Official Introduction: Now approaching you is: Muzan's nightmare, the destroyer of the Twelve Demon Moons, the head of the Infinity Castle demolition office, the most righteous person in the Demon Slayer Corps, Sabito's savior, the eternal absentee of Kanae Kocho's tea party, Giyu's good senior brother, the founder of Fist Breathing, and a grandmaster.

Willow branches provide shade, that's it!

Kanae Kocho: "I invited him to a tea party ninety-seven times, and he refused ninety-seven times. He's so gentle."

Shinobu Kocho: "Why should I be trained by iron fists? It's infuriating, sister!"

Akaza: "A powerful person, the best in physical combat."

Muzan Kibutsuji: "A monster who destroyed all my Demon Moons with his bare hands and blasted the Infinity Castle to pieces, you call him human?!"

Unofficial synopsis: Yagyu In transmigrates to the world of Demon Slayer, but the system believes he is in the world of One Piece and identifies him as a Marine.

You can earn Navy Points and rewards by doing things that are in line with the Navy's rules.

Yagyu In: No, buddy, is this right? Where did this pirate from the Demon Slayer world come from that I need to catch?!

Pirates are attacking! Strike immediately to capture or kill them!

Looking at the man-eating ghost before him, Liu Shengyin realized that the system had gone mad.

From then on, the Demon Slayer Corps had one more instructor who liked to smash people's heads with his iron fist of love.

This book is also known as "Left Fist's Overpowering Entanglement Deals High Damage, Right Fist's Overpowering Entanglement Deals High Damage," "Three Punches Shatter Evil Spirits, Sir, I'm Just an Ordinary Person," "Overpowering Aura is Also Qi, and Qi is Breathing Technique!" and "Muzan, Are You Hiding Well? The Marine Admiral is Coming to Get You~"

Note: This book is a crossover anime/manga series, and will later explore other worlds.

Ghosts and monsters in the darkness spy on the human world.

In unseen corners, bloodshed and cruelty quietly grow. Ghosts eat men, men slay ghosts—millennial legends and grudges are intertwined with fate...

When Tanjiro Kamado stepped into Nada Spider Mountain, a huge screen appeared in the sky.

The question-and-answer system has officially started. As long as you answer the questions, you can get various rewards, including but not limited to "resurrection", "turning back into a human", "blue red spider lily", etc., to solve your unsatisfactory wishes!

After resurrecting his wife, Akaza said: "I am Fist Pillar. Muzan, I will *your Sage!"

Shinobu Kocho: "I have a gentle personality? Wait until I get the reward and you will know what a killing angel is [sinister smile]."

Agatsuma Zenitsu: "Grandpa was forced to commit suicide? I'll show you what a fucking thunder pillar is! What a fucking thunder pillar is!"

Douma: "The punishment is to experience extreme pain? There's such a good thing?!"

Mitsuri Kanroji: "Eh?! Mr. Iguro likes me? Then I'll confess right now!!!"

Kokushibo: "I want to resurrect Yunichi. Even if Muzan comes, he can't stop me. I said it!"; Muzan: "You are really my living father."

Tomioka Giyu: "I want to be the most popular person [cold face]."

Muzan Kibutsuji: "The reward is a blue Higanbana?! As long as I can get it, I'll do anything~"

......

Is the plot difficult to accept?

Through questions and answers, all of them were changed to perfect endings!

(cp: After chapter 20, I will not promote the official version, only Komare and Snakereen)

Si Jinkun, who traveled to the Demon Slayer world, shouted at the beginning: I don’t want to be a human being anymore!

He went completely crazy after arriving in the world of Demon Slayer

That shadow that has lingered for a thousand years—Muzan Kibutsuji! That pitiful creature who cowers in fear because of the curse, that false king who vainly seeks immortality!

All his struggles and blood ghost arts became futile jokes in front of Si Jinkun's ultimate body that combined the curse of the stone ghost face and the essence of countless ghosts!

He treats Wuzan as a high-end bun

It also forced the demons and the Demon Slayer Corps to join forces for the only time in a hundred years.

Many years later, Si Jinkun, who had already become a JO-level creature, looked at the world he had ruined and fell into deep thought.

Since he regained consciousness, Yang Quan has been staying in a dilapidated house. Having lost his memory, he didn't know where to go, so he stayed here.

One day

A butterfly-like girl suddenly appeared in the soft moonlight, and Yangquan learned from her that he had become a ghost.

The girl had a gentle smile on her face, but it didn't show in her eyes. She said she wanted to get along well with the ghost, but she stabbed Yangquan with her light knife.

What Yang Quan never expected was that in the near future, a girl named Shinobu Kocho would hold his face and look at him straight.

"Mr. Yangquan, please stay with me forever!"

..........

It was not until a long time later that Yangquan heard his own answer.

"good"

[Rating just came out!! It will gradually rise!!]

[Pure villain + pure evil + cannibalism + invincible + no system]

Kurokawa, a sickly man coughing up blood every day, has been surrounded by malice since birth because of the twisted lines on his back. His only sister, who loved him, was burned to death by the villagers while protecting him.

In his deathbed despair, Muzan, lurking in the shadows, offered him a way out.

The demon blood enters the throat, awakening the seven aspects of the Blood Demon Art.

Pride, envy, wrath, sloth, greed, gluttony, lust

This filthy world is disgusting!

I will judge your crimes!

Having unexpectedly transmigrated to the world of Bleach, Suoh Tsukasa was still imagining what the future held for him. Unfortunately, this thought only lasted until his stomach growled. He was hungry. As he plucked bitter leaves and stuffed them into his stomach, his only concern was how to solve the problem of sustenance…

Kotoji Mirai transmigrated to Soul Society and became a carefree, lazy bum in the 9th Division. Unfortunately, his salary wasn't enough for drinking, so he resorted to writing novels for the *Seireitei Newsletter* to earn extra money. His first novel, *The Arrogance and Loneliness of a Prodigy*, featured the protagonist "Aikawa." The next day, a junior named Aizen Sosuke, with a gentle smile, came to ask him about the profound meaning of the "Throne of the Sky." His second novel, *The Murderer of Meteor City*, featured the protagonist "Shuka." That night, the gentlest captain of the 4th Division, Unohana, sat in his room with a sword, smiling as she asked him: "What is the meaning of 'the loneliness of a mad beauty'?" Kotoji Mirai was now panicking, currently writing *The Invisible Empire Hidden in Soul Society*. Would he end up killing off his own people? Kotoji Mirai discovered that, without realizing it, he had acquired the title of "The Most Beautiful Nobleman in Soul Society." "Isn't this going to kill me?" He drew his Zanpakuto, unleashing his true name, "Zhuiwen Banshou" (meaning "All Things Under Heaven"). "The future of Soul Society will be written by me."

[I will be joining V on June 18th, I hope everyone can continue to support me! ] Seeing that the world was on the verge of breaking, the world consciousness that was unwilling to dissipate cooperated with Dazai who held the book. They summoned souls from higher dimensions, and as long as they collected the energy that overflowed during their activities, they could use it to repair the world. In the higher dimensions, a holographic game called "Dazai's Cross-Time and Space Help" was born. A miracle among billions of worlds, Mr. Dazai is holding a book and planning a brilliant plan to usurp the throne. Now the future leader is seriously short of people, and needs several enthusiastic people to rush to Yokohama and Dazai.
