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!"

After traveling through time, Haramura Makoto always thought that he was nothing special.

Until that white-haired loli with devil horns and kimono appeared.

I actually traveled through time twice?

My ability is actually realm?

Why does the sun feel so warm?

"These are not very important, can you explain? Why are the leaders of these communities all girls, Makoto?" Shokuhou Misaki

The ongoing world of the anime - Academy City (returned many times) - The Heroic Tale of the Failed Knight (coming soon)

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!!"

This is a single-female-lead story, not a time-travel/invincible tale. Please stop bringing up the early camera thing! The protagonist isn't a time traveler! She's not that close to Misaka Mikoto at the beginning; that plot point will be resolved around chapter 170!

Accelerator: I am the strongest.

Touma Kamijou: Ever since the new neighbors moved in upstairs, I feel like there are more and more things happening around me.

Misaka Mikoto: I'll definitely beat him next time.

Shirai Kuroko: That guy who looks like a mountain, my dear older sister would never like him.

Teacher Xiaomeng: That child? He's really a headache.

Zero: I just want a peaceful campus life. I don't want to cause trouble, but trouble has come knocking on my door. Shouldn't I clean up this mess?
