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.

My name is Sean, I come from Blue Star and traveled to the Panlong Universe;

The good news is that this is still not long after the creation of the world, and the main godhead has not yet descended, so there is a chance to become the supreme main god;

After countless efforts, I became the supreme ruler and achieved great perfection, but then the golden finger came~

"If I don't die today—" Paul's voice suddenly rose, each word seeming to be squeezed out from the center of an electromagnetic storm, carrying a metallic friction texture and overwhelming killing intent:

“From this day forward, I will broadcast the wails of the defeated through your communication networks! I will pave every naval base port with the wreckage of your proud warships! I will keep the gates of justice permanently short-circuited, and I will cause Marineford's power to go out inexplicably every night! I will become the longest and most lucid nightmare in your naval careers—”

The railblade was raised high above his head, aimed at Garp, Aokiji, and seemingly at the entire World Government.

"—Until all of you live in endless regret, regretting why you didn't kill me completely on the ice plains today!"

[The early stages are more slice-of-life, the mid-stages take place in the Star Iron world, the female protagonist is tentatively located in the Great Black Tomb, the protagonist will not stay in the Super God world for long, and will leave here, the next world is tentatively Star Iron]

For reasons unknown, Lin Xingchen transmigrated to a strange world.

The story begins on a desolate, unfamiliar planet, with a hideous demon chasing after him. Fortunately, the protagonist's key advantage remains.

But... something seems off about this newbie gift pack.

What is this thing?

Lin Xingchen stared at the purple body that was almost the size of a galaxy and fell into deep thought. Before he could think any further, the body that was originally the size of a galaxy turned into the size of a normal person in the blink of an eye.

Moreover, relying on her memory, Lin Xingchen could even vaguely make out...

After I transmigrated into the world of Detective Conan, the system turned me into a cat and then exploded.

From then on, the world of science fiction gained an incredible blue and white British Shorthair.

Conan: That dead cat is a master at taking candid photos. I don't know how many embarrassing moments of my life have been photographed by him.

Ran Mouri: Tom is amazing. I can understand what he means from his shouts.

Vodka: That dead cat was ridiculous. I clearly saw the bullet I fired riddle it with holes, and even when it crawled out of the pond, its body was leaking water like a showerhead, but in the blink of an eye, it was perfectly fine again.

Gin: When I pointed my little pistol at that dead cat, that dead cat pulled out a Gatling gun.

Kidd: I thought I was good enough at hang gliding, but that dead cat can turn a piece of wood into a cat-shaped hang glider.

...

This is the story of a cat with Tom Cat bloodlines wreaking havoc in the world of Detective Conan.
