What if Aizen Sōsuke descended into the world of Naruto?

An Ran finds himself in the Ninja World playing the role of the mastermind Aizen. To fully unlock his character's potential, he joins the Akatsuki under the name Aizen Sõsuke. Just as he begins his infiltration, a mysterious invitation pops up:

You've been invited to the Dimensional Chat Group.

And that's when chaos begins.

Dimensional Chat Log:

The Actor: Hey guys, I'm Aizen. Just joined.

Newbie here.

Konan: Welcome! Funny timing - Obito brought in a new recruit too.

Gintoki: Wait, a new recruit? Isn't Itachi supposed to join in like... two years?

Konan: Not Itachi. He says he's Aizen Sosuke. Claims his strongest illusion is Kyōka Suigetsu. Then he pulls out a sword like he's some kind of samurai. Totally bizarre, right?

Gintoki: ???

Sawamura Spencer Eriri: ???

Xia Chen unexpectedly transmigrates to the world of One Piece, activating the story island check-in system right from the start.

"What? You get stronger just by clearing story islands? Doesn't that mean you're about to take off?"

Upon visiting the first island, Windmill Village, I obtained the Zoan-type Mythical Beast Fruit, the Great Sage Equal to Heaven form!

Is Nika the Sun God really that powerful?

Do you know that even if you become a god, you're just one of the 100,000 heavenly soldiers and generals who can stop me?

He then happens to meet Luffy, who is just about to set sail, and at Luffy's invitation, becomes the vice-captain of the Straw Hat crew.

Join the main characters as they explore story islands and grow stronger!

...

The synopsis is insufficient; please proceed to the main text, which primarily focuses on the bond between the protagonist and the Straw Hat crew members.

Jiang Chen traveled through time accidentally and began his journey in anime.

The world is tentatively determined to be: Naruto - Attack on Titan - Demon Slayer - Sword Art Online - Detective Conan, etc.

————

In the Naruto world, Jiang Chen obtained a system that gives him a 10,000-fold return on his disciples. As long as he teaches his disciples, he can get corresponding high-fold return rewards.

As a reward, Jiang Chen taught Hinata the black coffin of the ghost way that he brought from the world of death.

During the Chunin Exam,

Neji: "Give up, Hinata, you are not fit to be a ninja."

Hinata: "I don't want to run away anymore, Neji-nii, let's have a showdown! A faintly turbid emblem reveals an unruly and arrogant talent...Hadō no 90: Black Coffin!!!"

Everyone: "She calls me brother, but she kills me. This girl is so scary!"

I traveled back to the day Konoha was founded and awakened a fancy sign-in system.

He signed in to Konoha Village as an ordinary person for fifty years.

It has everything: martial arts techniques, ninjutsu, bloodline limits, Demon Slayer breathing techniques, One Piece Haki, and more.

Due to his cultivation techniques, Thousand Hands Immortal has a long lifespan and grows younger with age, earning him the title of "Immortal Master" among the villagers.

The villagers didn't know until the night the Nine-Tailed Fox attacked the village and Thousand-Handed Immortal descended from the sky.

There is still an immortal god in Konoha!

At the same time, a cold, mechanical voice echoed in Thousand Hands Long Life's mind.

"Ding! Triggered the event check-in. Successfully checked in on the night of the Nine-Tailed Fox's attack on the village. Congratulations on obtaining: Multiverse Chat Group!"

Tony Stark joins the chat!

Portgas D. Ace has joined the chat!

Tanjiro Kamado joins the chat group!

Rorschach picked up a mobile phone with a "friendship system" installed. There was an online friend named "Tokisaki Kurumi" on the phone.

This online friend was an actor, and he played Kurumi very well.

Rorschach thought it was very funny, so he chatted with this severe chuunibyou patient.

It was fake anyway, so he spoke bluntly and often said a few flowery words.

Until one day, he received an invitation from Tokisaki Kurumi to meet.

Then... he traveled through time!

In the dirty alley, human remains fell on the corners, and the smell of blood irritated the nasal cavity.

Tokisaki Kurumi, who had just killed someone, appeared in front of Rorschach and looked at him with a smile...

(The wives I want to write about are Kurumi, Shinobu Oshino, Junji, Nezuko, Elle, Leticia... and so on)

Join the crew and witness the world of One Piece together with the Straw Hat Pirates.

Martial arts expert Lin Ning's soul transmigrates to an unfamiliar ocean world, becoming a young man from the East China Sea.

Relying on his martial arts will from his previous life, he awakened Conqueror's Haki upon waking.

He learned Conqueror's Haki Entanglement, encountered Luffy who had just set sail, and joined the Straw Hat Pirates.

He combined his past life's martial arts to create a body-forging method, and worked hard to improve alongside Luffy, Zoro, and others.

While cultivating their skills and exploring the truth of this world, they embark on unknown adventures with new companions.

As the sea breeze rises, their legendary journey begins!

[No system + multiple heroines + semi-invincible in the early stage + pure invincibility in the late stage]

(The heroine includes the fairy queen Erza, if you don’t like it, please don’t enter!)

Mo Bai travels through time and space to Fairy Tail, possessing amazing magical powers and eight Dragon Slayer Crystals. He encounters Makarov and joins Fairy Tail, thus beginning his adventure.

He annihilated the Dark Guild, single-handedly swept through Aedras, traversed the Eclipse Gate to annihilate Deliora and rescue Uru, overwhelmingly won the Grand Demon Tournament, and shone in various S-rank commissions...

Natsu: Hey, Mo Bai, come and compete with me! (Bang! He is knocked away by a punch)

Makarov: Looks like the guild will have a new S-class wizard with the youngest qualifications!

Acnologia: I sense the mighty power of a dragon from this person... Destroy the dragon! The dragon must be utterly destroyed!

Kazufu traveled to the Naruto world and became a member of the Uchiha clan.

Countless attempts to open the Mangekyō Sharingan failed, and the time had come less than a year after the night of the genocide.

In order to survive, he deduced several plans.

Defected from Konoha and joined Akatsuki.

He abandoned evil and turned to good, becoming close to Sarutobi Hiruzen.

Build a good relationship with Uchiha Itachi and establish a bond.

However, no matter which plan is chosen, the final result is a dead end.

In desperation, Hefeng complained to his ninja cat that there was no way to survive in this world.

However, he didn't expect that his own ninja cat would steal a thunder fruit for him.

Hefeng was completely confused.

But the more outrageous thing is yet to come...

Ninja Cat thinks your physical skills are too weak, so he stole the Navy's Six Styles Secret Manual overnight!

Ninja Cat thinks your mental strength is too weak, so he stole the golden bug arrows overnight!

Ninja Cat thought your swordsmanship was too weak, so he stole it overnight...

Hefeng: Lie down or push forward, this is a question worth thinking about!
