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.

Cheng Mo's life fell into despair.

My younger sister is seriously ill and her studies are on the verge of collapse...

Until he picked up a mysterious compass, his life took an outrageous turn——

Save Nezuko, accept Tanjiro as his apprentice, and get involved in the dispute between the Demon Slayer Corps and Muzan...

"Wait, didn't you agree to just be a profiteer?"

"My Lord, let's discuss business. I'll sell you penicillin, and you'll teach me breathing techniques, how about that?"

"Ms. Tamayo, I have a report on modern genetics. Would you mind using some of my blood to study it?"

"Muzan? Oh, don't run away with that moving gift bag of time and space coins!"

Cheng Mo just wants to resell resources and make enough money to save his sister.

When he looked back, he discovered that he had already held the authority of countless worlds and became the largest behind-the-scenes supplier in the heavens!

Tanjiro: "Teacher, what is the 'currency' of this world?"

Cheng Mo: "It depends. Maybe it's a devil fruit, maybe it's chakra, maybe... the future of a world."

(This book is also known as: "I Resell Supplies in the Heavens" and "After Accepting Tanjiro, I Became the MVP of the Demon Slayer Corps")

Crocodile: Boss, did you have to make such a cool entrance?!

He traveled into a book and became a villain, stealing the protagonist's wife at the very beginning.

Jiang Chen was very panicked. What should he do if he was going to be killed by the protagonist in a day?

Fortunately, the infinite identity system is activated, with a new identity every day, and identities can be stacked.

Day 1: Became the son of the chairman of Jiangtian Group.

The next day: Became a close friend of the president of Renli Bank

Day 3: Becoming the Shura God of War, a Feared God of War

Day 4: I became the Provincial Chief Justice

Day 5: Becoming one of the four legendary instructors of the Destiny Killer Organization?

Day 6: Became the founder of a space-based organization, the Great Emperor Wuji.

What’s exaggerated is that every ten identities can be synthesized once to become an even more exaggerated identity.

Transmigrating to the world of anime, the system rewards a complete set of Devil Fruits. First, recruiting a small helper made of binchotan charcoal. Then, looking at the familiar anime heroines from his past life, Xia Tian says he just wants a sweet everyday life. Yukinoshita Yukino, Yui, Miyazono Kaoru, and why is there also Mrs. Fueguchi Ryoko, Touka, and Miko? Whether you're ghouls, monsters, or evil spirits, if you don't let me live my normal life, I'll destroy you all with a thunderclap. Setting up a random stall, how could it have ended up in Beika Street, Yahara, and the pitch-black Tokyo? Natsume Reiko, a loli blinded by the enterovirus, is a warm and caring person. Xia Tian respects the fate of others, but will intervene when he sees someone unhappy.
