[Based primarily on the Harry Potter movies, with some FGO elements added] [The author received guidance from Rowling; this is not random writing or based on assumptions, so please read with confidence!]

[The main character will not become the Saber King; there will only be a few chapters where he/she becomes a girl for fun. I couldn't think of a better name at the time, so I just used this one. The name will be changed after the book reaches 200,000 words. If you mind this, please don't read on. I'm very sorry!]

When Lynn was reborn into 20th-century London, he thought he was living the life of a protagonist in a rebirth novel.

But tell me, what the hell is magic in this world?!

As Lynn gradually accepts everything and prepares to enroll at Hogwarts to learn magic and fight Voldemort.

Tell me what the hell a magic circuit is!

Fate is here, right?! Does that mean we'll have a Holy Grail War next?

Screw the Type-Moon universe, I'm quitting, I'm giving up!

Because of an accident, Tang Zijun traveled to a parallel world.

Traveling with him was an unknown Kamen Rider Belt.

After realizing that there was a strange inner world called the Mirror Plane hidden beneath this world, Tang Zijun spent several years alone to successfully eliminate all the monsters in the Mirror Plane.

At the same time, he is gradually adapting to his new identity.

Just when he was living the peaceful life he wished for, Tang Zijun accidentally discovered his sister's secret - she was actually a magical girl!

Could it be that there is a faction in this world that even he doesn't know about?

Are there more evil monsters than just one in the Mirror Plane?

Was I going to have to watch my sister live the same dangerous life I had before?

Regarding this...

A most mysterious organization has emerged on the mainland – "Akatsuki".

No one knows who its leader is; all that is known is that its members are all monsters.

The runaway prince is being hunted down by the Tsukuyomi ninja "Uchiha Itachi";

An impregnable fortress was reduced to ruins by the art demolition expert "Deidara";

The ruler of the deep sea was slain by the tailless tailed beast, Kisame!

As for me, Ye Chen, the creator of "Akatsuki," I simply watched calmly from behind the scenes as my reputation soared.

"My chess pieces are now scattered throughout the world."

Transmigrating to the world of Bleach, he became Kyoraku Shunsui's nephew, Kyoraku Tokimura, and was bound to a check-in system—getting stronger by checking in—and even obtaining a unique time-type Zanpakuto. Time reversal, time stop, timelines severed… However, in the perilous world of Bleach, for his own safety, he decisively chose to join the Fourth Division. You say I'm lusting after Hana-nee's body? You bastard, I just want to develop better in the Bleach world! Wait, it's actually pretty good…

After Wen Yao arrived in the Hell of Gensokyo, Shiki-sama's daily life became like this: In a singularity, discussing the meaning of death with Ereshkigal, the goddess of the underworld; Izanami, the goddess of the underworld, confiding in someone about her loneliness in a broken world; exploring souls and the abyss with Ash (primarily Gensokyo)... Primarily Gensokyo, interspersed with other worlds, the narrative will likely not follow the above pattern. A mix of first and second settings, the setting is not rigorous (updates will be irregular for now; daily updates will resume after the previous main story is completed; I will try to maintain uninterrupted updates during holidays). PS: If Shiki fans can't find any Shiki-sama fanfiction, they'll have to write their own. PS: I'm bad at creating summaries; this is not the final version.

Bai Ming transmigrated, but his body was gone, and his life was hanging by a thread. Fortunately, he had a cheat code: he could transform into a character from the Collapsed Iron Legion to cause trouble and prolong his life. No choice, to survive, he had to put on a show! So he became the Great Black Tower, making the Black Tower Space Station stand up and perform a spinning routine. He became Ruan Mei, conjuring a giant of light, triggering a universe-wide emergency response, and causing setbacks for the Legion and the Company at every turn. As a Firefly, he ignited the Star Sea and kicked the starship of the Abundant People to pieces. Then he became Huang Quan, annihilating the Abundant Envoy Shu Hu with a single strike. As a Robin, he copied songs from his past life online. Then he became Silver Wolf, frantically boosting his online traffic. Until the victim realized something was wrong… Great Black Tower: Interesting, someone is impersonating me? Don't let me catch you, you'll be in big trouble! Ruan Mei: What a clever idea, I really want to study this other me. Firefly: Are there other Grammer Knights in this world?! I must find her. Huang Quan: Is there really someone so similar to me…? Do you still remember those past events? ...As the number of victims increased, Bai Ming, who was contemplating how to go into hiding, suddenly looked at Aha, who had brought all the 'enemies' there, and fell silent. "What the hell, Aha!! You tricked me?!"

Wu Qing accidentally transmigrated to a bizarrely ordinary world of crossover anime and awakened a skill point system.

From then on, he received random enhancement points every day, gradually embarking on the path to becoming an omniscient and omnipotent god.

Takanashi Touka: Would you like to eat my cooking every day, Kiriharu-kun?

Chitanda Eru: Kiriharu-kun, I'm curious about what kind of girl you like!

Yukino Yukinoshita: What is the real thing? Please tell me!

Tianyu Zhanzhan: Wuqing is only fit for the strong. If you disagree, come and fight!

Kasumigaoka Utaha: ...

This world is like a sieve, with things falling from anime, novels, and games every day. At first, it was just items falling, but then monsters started falling into this world, and everything changed. The barriers between dimensions seemed to vanish in that instant, and an apocalyptic catastrophe descended. [World Administrator's Log] [January 2nd: Found a portal; distance is no longer an obstacle.] [March 15th: Found a branch from the world's tree, along with a Goddess of Wisdom. I planted her in my backyard; she can keep me entertained.] [May 17th: Found a Heroic Spirit; she is the Queen of Britain, and she has a huge appetite—she can eat ten people in one meal.] [June 23rd: Found another Heroic Spirit; she is a saint from France.] [Found another person today, and it's a post-apocalyptic girl...]
