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!"

My name is Ye Xiao, of course you can also call me Abel Astaroth, an ordinary time traveler, and now a pure-blooded demon.

His eldest brother is Beelzebub, one of the four great devils.

Sona is his fiancée and Rias is his childhood sweetheart.

After awakening the memory and activating the system, I found that there is more than just the Devil High School in this world.

Like cursed spirits, evil spirits, monsters, disobedient gods, etc.

However, this does not prevent him from having followers.

Ye Xing travels through the world of anime and manga, a standard protagonist template, both parents are dead, and there is only one person in the household registration book.

Just when he thought he could live a peaceful daily life, he found that there are evil spirits in this seemingly abnormal world?

And there is a girl named Yotsuya Miko among his classmates?

Bad news, the dangers in the daily world are becoming more and more.

Good news, he himself is not a normal person.

Evil spirits and ghosts?

I started to get angry!

The exorcist of the abstract holy body, go!

[There will be Kengan in the future (but without Baki, the painting style is too weird, and the fighting power is outrageous), Kengan is also a plot adjustment, the main line is still against the supernatural weirdness, Death Note is a character appearance, but there will be no Death Note, the subsequent plot will be integrated with anime, Nura: Oni, Sanka Reiya, The Ancient Magus' Bride, Steins; Gate, Weathering With You, Your Name, Summer Returns, I can only think of so many for now, all of which are based on supernatural weird phenomena]

[The style is more abstract and funny, but when it's time to be serious, the male protagonist will also be handsome. ]

(There are multiple female protagonists, and their personalities will try to be consistent with the original settings. I won’t just pick them up without thinking, but I will pick them up if I like them.)

(Before each world begins, everyone's opinions will be collected. So please leave a message in advance about which heroines you would like to include and we will try our best to arrange it.)

(The introduction is weak, I don’t understand operations, and I can’t grasp the key points. I was fooled by my friends to start a book, and I can only write and write.)

Traveling through the heavens and the worlds just to fulfill the original dream.

Shen Lang: "I just want to have a family, what's wrong with that?"

Busujima Saeko: “Hehe”

Yui: “Hehe”

Esdeath: “Hehe”

Eri: “Hehe”

Yan Lingji: “Hehe”

Cai Lin: “Hehe”

No. 18: “Hehe”

Holy Kesha: "Hehe"

Bibi Dong: “Hehe”

Willow God: “Hehe”

…

"I'm just a passerby, speaking my mind, I think what Shen Lang said is correct."

Kitahara Ixia, who traveled to the daily world of souman, has an all-powerful plug-in!

After he became omnipotent, one heroine after another appeared beside him.

Sawamura Eriri: "Ixia, please teach me how to draw comics!"

Kasumigaoka Utaha: "How can I write a novel as delicate as yours!"

Furuhashi Fumino: "Lord Ixia, please teach me, this useless person!

Inuisa Suzuha: "I want to wear the cosplay clothes that Ixia made for me all the time!"

Akiyama Mio: "I want to form a band with Ixia!"

... "Then it depends on your sincerity!"

Kitahara Ixia said.

Travel to a world that is a fusion of science and comics.

It is also connected to the Devil Convenience Store, which sells Devil Cards and can draw out various treasures!

So, Chen Mo went crazy killing here!

Chen Mo: If the price you pay is enough, I can consider letting you draw one more card.

Kisaki Eri: Can learning sophistry make my tongue more flexible?

Mao Lilan: You and my mother actually have that kind of relationship?

Suzuki Sonoko: As long as you don’t limit the sales, I am willing to give you all the money and even the person!

Vermouth: Don’t talk, come in!

Yukiko Kudo: I'll let you touch the black stockings, can you let me draw one more?

Haibara Ai: Will my transformation really increase your combat power?

.........

Looking at the acquaintances lining up one after another to draw devil cards, Chen Mo fell into deep thought. Who should I make pay a price that will satisfy me today?

I have obtained the legacy of a mysterious multiverse-level civilization, and can travel to countless anime worlds.

So what to do next? For passion and excitement? To meet beautiful girls? To save the world from doomsday? Or fight for all that is good? Or is it about establishing a super organization that spans countless worlds? What are you thinking? Only children make choices. As an adult, of course I want them all. Take them all!

After traveling to the world of anime, Hikage Miyauchi obtained a magical diary. As long as he wrote in it every day, he would get rewards.

But he had read diary online before traveling, and he knew that what he wrote would most likely be seen by the heroines of this world.

As a salted fish with no ambition, Hikage Miyauchi immediately decided to be a pure fun person in this world.

"What era is it? Who still writes traditional diaries?"

"No one is really willing to write their true feelings in a diary and then be watched by countless heroines, right?"

"My mother told me that this world is very dangerous. Boys must protect their privacy when they go out, so don't think about coming to me. After all, I am a man you will never get."

As Hikage Miyauchi continued to write in his diary, an "Avengers Alliance" composed of heroines who could see Hikage Miyauchi's diary was quietly born.

They gathered together for only one purpose, that is, to find the owner of this diary and ravage him inhumanely!

As the first reincarnation, Mo Yan not only survives in an endless world but also creates an eternal kingdom. With a fate system fused into his body, he gathers lovers, allies, and powers from countless dimensions.

[Ding! It is detected that the reincarnation A/A1 is the first reincarnation, and preferential treatment is given. 】

[Policy 1: Since the reincarnation space is newly created and there are no optional worlds, the authorized reincarnation A/A1 can choose the time of descent before entering the mission world. ]

[Policy 2: In order to encourage Reincarnator A/A1 to incorporate various worlds into the Reincarnation Space, Reincarnator A/A1 is given eternal life and the ability to freely adjust his appearance and age. When Reincarnator A/A1's points are negative, no penalty will be given.]

[Policy 3: When the world incorporated by the Samsara Space reaches the minimum requirements for the complete opening of the Samsara Space, the Samsara A/A1 can formulate the Samsara Space's policies for other Samsara within the scope of authority.]

[Policy 4: When giving reincarnation A/A1 to enter the mission copy, they can choose the camp at will, and it will not cause the camp mission of the previous camp to fail. ]

【Note: The preferential policy is only available to reincarnation A/A1. 】

It was not until Moyan was selected by the reincarnation space and passed through that a trace of energy overflowed from the chaotic turbulence between the worlds, which activated the system.

After traveling through time and reincarnation as a demon, he also has a master who claims to be a superior demon, Rias, who often attacks him at night;

Himejima Akeno, who is also a servant, always wants to reproduce with him;

In order to avoid physical exhaustion and to survive, he works hard to improve his strength.

In order to live a peaceful daily life with his harem, Long Yi, as a demon, said that he still needs to work hard, either to be "invincible" in the world, or to have no "enemy" in the world.
