[Dark-Dark Fruit, Demon Void, Mythical Zoan-type Shikigami, Great Swordsman, God Valley Era!]

Char Aznable travels to the world of One Piece and becomes the strongest general in the Kingdom of Vokawa, with a subordinate named Kaido.

When he and Kaido were being escorted to Mary Geoise, the Dark-Dark Fruit came to them, and a shrine was born within his body.

From then on, all Zoan-type Devil Fruits could be subdued and turned into shikigami for battle.

The game even gives you the strongest shikigami, Demon Void, right at the start!

Furthermore, there are special exclusive rewards for taming mythical beasts!

Subduing the vampire form rewards [Grafting], subduing the Yamata no Orochi form rewards [Chimera], subduing the horse bone rewards [Nest of Bones], subduing Nika rewards [Bungee Gum]... As the number of mythical beast shikigami increases and the chimera methods become more varied, Char discovers that he is invincible!

Kaido: "Mr. Machoro, teach me!"

Mo Xu Luo: "Nika Nika~~~~~"

The God Valley battle begins, and Char claps his hands together: "Chimera Dark Garden! Countless Shikigami unleash their power!"

Rocks: "This era is called the Black Emperor!"

When Char led his shikigami to attack Mary Geoise, ten thousand phantom beast shikigami slammed into his face, and Im panicked completely!

Transmigrating to the ninja world, I awaken a strategy and development system, but as my strength grows, why does it feel increasingly chilly behind my back?

"You're saying I'm special, right?"

"Senior, you gave me hope to live. I will never let you leave again."

"Chenye-kun, let's leave Konoha and go back to the life we ​​had back then, okay?"

Chen Ye: Speak properly, put the knife down first...

[Lighthearted, Semi-Invincible, Multiple Female Leads] For the sake of sales targets, the dump truck had to smash Link into countless parts and send them to various worlds. Having transmigrated to countless worlds, Link has no system, no powerful backer, and can only rely on the shared strength of his countless selves. Naruto World: Kaguya Otsutsuki pulls Link to her side, "Come, Black Zetsu, this is your stepfather." Hogwarts World: Wizards surround Link as the Third Dark Lord. Looking at the Elder Wand shoved into his hand, Link laments, "I never wanted to be Minister of Magic! You've ruined me!" One Piece World: In an interview with the news bird, Link humbly states, "I don't actually have Emperor-level combat power; the three I defeated were just civilian generals." Marvel World: Link: "How can I borrow power from dimensions...?"

Good news, I was killed by a train at home.

Even better news: he's become the navigator of the train.

Even better news is that you can travel to the world of anime by train.

What pioneering and interesting things did you do after becoming a navigator?

Zhang Huaichu stumbled into Kasukabe with a small food stall, starting by randomly selling dorayaki and takoyaki on the street. Unexpectedly, he gained loyal customers, including the Crayon Shin-chan family. He connected with a mysterious system, unlocking supply chains and expanding his privileges by accumulating positive customer reviews. His food stall became a city-wide sensation, evolving from a mobile cart to a chain store, and then to a global brand, ultimately achieving financial freedom.

While his career soars, he attracts the attention of beautiful women like the gentle Ms. Ageo and the capable Ms. Matsuzaka, leading to a dual pursuit of food and romance. Zhang Huaichu manages his business with one hand, making eel rice and yakitori snacks bestsellers, opening stores in hundreds of cities and thousands of locations; with the other hand, he pursues love, writing his own entrepreneurial legend in the heart of Kasukabe.

She was transported to the Fairy Tail world, but at an inopportune time—a hundred years too early. In this era… Mavis was still a six-year-old girl; Yuri, Precht, and Warlord were treasure hunters; Acnologia lived in seclusion deep in the mountains; Irene, heavily pregnant, hid in the forest awaiting redemption; Eleveselia's mission to 'exterminate the Six Divine Dragons' was still unfinished; Zeref had hastily built an empire in the Western Continent and roamed the world; Athena appeared in the Northern Continent, shocking the magical world; the Black and White Magic Orders rose up in various corners of the world; an unknown scientist began researching a magical artifact called the 'Dragon Slayer Crystal' using dragon hearts; the demon-based guild 'Tartars' lurked in the shadows; the Magic Council, eager for talent, devised a series of plans to counterbalance the rampaging mages…

Vongola transmigrates to the world of One Piece, becoming a member of the Beasts Pirates. He decides to stay on Onigashima and strive to become the fourth-ranked member of the Beasts Pirates. Although the members of the Beasts Pirates are skilled at all sorts of antics—the "Artistic Disaster" loves clubbing, the "Face Disaster" is all about abstract art, and the "Foolish Disaster" relies on the Ship King—it's common knowledge that Kaido is definitely the best teacher in the One Piece world. He quickly mastered Ryuo, Hakimasu, and Enchanted Sakura. "You're the worst class I've ever taught!" Fortunately, Vongola starts by fusing with the legendary Pokémon Tyranitar, becoming the embodiment of the will of the earth. What's so great about being the Pirate King? My idol is the Mountain Bandit King, Higuma!! I'm going to be the Mountain Bandit King! When Akainu's magma is shattered by the Dark Pulse, and Aokiji's Ice Age melts away under the Primal Force, the whole world finally feels the fear of being dominated by the Desert Tyrant! Kaido: I am the strongest creature! What is that 10,000-meter-tall Emerald Beast?!

There was no system for the time travel, and just when Xiao Nai was in despair, he got his own plug-in, Umbrella Brother's glory knowledge and technology, as well as the effective operating hand speed and corresponding nerve reaction speed that could achieve more than 800 APM.

So Xiao Nai followed the principle that a sniper who can't throw grenades is not a good sharpshooter and embarked on a professional career.

Xiao Nai's opponent commented on Xiao Nai like this: You never know what he can pull out from behind.

Ye Xiu: He really missed an old friend of mine...

Zhou Zekai said: Very strong, unfathomable.

Qiao Jingjing: I agree with this, but he detected mine.

[Livestream Exposed + Edited Video + Rocks Pirates + God Valley Incident!]

Seeing the shift in public opinion about Rocks online, and the iconic scene of him with a blue dragon on the left and a white beard on the right, the amateur content creator Li Fei was amused by the online comments and immediately uploaded a self-made One Piece review and commentary video.

Upon completion of the upload, along with the video, Li Fei's video was surprisingly posted at the very beginning of the God Valley War!

"What would Rocks' expression be if he knew his son had personally killed his best friend?"

Rocks: "That wretched sewer rat, daring to impersonate my son!"

"What would the young dragon think if he saw himself forming a revolutionary army, rebelling against the world, and saving two babies—one becoming a world-renowned Yonko, and the other a high-ranking priest?

"My hair?" Looking at the child in his arms, the dragon fell into deep thought!

"If Kaido saw himself treated like a model of filial piety and witnessed the arrival of 'Joy Boy,' would he suddenly realize his mistake?"

Kaido: "Six hundred and sixty-six, are you not even going to put on an act?!"

"If young middle-aged women saw their future figures and appearances, wouldn't they scream in terror?"

Lingling: "Get out of here! Am I that wrinkled old woman? I'll kill myself right here!"

"If the young Garp could foresee that he would later adopt Roger's son and be powerless to do anything about it, how would he feel?"

Garp: "Hahahaha, Roger, Whitebeard, I'm your father!"

Roger: "?"

Whitebeard: "??"

Bad News: Waking up in a different world. Good News: It's Prince of Tennis. Bad News: The protagonist was a tennis novice before the time travel. Good News: He met Jujiro, a demon who hadn't yet joined the U17 team. Furthermore, he awakened the mysterious Six Paths Dimension, where opponents he'd previously played against can appear in his dreams. Furthermore, each door in the Six Paths Dimension grants him a special ability bonus. After witnessing the rise of demons and facing off against the young "First Army," the protagonist joins Seigaku, completely overhauls the tennis club, and leads it to the national championship. He lays low in the U17 team, hones his skills in the expedition team, and rises to fame in the World Cup. Ultimately, he becomes the tennis king everyone dreams of! The synopsis is too much to read, but after the transition period, the excitement begins with the Jr. Tournament section.
