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!"

Mahouka (Temporary Absence) - Black Bullet - Return to Mahouka (In Progress) -

Volume 1: The Beginning of Mahouka

Volume 2: Black Bullet

Volume 3: Return to Mahouka

Lin Yuan traveled through the world of Zongman, awakened the system, plundered the entries, and became a hybrid of a hero and a demon.

Many years later, he awakened the demon bloodline, was driven out of the hero village, and wandered to the town of Kouou, where there are many talented people.

At the beginning, he killed Issei Hyoudou, plundered the gauntlet of the Red Dragon Emperor, took in a capable sister, and obtained the master-servant contract magic.

He opened the gate of the world and shuttled through the worlds.

Renalei: "Everything of the master is everything of mine~"

Naruse Mio: "Perverted brother, kill you a hundred times!"

Yotsuya Miko: "Can you really resist the cursed spirits if you eat this?"

Eriri: "Why is my mother here too!"

That day, the breath of the whale blew away the fog, and a new era arrived.

Chen Qi accidentally traveled to the steampunk apocalyptic game world "New Day", and started with a monster-level talent [Deep Sea Affinity]. The ancient deep-sea monsters under the sea regarded him as a kind.

However, although he had the talent of a monster, as a traveler, he still maintained the original intention of mankind, worked hard to upgrade, and was bound to become a world-famous monster hunter.

Finally, with his unremitting efforts, the most popular White Dove Times commented sharply:

"The evil blood from the ancient deep sea, the bastard who threatened the witch with tentacles, the fifth emperor alone, and the arrogant man who intended to conquer the Witch Sea!"

False news, naked false news!

Although he has tentacles, threatens witches, raises sea dragons, collects tolls, and sings a death chorus with the sirens.

But he is not the blood of an ancient god, but a good hunter who is dedicated to his duties.

Chen Qi cut off the fleet in front of him with a knife and seriously refuted the rumor.

[The unknown diary of a white devil]

"In 1991, I entered school, and together with the savior Harry Potter, the magic world gave me a good feeling. Magic is really wonderful.

"In 1992, I was a little bored today, so I just went out and killed a few Death Eaters for fun."

"In 1993, Dumbledore is really old and confused. How can people feel at ease if he doesn't hold power in his own hands? No wonder he is always disgusted by the people in the Ministry of Magic."

"In 1994, why is Voldemort so timid? He has been resurrected for a long time but there is no movement. Is he still the dark devil who doesn't take all wizards seriously?"

"In 1995, why did Grindelwald come out? Two generations of dark devils joined forces? Do you still have shame?"

"In 1996, he finally stopped hiding? Just right, solved it all at once. ”

......

Hermione: Harry! You must tell Dumbledore about this - well, you can tell Damon too.

Harry: Damon, thank you, you are the only one who always believes in me - what? You want to take a photo of me in women's clothing and send it to Snape - but - why?

Professor McGonagall: It is a loss for the entire British wizarding world that you don't participate in Quidditch!

Dumbledore: Damon, I think you are right, I made a mistake - I forgot the feelings of young people - but fortunately you are here, it seems that I can be a teacher with peace of mind, after all, this is the best for me.

Death Eater: Do you think Damon White has become more and more cruel recently? I really regret being infected with the Dark Mark...

After picking up a phone on the streets, Feng Yuchen was sent to the world of High School of the Dead. He, along with 100 people, have to travel through various worlds, fight and solve quests in order to survive.

Whoever dies in that world, would be teleported back to the real world without memories of what happened before and die in an accident one year later.

I was reborn into the Dragon Ball world and became Son Goku. I'm so happy that someone as socially awkward as me could be the protagonist! As Goku, my duty is to protect Earth when I grow up. Although I don't have the original Goku's childlike innocence, I at least have a much greater understanding of him and a clear grasp of the world's future. With enough effort, I also have the potential to save the Earth. As for women, they'll only hinder my training speed. So, I diligently trained day after day with Grandpa Gohan. Ten years passed in the blink of an eye, and Bulma arrived, taking me on an adventure. I just wanted to train hard every day, improving a little bit each day. However, what I feared most came to pass. After I grew up, because I wasn't married, Bulma, Chi-Chi, Launch, and later Android 18 all coveted me for a long time, all vying to marry me...

Traveling through Marvel, I woke up to find Mystique next to me and was being oppressed and exploited.

Lin En was panicked, but luckily the god-level system was activated in time!

[Ding! Detected that the host has completed a deep communication with the high-energy lifeform 'Mystique'...]

[The strongest auxiliary system 'Yin Yang Happy Buddha Body' is successfully bound! ]

[Congratulations to the host! Riven Darkholm's overall strength has been permanently increased by x1.5! Her luck has been permanently increased by x1.2!]

[Congratulations to the host! Your overall strength has been permanently increased by x1.1!]

[Congratulations to the host! Based on the target strength coefficient, you will receive a US dollar reward of $10,000!]

Looking at the system prompts and the extra numbers in the bank account, Lin Ente suddenly realized!

What kind of superhero, what kind of overlord of the universe, can it be as good as making the little sister stronger and making money for herself?

When Mystique killed Sabretooth in one move, shocking the entire Brotherhood, the look she gave Lynnte completely changed!

When Linnte accidentally came into contact with the out-of-control Scarlet Witch and tens of millions of dollars were instantly deposited into his account, Magneto directly regarded him as the hope of mutants!

[Ding! Strengthen Scarlet Witch, reward $1,000,000!]

[Ding! Strengthen Black Widow, reward $50,000!]

[Ding! Strengthen 'Goddess Sif' and receive a reward of $10,000,000!]

[Ding! Strengthening 'Goddess of Death Hela'... Reward amount? ? ?]

Years later, when Thanos arrived on Earth and found himself facing a "Legion of Girlfriends" who had been strengthened by Lynn to surpass the Infinity Stones, he was completely stunned.

"Don't come over here!!"

He traveled across the Douluo Continent and was assassinated because he accidentally heard Yu Xiaogang say that his theory was plagiarized.

At the critical moment, Wuhun awakened for the second time and escaped the disaster.

The Scarecrow's martial soul awakened for the second time, and even awakened his second martial soul.

From then on, he began a life of controlling souls and becoming a devil.

Yu Xiaogang, just be a good boy and become an evil soul master!

Tang San is your disciple, right? Now he has become an evil soul master that everyone wants to kill.

As the devil’s son incarnated from the Spirit Hall, I am the biggest villain!

Death is just a relief, but I want you to live a life worse than death!

After traveling through the world of Demon High School and wandering around in it for a thousand years, when Chen Eliog became the fifth demon king of the underworld, he received an invitation from a dimensional chat girl.

Out of boredom, Chen Eliog chose [Accept].

Cang Yue: Welcome newcomer! I am the strongest fighter among all the girls, let me know!

Esdeath: The person above is talking nonsense! I am the strongest fighter among all the girls, let me know!

Yukinoshita Yukino: Hello newcomer! As an ordinary person, I am trembling between two big guys!

Shinomiya Kaguya: +1!

"…………"

Chen Eliog: "Thank you for the invitation! I am in hell and have just become a demon king: I have official business to attend to, so I will hide for the time being."

Reborn in the Dou Qi Continent, he actually became Xiao Li and even awakened the "Many Children, Many Blessings" system!

There's no way around it; as a transmigrator, I can't very well refuse the system, can I?

...

Xiao Yu: "I will only love Xiao Li in this lifetime."

Xiao Xun'er: "Brother Xiao Li, don't you want to take responsibility for me?"

Little Fairy Doctor: "He is the only light in my life."

Yun Yun: "You little rascal, you just want to bully me!"

Queen Medusa: "I have never submitted to anyone, you are the first."

...

Years later, Xiao Li stormed the Soul Clan, his spear pointed directly at the Soul Emperor.

"Is it you who spread rumors everywhere, saying that my Xiao clan has declined?"
