He traveled through a parallel modern world. He traveled through a prosperous ancient dynasty transformed by a time traveler. When he was inexplicably transported through time for the third time, the audience in the live broadcast room turned out to be everyone in both worlds? Knowing many unconventional and magical skills, he simply chose to ignore it.

My name is Yotsuba Mahiro, a time traveler.

Sent to the Demonic World by an alternate-world teleportation ambassador, I became a Adjustment-Type magician of the Yotsuba clan.

Besides being born with eyes capable of replicating all forms of magic and physical techniques, perhaps my greatest supporter is my cheap mother, Yotsuba Maya.

After fifteen years in the gloomy Fourth Research Institute, my cheap mother suddenly gave him a crucial task.

"Although you're a Adjustment-Type magician of the Fourth Research Institute, you're also my child."

"So, it's also your duty to produce a worthy heir to the Yotsuba family."

It's just about carrying on the family line, a simple matter. Is the bloodline of the Ten Master Clans and the Hundred Houses enough? What if

I add your sister Miya? What if

I add the lolita from the Black Bullet world?

What if I add the assassination group from the Zelda: The Sisterhood?

What if I add a singing diva from Guilty Crown?

...

After traveling through ten worlds, he asked Maya again.

"Is that enough now? If not, I can add more!"

"I fight Sukuna? Really?"

Fang Yi looked at Sukuna, the final boss of the Jujutsu Kaisen world, who was walking slowly towards him.

There is also the elimination mission issued in the first world of the reincarnation space.

[Fight with Sukuna Gosei and survive]

Eliminate after failure

I suddenly felt full of malice.

(Subsequent worlds, Kabutojo, Demon Slayer, re0, Kill Aka, One Piece, Type-Moon Fourth and Fifth Wars, Bleach, Naruto, etc.)

Multiple female leads, crossover anime, no eunuch ending, protagonists lacking any true goodness or beauty.

While traveling through various anime worlds, Tetsuya Amano unexpectedly discovers that all the female protagonists have a treasure chest with a progress of 0% above their heads, which triggers his obsessive-compulsive disorder!

The key to open the box was actually on the male protagonist.

To control them and their lives.

Tearing apart Aki Tomoya's dignity and publicly humiliating Hikigaya Hachiman.

When Aki Tomoya knelt at his feet, when he treated the Service Club like a playground...

[Starting with Everyday Life] [Saekano: How to Raise a Boring Girlfriend] [The Quintessential Quintuplets] [Mai-senpai] [Oregairu] [Various Anime Crossovers] [We Can't Learn This] [Hate My Sister Isn't Sora]

Ye Feng transmigrates to a world of anime and manga, starting out as a complete stranger in a completely poor place.

Fortunately, she gained the power of Command Seals, which can grant any wish that isn't too outrageous, and she even started a romantic relationship with Kasumigaoka Utaha.

From then on, Ye Feng began to interact with popular characters such as Eriri, Yukino Yukinoshita, and Mai Sakurajima.

Kasumigaoka Utaha: "Kaede-kun, please discuss inspiration for our novel with me!"

Yukino Yukinoshita: "Only Kaede-kun can melt my cold heart."

Mai Sakurajima: "I want more fragments of my memories so that others can see me again."

Nakano Miku: "Could you please come to my house as my tutor, Kaede-kun?"

Involved in: Mai-senpai, Oregairu, Saekano, The Quintessential Quintuplets, Kaguya-sama: Love Is War, Mafuyu Kirisu, etc.

Crossover anime, crossover anime, crossover anime!

Although it's a crossover anime, it's so crossover that even the author doesn't know how to describe it. All I can say is that the author will probably write about the characters you want to see in the future.

The story will begin with GBC as the main plot, and other anime plots will gradually be introduced, such as Oregairu, Lonely Rock, and Lost Children. There are also some other anime whose main plots have ended, but they will be continued in this novel.

Don't worry too much about the location and time. The protagonist isn't Superman; he can't fly from one place to another every day or travel through time.

Multiple female leads, and other anime male leads with gender swaps, so just obediently endure the protagonist's abuse along with the female leads.

There may be out-of-character (OOC) content; please do not read if you mind. Thank you.
