow, look at that, now that's a real master." He clicked his tongue. "He looks honest and reliable most of the time, but when it really matters, he's quick-witted. And that's not all, he knows how to win people over. That wine-giving move was brilliant! It made his junior brother look good, showed his generosity, and deepened their friendship. If he were in a company, he'd definitely be the kind of person who could unite all his colleagues and eventually become a department head. Bao'er, you see, learn from this. Don't start using 'Awei's Eighteen Styles' right off the bat. Sometimes a bottle of wine is more effective than anything else." [3, 5, 8]

Feng Baobao munched on her apple expressionlessly: "Oh, so next time I bury someone, I'll bury a bottle of wine too?"

[When facing Sui Yuan's army descending from the sky, Ji Ku was able to calmly analyze the enemy's intentions in the critical moment, stopping Jiang Tong and Hai Hua Yao from their mindless charge. Although her attack power was not as eye-catching as Senior Sister Jiang Tong's, it was still not to be underestimated.]

The world of Naruto.

In Konoha Village, Nara Shikamaru yawned, his face showing a "this is so troublesome" expression, but his eyes were full of admiration.

"Ugh... honestly, why does every team have this impulsive guy?" He scratched his head. "But that's precisely why this guy named Yoshiku is so precious. In that critical moment when a massive enemy force is pressing in, he can still hold his teammates back and analyze whether the enemy is coming for a 'sneak attack' or a 'frontal assault.' That takes incredible composure and judgment. Compared to those idiots who just shout 'Charge!', this kind of person who can keep the team alive is the real core. I really want to play a game of shogi with him; it would be so interesting."

The world of Attack on Titan.

On the city wall, Armin Arnold clenched his fists, his face filled with empathetic excitement.

"That's it! That's it!" he whispered. "True courage isn't about recklessly facing death, but about maintaining a clear head when everyone else has lost their minds! Stopping your comrades' impulses is harder than personally slaying a hundred giants! He used his wisdom to avoid a trap that could have thrown his side into chaos. He was the key factor that tipped the scales on that battlefield!"

[After Jiang Tong was punished for using the Mingzi Talisman, Ji Ku followed suit, taking the Wan Ye Fruit from the world previously imprisoned by Wan Ye and sending it into space, thus also suffering a punishment under the law of cause and effect.]

The world of Fullmetal Alchemist: Brotherhood.

At Central Command, Colonel Roy Mustang stared sharply at the sky.

"The second one...?" he murmured. "This wasn't just imitation or impulsiveness, but a tactical continuation. The first person was responsible for breaking through the encirclement, drawing the main fire, and bearing the initial punishment. And he, as the second echelon, precisely seized that opening and accomplished the final objective. For this, he willingly accepted the same cost. This isn't recklessness; this is the decision only a soldier with the resolve to die could make. It deserves respect."

The world of "Wuxing Mountain's Fog Mountain Journey".

Wenren Yixuan watched the figure rush into space, his eyes filled with complex emotions. He thought of the pain and shackles he had endured to protect his village.

"Bearing the punishment brought down by the laws of the world... this is the destiny of a guardian." His voice was low and hoarse. "He knew very well what he would face, but for that 'fruit,' for the hope of the future, he did not hesitate for a moment. This kind of resolve is not something everyone possesses. He and his senior sister are both warriors worthy of respect."

[In the Mingzi battlefield of the thirty-eighth Bingo Battle, facing the combined power of the Wilderness transmitted by the Myriad Realms Mirage, Ji Ku analyzed that the enemy was also giving his future comrades a chance, knowing that the enemy's supernatural powers would not last long in this era. He conjured a giant King of Soldiers and went all out.]

JoJo's Bizarre Adventure: Battle Tide Arc.

Joseph Joestar slapped his thigh and let out his signature laugh.

"OH MY GOD! I knew it! This guy's a genius!" He pointed at the screen and excitedly shouted to Caesar beside him, "See that? That guy called 'Fusion Ara' looks ridiculously strong, but he saw through the opponent's weakness at a glance—'Time Limit'! Just like I knew the Pillar Men would be finished in the sunlight! This ability to find the opponent's weakness in a desperate situation is the strongest tactic! His next line will definitely be: 'Your performance time is running out!'"

[Furthermore, after defeating Huang, he rode Jiang Tong and relentlessly slaughtered Wanye, awaiting victory on the future battlefield.]

The world of Gintama.

Inside the Yorozuya, Sakata Gintoki was picking his nose with his little finger. Upon seeing this, Gintoki almost flicked his boogers away.

"Hey! What are you talking about?! What is this? A post-final battle ride?" Gintoki exclaimed with all his might, "That usually calm guy with glasses (even though he wasn't wearing glasses) is riding that crazy senior sister around hacking people to pieces? And that senior sister is in dragon form? Isn't this just treating a berserker like a motorcycle?! What kind of god-like combination technique is this? Gintoki, why didn't I think of turning Kagura into a gorilla and riding her to collect rent? Shinpachi, you should learn from this, this is the perfect combination of wisdom and strength!"

Shinpachi Shimura pushed up his glasses: "Gintoki! Is that the point? The point is they actually treated the final boss like a regular enemy! Also, please don't compare Kagura-chan to a gorilla so casually!"

The world of Assassin Seven.

In the hair salon on Chicken Island, Wu Liuqi stared at the screen in disbelief as he got his hair cut.

"Wow! Flying on a person? And it's a dragon!" He was full of envy. "This is way more exciting than my little flying chicken! Look, look, that calm guy is in charge of commanding, and that dragon girl is in charge of hacking and slashing. They work together so well! This is the best team! Chicken Da Bao, shouldn't we also study a combination skill? Otherwise, next time we encounter a strong enemy, I'm afraid I'll be beaten back to my original form again."

The world of "The Daily Life of the Immortal King".

Wang Ling ate his instant noodles expressionlessly, analyzing the situation without any inner turmoil.

"Hmm, highly efficient tactical coordination," he thought. "Physically binding the most analytical 'brain' with the most destructive 'weapon' reduces communication costs and reaction time, achieving a 1+1 greater than 2 effect. Although the visuals are somewhat... unconventional, judging from the results, it's the optimal solution given the current resources. It's worth learning from."
