[Transmigrating to the Uchiha Clan] + [Conquering Konoha] + [Retrieving All Tailed Beasts] + [Conquering the Ninja World] + [Counterattacking the Otsutsuki Clan]

The protagonist, Qi Ren, transmigrates into the Uchiha clan...

Itachi: Qi Ren is the one who guided me on my love journey with Izumi...

Shisui: Even though I know you're not a good person, I just can't help but listen to you...

Fugaku: Qi Ren, if you let me become Hokage, I...I'll...I'll listen to you from now on...I'll listen to you...

Orochimaru: Interesting. Let me see the god you speak of!

Tsunade: Thank you, Saito-kun! I'll take the position of Medical Director!

Naruto: Hey hey hey... How did I get double Kamui?!

Sasuke: I will catch up with my brothers...

Danzo: Why should someone like me be allowed to live...?

A man from Qi: Even a roadside cat must contribute its value to me!

[Not joining a crew + beating Luffy + beating Garp + crippling the Marines + establishing his own power + multiple Devil Fruit abilities]

"Lenno, this is an order! Coby is the future hope of the Navy; he cannot be tainted!"

Karp looked at Reno meaningfully, "As his senior, let him take on this responsibility!"

Having said that, he left Leno alone in the dark Impel Down.

"I've been in the Navy for six years! And all the merits I've accumulated are less than what a guy did in two months?"

Leno's sense of justice was completely shattered. What kind of bullshit justice is that!

In his desperate and unwilling state, he awakened his superpower.

After leaving Impel Down, Reno rose through the ranks from Vice Admiral to Yonko (Four Emperors), then Pirate King, and finally became the ruler of the world.

Garp, watch closely!

How can the traitor you personally forced to rebel, now act as a pirate?

Crush your revered naval hopes into dust!

I want to become the grandson of the Pirate King, and I'll die right in front of you!

The justice he upheld his whole life was trampled underfoot!

[Fun Fiction + Worldview Clash + Harem] That year, thanks to two hundred episodes of "Approaching Science," Rosser became a famous exorcist in Shinjuku. Initially, he just wanted to easily earn 100 million yen, then go back to his hometown to get married and never come to Tokyo again to avoid being beaten to death by his victims. But when the evil spirits actually came, and he blew up the school building with his made-up spells, he realized, "So I'm a god?" Rosser grinned maniacally. "In this world of evil spirit crisis, your savior has arrived." First, he'd transform into the Abyss-Eyed White Dragon, giving the world a little dragon-related shock. Then, he'd shift the blame, create a high-spec Type-Moon game, connect it with FGO next door, and whoever loses becomes a Lostbelt. Add some subspace, Cthulhu, and fight fire with fire... Crossover characters: Stop! And so... Goetia: Your Beast Law is... wait, what the heck is the Law of Cycles? Gudako: Mashu, could it be that our world is the Lostbelt? Anime Crossover World: Please, please, switch back to the evil spirit! I don't want the Cthulhu dimension! Sakayanagi Arisu: He didn't treat me like a cripple, nor did he treat me like a human being. Kazuma & Ayanokoji: Commander Rosser is my faith, my loyalty! Yukinoshita: Brother-in-law, won't my sister be angry if you do this? Tokisaki Kurumi: You scumbag god, watch me exhaust you with my three thousand clones!

[Entire clan defection + Mangekyou Sharingan at the start + semi-invincible + destroy Konoha] [Sharingan + Devil Fruit] [System downplayed]

Upon opening his eyes, he found Shisui smiling in the afterlife, while he himself had transmigrated into the famous "filial son" Uchiha Itachi, awakening the Devil Fruit inheritance system.

If a member of the family eats a Devil Fruit, they can gain the same power!

The Will of Fire? Protect Konoha? Slaughter the entire clan?

What a joke! I am the son of the Uchiha clan leader, destined to revitalize the Uchiha clan!

First, lead the entire clan away from Konoha, seek development, challenge the Ninja War, and destroy Konoha!

"Naruto, you must build good relationships with the elites from various villages who came to the Chunin Exams this time. Later... what? You reported them for cheating on the exam??"

"Naruto, you absolutely must bring Tsunade back to the village! She's the granddaughter of a legendary figure, and one of the legendary Sannin... What? You brought her back to your house?!"

"Naruto, this Five Kage Summit is of utmost importance. You must remember not to act recklessly as before and antagonize other villages... What? You beat the other four Kage to their knees??"

"Naruto, now that you've become Hokage, your every word and action represents the village, so you must be careful with your words and deeds... What? You're demanding that all female ninjas come to your office every day to report on their work??"

...

Transmigrating into the Naruto world, becoming Naruto before the Chunin Exams, and awakening the Evil Deeds System:

You can gain evil points by doing evil.

Ninjutsu, Sage Art, Bloodline Limits—all are within easy reach!

Naruto in the original work—a loser, a simp, a master of talk-no-jutsu, and suffers all sorts of injustices...

Now--

"Heh, doing bad things and doing whatever I want, that's my way of the ninja!"

He transmigrated to the world of High School DxD and obtained a god-level achievement system. Just as he was considering how to achieve his goal, Orpheus suddenly spoke up. "Let's have a child together." [Ding, congratulations to the host for completing the seven-colored achievement, "Orpheus actively invites you to have a baby!"] [Congratulations to the host for obtaining the achievement reward: Kabbalah Tree!] The Kabbalah Tree, ten primordial elements, four worlds, twenty-two paths, three pillars! Crown, wisdom, understanding, compassion, strictness, beauty... a kingdom! Activity, formation, creation, outflow! "Divine Armor, tenth level! Spiritual reversal, tyrannical ruler!" "This ending, I will never accept, I will never allow! Let it flow into the entire universe, my tyranny, my reason! Let all things restart, eternal return!" "..." Orpheus looked completely innocent: "I just wanted to have a child to defeat the Great Red, why did it turn into..."

Our family has fallen on hard times.

The once glorious Uchiha clan has been reduced to its last remaining descendant, you.

[Side Quest 1: Enhance your strength and uncover the truth behind the family's decline.]

[Second Side Mission: Spread Your Fame Far and Wide, Do Something Great and Shake Up the Ninja World.]

[Side Mission Three: Propagation and Restoration of the Uchiha's Glory - It is Our Inescapable Duty.]

Looking at the system in front of him, Tiandao wanted to shout, "Damn idiot! System, do you even recognize me as an Uchiha?"

However, looking at the rewards listed by the system: [Sharingan, Hashirama Cells, Sage Mode, Yin-Yang Release.]

"Since that's the case, then let me see your limits. System, activate it!"

Tiandao, born a commoner, is a mere transmigrator. Watch as he stirs up the ninja world with the help of a mentally challenged system.

(Naruto, System, Multiple Female Leads)

Staying up all night to rank up, I suddenly died and was reborn as Naruto Uzumaki.

This Naruto world is a bit of a trap:

Ashura's chakra is gone, my inherited talent from my parents is ruined, and I've become an even more disliked, gloomy loser than in the original story?!

Fortunately, I was bound to the "Naruto Mobile Game System" when I transmigrated.

Completing system tasks will earn corresponding rewards, allowing you to upgrade your rank, break through level limitations, and increase eight key stats: Ninja, Body, Illusion, Sage, Power, Speed, and Refinement.

then--

"I heard that you, Uchiha Itachi, can form six hand seals in one second? Sorry, I can form forty-four hand seals in one second. Having fast hand speed means you can do whatever you want."

"The God of Shinobi, Hashirama Senju, has more chakra than the Tailed Beasts? Interesting. I'd like to call you second, because I'm number one."

When the Otsutsuki clan descended upon the ninja world, and stared into deep thought as I conjured the Exploding Star Rasenshuriken I had just formed, all I could say was:

"As expected, being a Hokage is not as good as being a 3,000-point Super Kage."

He was Minato Namikaze's classmate, but the class's quietest member. He had no particular skills, and his lazy chakra prevented him from learning any ninjutsu. If nothing unexpected happened, he would become cannon fodder on the battlefield.

But—he has a cheat code! His chakra increases by 0.5% every day, and now he has one-tenth of a chakra, so the future looks promising!

I'll just focus on wielding my sword; the rest is up to the chakra!

When the Ten-Tails was born, he carried an invincible chakra and slowly raised his sword—Do you also want to dance?

Under my chakra, all ninjutsu is just flashy nonsense.
