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.

Haruto completed the Ghost Swordsman training with great difficulty and went to Fujiki Mountain to participate in the selection. Suddenly, a line of comments passed by his eyes: Such a handsome guy, it's a pity that he will die in the next second.

A moment later, he was killed by the hand ghost hiding in Tengxi Mountain, who pierced his heart.

Coming to Fujixi Mountain again, Haruto, who thought he was dreaming, saw another line of comments before his eyes: The guy is very strong, but it's a pity that he can't save Santu.

Xuantu? Who is that?

I'm just an amateur demon slayer swordsman who has been practicing for two and a half years. Don't pin your hopes of saving people on me!

This book is also known as "Although I haven't watched Demon Slayer, I have been spoiled by the barrage", "I only have one frame of the original painting, and I rely on the barrage to argue with Muzan", and "What is the official complaining tool?"

Key points: There is only one female protagonist, the female protagonist is tolerant, no important plot characters are killed, and the official pairing is not broken up.

Contents: barrage comments + the protagonist's rich inner thoughts, which is more humorous.

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.

"? Bai'e beats Wuzhan? Doesn't having hands do that?"

"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."...

Muzan Kibutsuji: "It's useless. Unless I wait until the sun rises, I can be resurrected even if only a piece of flesh is left..."

"I am"

"?"

"The blazing sun will eventually rise!"

When Yasui Ryosuke is transported to the world of Demon Slayer, he is devastated.

Good news: He is familiar with the original work and knows the plot.

Bad news: The original owner was a sickly person who was not long for life, and the only cheat was the double-dealing system that required spending a lot of time and effort to become stronger!

"You mean killing demons grants you lifespan, which can then be used to enhance your breathing technique and sword skills?"

Yes, that's right~

How much longer can I live?

[Congenital liver failure, at most one year, haha~]

"Fuck your sister!"

Yasui Ryojie was angry.

What kind of good system would make a cancer-stricken host risk their life?

Knowing the original plot, Ryosuke would never willingly seek his own death by joining the scoundrel Muzan.

If that's the case, then kill!

Kill them until the sky darkens...

Ever since the Breathing of Fire was developed during the Warring States Period, more than 80% of the Flame Pillars have carried the name of Purgatory.

Even Rengoku Kyojuro, the last Flame Pillar of the Taisho period, gave up his own dawn for the dawn of others.

But if history diverges,

That one,

It keeps growing upwards,

The flower called "Purgatory"

Inadvertently, a fruit was born, but it was helplessly abandoned. Who can guarantee that it will sprout again as a seed in the shade and grow in a deformed form...

Or will it just be a fallen petal, transforming into nutrients to dedicate itself to the growth of future generations...

Su Chen traveled through Demon Slayer's Spider Mountain and almost got killed as he landed.

At the critical moment, he awakens the golden finger and has an incredible understanding.

In the end, he was injured and rescued by Shinobu Kocho and became a member of the "Butterfly House".

Su Chen goes out with Shinobu Kocho to rescue people during the day, and secretly kills ghosts at night to make money to support the girls in the Butterfly House.

While walking, constantly use the golden finger to observe and learn.

[You observed Shinobu Kocho's healing process and gained something from it. You created your own skill: Supreme Poisonous Healing!]

[You observed Kanao's sword training and suddenly an idea struck you, revealing a unique sword technique. A thought blossomed!]

You spied on the former Sound Pillar's thunder cry, gathering mosquitoes into thunder. Deeply impressed, you modified it slightly and developed the Lightning Release - Chidori Style!

From then on, Butterfly House had a famous and evil male doctor.

When everyone asked Su Chen why he worked so hard, Su Chen's thoughts were very simple.

"Why kill ghosts? Of course, it's to keep the flowers in the Butterfly House working well and feeding them!"

He was unexpectedly transported into his mother's womb and in the future, he became the twin brother of Gojo Satoru in Jujutsu Kaisen.

The two brothers, who both have six eyes, went down completely different paths in life from the very beginning.

Relying on his innate six eyes, he will eventually advance the Ten Shadows Technique to the Two-Element Shadow Technique.

The Demon Void adapts infinitely to all things, while the Jadoro perfectly reproduces all things.

Just because you can kill someone temporarily doesn't mean you can kill them forever!

Not winning now doesn't mean you can't win forever!

The future, wielding the strongest spear and the strongest shield, will dominate the world of magic with invincibility!

...

Lufa: Where's my armor?

Future: Here you go!

Su Nuo: I admit, you are stronger now.

The future: Don't forget, you are the challenger!

Lu Suo: In the future, I want you to be my devoted subject!

Future: Lu Suo, I will make you a dead soul beneath my halberd!

...

To you two thousand years from now: What's the use of guarding an empty throne? Come and protect me, stand up!

...

Note before viewing: Satoru and Shoko are a couple, as are Jaden and Riko. The rest are all male protagonists. The male protagonist has a strong villainous personality. If you don't like villainous characters or prefer Shoko as the female protagonist, please be cautious before entering.

At a comic convention, Otonashi unexpectedly encountered an adorable little octopus preaching, but made a sarcastic remark, and then found himself transported to the Naruto world.

Not only does it lack a system and bloodline, but it also has something resembling an octopus's mouthparts on its body...

The good news is that this thing can eat anything!

Whether it's animals, plants, or various elements, you can extract energy from anything you eat, and it can even strengthen your body and evolve your life level.

The bad news is that this thing replenishes what you eat...

Are the Sharingan and Byakugan strong? You'll grow as many as you eat!

Are tailed beast chakra strong? Then you probably wouldn't mind having a few more tails, right?

Are Devil Fruits powerful? Would it be okay to have more markings on my body?

In order to survive better, Otonashi has no choice but to forge ahead on an indescribable path of distortion.

Otonashi: "Don't let my usual respectable appearance fool you, actually I..."
