Traveling through the world of Demon Slayer, Shigure opens the role-playing system of the universe.

The higher the missions completed and the degree of character restoration, the stronger the power gained.

The first task required at the beginning is Bai'e.

"Nanook... uh no, Muzan Kibutsuji, I bring destruction upon you!"

Muzan Kibutsuji: "No red blade? No markings? Are you also a pillar?"

Shigure: "Pillar?... Pillars are considered pillars."...

"I am"

"The blazing sun will eventually rise!"

She transmigrated into the Naruto world, only to become Sakura Haruno. After drifting aimlessly for five or six years, she finally realized she had no system, no cheat codes, and no special abilities—a complete "three-nothing" transmigrator. Was she destined to become a mere foil to Naruto and Sasuke, a laughingstock among the new Three Ninja? No! Who says a commoner can't rise to power? In the original story, she became a Kage-level ninja; as a transmigrator, she would only be stronger! Thus, determined, Sakura Haruno began her relentless pursuit. Ultimately, relying on her extraordinary genjutsu talent, she stood atop the ninja world.

Bai Ran, male, was originally just a gamer who stayed at home, slacked off, and loved playing "Azure Archives".

One day, while out buying desserts, I got nine rainbow cards in ten draws. I was so excited that I didn't notice the car coming from the side of the road. Before I could even see what was happening, I was hit by a truck and thrown more than ten meters away, instantly reincarnated... (Don't actually go looking for trucks to die.)

I woke up to find myself in Kivotos, and as a student...

Kitagawa, who transmigrated to the Naruto world, gained an equipment slot. By collecting equipment, he could acquire the unique properties associated with it. But why were all the equipment items somewhat strange? Kurenai Yuhi's Original Bandage: Jonin-level Genjutsu talent, a slight buzz is a feeling. Obito Uchiha's Alarm Clock: Always one second late, being love-struck is a disease. Kakashi's Mask Undershirt: Kage-level Lightning Release talent, a repressed flirt is your true nature.

Both Shi Qiu's time travels are extraordinary.

One became a member of the Uchiha clan in the Naruto world, and the other became a member of the Pirate King's crew in the One Piece world.

The Naruto world.

Uchiha Shikichi wanted to change this messed-up ninja world, and his first step was to seize power within the Uchiha clan and occupy Konoha...

One Piece world.

Shi Qiu is a true pirate who abides by the rules of the pirate world and pursues power, fame, and wealth.

From a crew member to a legendary pirate, he gradually grows stronger and more powerful, ultimately achieving his ambitions...

Yu Cheng transmigrated into the body of the young patriarch of the Whirlpool Clan. Faced with the impending extermination of his clan, he dared not stop for a moment!

Fortunately, his three adopted sons were transported to the worlds of One Piece, Demon Slayer, and Martial Soul, respectively.

And so—

"Old Cheng! Is the Dark-Dark Fruit any good? Hehe... I want to use the Impure World Reincarnation~"

"Come here! Old Cheng, I'm now an Imperial Beast. Which soul beast do you want as your summoning beast? I'll teleport you there!"

"Uchiha Madara wants to fight you? And the Otsutsuki want to join the fray?! Fine, let's fight!! Behold my Sun Breathing!!!"

Several years later.

Uzumaki Yu Cheng transformed into the Demon King, wielding the Supreme Great Sword, stepping on the Black Dragon Emperor, his Rinnegan lowered, looking down at the dying Allied Shinobi Forces.

This book is also known as "Naruto: My Unbeatable System" and "Naruto: My God-Level Choice System".

Chen transmigrates to the Naruto world and awakens a god-level choice system. He receives rewards for every choice he makes, and he also receives a month-end sign-in reward for every time he jumps to the "Chicken You're So Beautiful" game at the end of the month.

Dust: I'm really not a black-hearted person.

[Chicken, skilled in knife work]

[Chicken, gained 1% of the Ten-Tails' chakra share]

Dust: The path to invincibility begins here. From now on, infinite chakra will be at your fingertips.

The story begins with the genius of the Uchiha clan founding the "Night" organization. Stay tuned for the next installment!

He transmigrated to Konoha Village, becoming a cannon fodder genin. The Second Shinobi World War raged on, and Natsume's ninjutsu consisted only of the D-rank Three Body Technique and the C-rank Earth Release: Wall. His superiors were utterly inhumane, always using him as cannon fodder, forcing him to narrowly escape death on almost every mission. Natsume felt he could die at any moment. Fortunately, the "Good Boss System" activated. By sacrificing his direct superior or seizing their position, he could gain a chance to win rewards. Sacrificing a Chunin captain granted him the Kagura Mind's Eye. Sacrificing a Special Jonin captain granted him a Jonin-level chakra. ...When the death rate of Natsume's direct superiors became extremely high, he finally faced questioning from Konoha's higher-ups, "Natsume, we need you to explain why your superiors' casualty rate is so high?" "Because they deeply understood the Third Hokage's..."

[Bungo Stray Dogs fanfiction + short story + romance + OOC warning + immature writing style, free-flowing, slice-of-life plot, the protagonist will not be part of the original story, it's a fanfiction with many original characters, please don't read if you mind, and you can get the general style from the synopsis] Self-introduction: I am an assassin. After all, in a dangerous world overflowing with superpowers and guns, isn't it normal to be an assassin? By the way, my performance is 100%, and I still have the professional ethics of an assassin. I can't call myself the number one assassin, but I can barely be the number two? After all, my main job can't support my living expenses, so I can only occasionally do side jobs to maintain my precarious life. Serious synopsis: Me (without blushing or skipping a beat): "I'm a law-abiding citizen." "..." Would a normal person introduce themselves like that? After several years of assassin experience, I unexpectedly joined the Armed Detective Agency after a day trip to the military and police, becoming a member. It feels good, except my wallet hurts. Everyone: "Isn't this your own fault?" I can't refute it: I'm overwhelmed with sadness. Later, the conspiracy known as "The Book" fell on my head. I'm so annoyed: I've already told you I have nothing to do with the book, but you just won't believe me. Thumbs up, six. And then… I can't spoil any more!!! Attention!!! This isn't a fictional story; the main character is female. CP: Hmm, forget it, I'm too incompetent to write romance. (Originally it was Dazai.) Let's go with a friendship story. Also, proceed with caution before jumping in.

Good news: I've traveled through time, to the world of Fairy Tail. Even better news: The magic can summon plants, and not just any plants, but the ones from the Plants vs. Zombies mini-game. Bad news: I haven't seen Fairy Tail, so I don't know the plot. Even worse news: The summoned plants aren't the ones Kern is familiar with. ...Kern, having traveled through time, gazed upon the summoned [Worker Sunflower], [HR Ice Shooter], [Surplus Value Sun Mushroom], and all sorts of other bizarre plants, lost in thought.
