Lord of Mysteries + Detective Conan + certain characters from other anime

The male protagonist has no romantic partner.

Lin Xiuming is just an identity; in reality, he is Morofushi Hiromitsu, who survived death but lost his memory, and went from being Shinichi Kudo's neighbor to becoming Conan's right-hand man.

I, Uchiha Hofu, accidentally traveled to the world of Naruto.

I obtained the Multiverse Sign-in System! And I got the SSR-level treasure, the [Herrscher of Reason Core]!

I single-handedly repelled the Iwagakure army!

I led my people to evacuate Konoha and establish our own clan!

I slaughtered the darkness of Konoha—Shimura Danzo!

While chatting and laughing with Ban Ye, we decided the fate of a great nation!

I witnessed the collapse descending upon the ninja world!

I defeated the strongest enemy I have ever encountered—the Herrscher of Water!

I am the current head of the Uchiha clan, the former daimyo of the Land of Water, the five-core herrscher of the Hokage, and the demon god of the end—Uchiha Hatake!

The Otsutsuki arrives in high spirits, only to be brutally beaten by an ordinary Uchiha Jonin. That would be quite a sight!

Thanks for the invitation. I am currently in the ninja world, just resurrected. I am now the divine son of the Evil God Cult, the chief spokesperson of the Evil God, and the number one lackey appointed by the Evil God.

Based on the principles of dedicating his life to fighting for the Evil God, the Evil God being supreme and omnipotent, the Divine Child Simu devised the [Sacrifice the Ninja World] plan.

Orochimaru: "Only by submitting to the evil god can I obtain eternal life."

Nagato: "True peace is achieved by sacrificing the entire ninja world. Without people, there will be no conflict."

Obito: "I want to create a world where only Jashin exists."

Deidara: "The Jashin-sama is the true art!"

Decades later, the evil god was resurrected and, looking at the Allied Shinobi Forces that came to punish him, slowly typed a question mark.

"I've been sealed away for hundreds of years, and now I'm the public enemy of the ninja world?"

[Slow-paced training + no female protagonist + Hunter x Hunter world adventure]

Zhao Tianming transmigrates into the world of Hunter x Hunter for the second time. Having already transmigrated into the world of One Piece, he awakens his Haki once again. In order to learn Nen, he takes the Hunter Exam, but unexpectedly gets entangled with Hisoka.

That said, Hisoka is actually a pretty good guy, except for his habit of being naked in front of me all the time...

P.S.: I really like Hunter x Hunter, so I got carried away and started writing this. But I only realized how troublesome Hunter x Hunter fanfiction is when I was halfway through. All the messy Nen abilities and world-building made my head spin.

She transmigrated into the Naruto world, only to become Sakura Haruno. After drifting aimlessly for five or six years, she finally realized she had no system, no cheat codes, and no special abilities—a complete "three-nothing" transmigrator. Was she destined to become a mere foil to Naruto and Sasuke, a laughingstock among the new Three Ninja? No! Who says a commoner can't rise to power? In the original story, she became a Kage-level ninja; as a transmigrator, she would only be stronger! Thus, determined, Sakura Haruno began her relentless pursuit. Ultimately, relying on her extraordinary genjutsu talent, she stood atop the ninja world.

Liu Xing transmigrated into the world of Food Wars! and opened a small restaurant outside the Totsuki Culinary Academy. This small restaurant not only lowered the prestige of Totsuki Culinary Academy but also constantly embarrassed the academy. However, Totsuki Culinary Academy was powerless to do anything about this small restaurant.

Xia Mu, who runs a Pokémon breeding center in the Donghuang region, lost his father, Xia Canghai, a near-Elite Four level Gym Leader, during a battle against a Pokémon invasion. Everyone believed the Xia family would decline and severed ties with Xia Mu. The Donghuang region Gym Qualification Inspector said, "Xia Mu, I regret what happened to your father, but this is my job; the gym must undergo an annual audit." The mayor of Shenshan City in the Donghuang region said, "Nephew, I apologize for your father's fate, but the rules cannot be broken!" Numerous Pokémon breeding center suppliers said, "Xia Mu, our business is small and our profits are meager. Starting this month, all payments must be settled on the spot." Shenshan Middle School said, "I'm sorry, after the school's evaluation, you do not meet the criteria for a 'Top Ten Pokémon Student.'" Just when everyone was turning against him, Xia Mu discovered that his local...

Having transmigrated to another world and been bound to the Red Alert system, Sherlock thought he was about to embark on an invincible and crushing life.

To his surprise, the moment the newbie quest popped up, he was shocked by the bizarre requirements—

[New Player Quest: Kiss a dragon within 24 hours and successfully borrow 100 units of gold from it]

"System, are you sure this is a commander's mission and not a suicide mission?!"

Even more outrageous, the soldiers he casually created started to complain wildly and had an invincible chatterbox attribute.

While others were still honing their magical skills, Sherlock led his Red Alert army, massing troops and pushing forward while simultaneously bickering with his own units—

"Commander, the Holy Mother just sent an alliance request. When should we go and destroy her?"

If fate is unfair, then expose it!

Reincarnated as a human, from infancy to top-tier magician, he will reclaim everything he lost in his previous life. In this life, he will personally tear apart the shackles of his past: first, he will become a fierce warrior who roams across other worlds, washing away past humiliations with his sword; then, he will ascend the throne of top-tier magician, making all those who dare to look down on him tremble under his magic.

He owed him fairness in his past life, and in this life he will take it back, bit by bit, with interest, using magic and power!

After passing through Kuroko's Basketball, Lin Ye became known throughout Teiko as the "basketball idiot".

Until that day, he touched Aomine Daiki's head...

[Ding! Touching Aomine Daiki has successfully copied his talent "Formless Shot"! Awakening level 30%!]

[Hot Forum Post] "The New Demon King of Imperial Light! Is Lin Ye, who pats everyone on the head, a model of etiquette or a gifted bandit?"

[Opponent Collapses] A national-level ace player, clutching his head, frantically swerved around the court: "Coach! He's coming! He smiled at me! Time out! My hairstyle can't be messed up!!!"

Aomine Daiki (crouching down with his head in his hands): "Don't touch me! Why is your 'no-holds-barred' style even more lewd than mine?!"

Murasakibara Atsushi (shrinking in a corner): "I was wrong, I'll never say you're weird again, please give me back my power..."

Midorima Shintaro (glasses shattered): "My absolute accuracy? No! Yours is a lock-on cheat! I'm reporting you!"

Ryota Kise (questioning his own existence): "It takes me five minutes to imitate him, but he copies me... in just one second? Who's the real genius at imitation here?!"

Seijuro Akashi (Emperor's Eye goes out of focus for the first time): "I can see into the future, but I can't see into you... Am I the next person to be copied?"

When everyone thought that replicating Qingfeng was Lin Ye's limit—

In the national competition finals, he gave a friendly smile to the talented exchange student from the United States.

"I heard your 'zone' is a unique talent?"

"Now, it's mine."
