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.

He woke up to find himself surrounded by an unparalleled beauty! Little did he know, Li Qing had transmigrated into the body of King Zhou, the last king of the Shang Dynasty! Faced with chaos, a rebellion in the Western Zhou, and the deification of the Three Sages, what to do? Don't panic, I have the Human Emperor System!

The rating is a bit low right now, that's normal. [System Flow] [Multiple Female Leads] Qian Yelan transmigrates to the Naruto world and obtains a daily settlement system. [Refining chakra for eight hours, gaining 0.01 chakra] [Throwing shuriken 500 times, gaining basic shuriken mastery] [Changing Kushina's kidnapping fate, gaining the Uzumaki physique] The story begins with a red-haired girl who has just transferred to the school walking up to him and asking, "Is anyone here?"

Sakuya transmigrated into the Naruto world and became a member of the Uchiha clan, a family wiped out by their own people! Luckily, he awakened a god-level daily login system, earning rewards simply by logging in every day! Day 1: Navy Six Powers! Day 2: Whitebeard character card! Day 3: Zanpakuto: Kyoka Suigetsu... And so, without realizing it, Sakuya became invincible! When the Third Hokage and Danzo planned to attack the Uchiha clan, Sakuya smiled and shattered the Hokage Rock with a single punch! Sakuya: "From today onwards, I stand in the heavens!" Minato Namikaze: "Sakuya's Flying Thunder God Technique is even better than mine, what am I called the Yellow Flash for?" Madara Uchiha: "In this ninja world, only Sakuya is worthy to dance with me!" Onoki: "His Susanoo is bigger than a mountain, no joke!" Kushina: "Sakuya! I want Gear Second Vibration Mode!"

Having traversed a dungeon, Evan arrived in Orario. He always felt that the dungeons he visited were somehow different from others. Corner attacks, mimics, and the classic three wolves and the Royal Archer duo—the sheer malice was unbearable. But it didn't matter. Evan: What doesn't kill me only makes me stronger!! And so, many years later… Black Dragon: Breaking the seal of Dragon Valley, he encountered Orario's number one fighter, whose stats were insanely high, a monster in strength, whom he couldn't defeat despite his best efforts. Damn it. Who raised this guy?! Dungeon: Yeah, who knows… (feeling guilty)

Levi, who arrived in Orario with a pay-to-win system, only wanted to do three things: make money, become stronger, and spend time with Hestia. As for heroes? Let whoever wants to be one be! He had no interest! But as his strength increased, the darker side of the DanMachi world began to emerge. And that wasn't even the worst part! Hephaestus: "Anotherworldly weapon? I'd better take a good look! Elbow, come inside with me!" Freya: "I was here first, Levi, you should look at Seele too!" Ishtar: "Be my godfather, and all the girls in the Pleasure Quarter will be yours." Aphrodite: "Freya and Ishtar both like you? Does that mean if I steal you away, I'll be the most powerful goddess of beauty?!" Artemis: "How dare you summon the Artemis Arrow without my permission?!" Demeter: "Levi, thank you for saving my child." Astraea: "Young man, I feel your justice~" Hestia: "You thieving cats, stay away from Levi, you bastards!!!!" ...ps: The goddesses liking the protagonist ≠ the protagonist liking the goddesses.

In Tokyo at the end of the century, the neon lights of Ginza flicker, the bars of Roppongi are awash in decadence, money flies everywhere, nightclub girls roam, and dark power lurks. In this materialistic and sinful Tokyo, a reborn villain, using the famous detective as his prey, begins his hunt to seize everything… [A heavily modified Japanese setting (Detective Conan timeline) + Conan + crossover anime + villain + not a dark and brutal storyline.]

[Pure pirate power system] [No system] [Multiple female protagonists]

[Darkness + Multiple Fruits] [Special Physique with a cheat-like ability, allowing physical attributes to grow to the level of a Mythical Beast Awakening] [As close to the original work as possible]

As a descendant of the David clan, Dawn originally only wanted to go to sea to figure out his physical condition first, and then work hard to become stronger and avenge his family.

However, he unexpectedly encountered the Dark Fruit that should have belonged to his own kind. As the old saying goes, if you don't take what Heaven gives you, you will suffer the consequences. So he decisively ate it.

"I'm sorry, Teach, you can't handle this fruit."

(PS: This book is a bit slow-paced, but the author will update frequently, though the first 100 chapters will be slower.)

[Multiple female leads: Albedo + others] + [No system] + [Written by real people] + [Harvesting faith]

What do you mean by "the kingdom has been conquered by the Sorcerer King"? Who is the Sorcerer King?

What do you mean the Holy Kingdom has converted to the Holy Domain God?! And who is He anyway?!

What do you mean the Dragon Kingdom now has a Dragon King who has ascended the throne?! And where did this Dragon King even come from?!

The Platinum Dragon King gritted his teeth as he looked at the continent in complete disarray: "Damn it, which group is the Dragon Emperor's filth?!"

"What do you mean they're all in cahoots!"

Years later, the Platinum Dragon King gritted his teeth as he watched the Magic King stand beside the Holy Lord, while the Dragon King, on whom he had placed his hopes, respectfully called him "Father."

Being strong is a temporary thing, but being handsome is a lifelong thing. The transmigrator named Vegapunk touched his big head and made up his mind to change his body and appearance first, and then think about other things!

However, there seemed to be a small problem during the soul transfer. The person was fine, but why was the world changed?

Alright, it seems that before returning to the pirate world, I need to first unify the ninja world and develop a world shuttle.
