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.

Lin Luo traveled through the world of Souman and became Rias's childhood sweetheart.

He even changed his job to become an original magician, and as long as he had knowledge, he would continue to become stronger.

He even made a contract with the devil in another world, extended his claws into the heavens and the worlds, and recruited devil followers.

......

Rias: Only Lin Luo is my fiancé.

Kasumigaoka Utaha: Master, I want to replenish my magic again.

Asia: As long as I can help Brother Lin Luo, anything is fine.

Akame: Master, do you want to eat meat?

......

Unknowingly, Lin Luo can kill gods.

Shiraishi traveled to the world of soongan, where there are characters such as Yukinoshita Yukino, Yotsuya Miko, Eriri, Shinomiya Kaguya, etc., and also awakened the career panel. He attended classes and studied hard, awakened the "student" career, and his grades improved by leaps and bounds. By participating in the school's home economics and cooking class, he can unlock the "chef" career. ... Each career can make Shiraishi grow stronger by gaining experience. He met the transfer student Yotsuya Miko and unlocked the extraordinary career "Forced Exorcist"! Encountered Bloody Mary at the beginning. As a forced exorcist in Lisha, facing Bloody Mary (female imp loli), he had to use special means to force exorcism... Later, he even joined the dimensional chat room and began to evolve extraordinary. Entering the world of Suqing, he started the career of "Grand Mage" and killed gods in the world of God Slayer, starting a new career "God Slayer"... Unknowingly, Shiraishi has become a multi-level existence, overwhelming the heavens and all worlds.

Luo Guang traveled to a holographic world that blends the worldviews of DXD, Jujutsu Kaisen, Dark Rally, and Ghoul.

After his body became smaller, he didn't awaken his cheat code until he was twelve years old. As long as he practiced, he could continue to become stronger, and he was also given a portal function.

Of course, as a time traveler, he naturally couldn't be without a novice gift package. He started with the demon-slaying holy sword Esther, which could kill enemies and warm the bed.

Soon, Luo Guang became stronger, but he didn't go bald.

Baoyue Night Snack: "...Even if all the graduates were gathered together, they would not be his match."

Rias: "Rias, Rias, how can you be so stupid."

Shichito Sona: "Listen to me, thank you..."

Esther: "I was here first!"

What should I do if I travel to a world of anime mixed with hentai?

Good news, I am a devil!

As long as I sign a contract with a cute girl and make her my dependent, I can gain various special abilities.

Since I am in hentai, pleasure is the truth.

Lin Mu's eyes immediately fell on the high-quality dependent candidates, and accidentally took down the little angel Shiina Mahiru at the beginning!

Shiina Mahiru: "Since you touched me, you must be responsible!"

Kirisu Mafuyu: I am your teacher, are you serious? Shut up!

Shiina Mashiro: Hey, do you want to turn pornographic?

Akizuki Airi: Asshole, I don't like you!

Akizuki Marina: This is not right, don't...

Kujo Arisa: I really didn't curse you in Russian, please let me go!

Yukinoshita Yukino: "Scumbag, having a sister is not enough, how long are you going to bully people?"

On the way to contracting a dependent, how can Lin Mu achieve a harmonious dependent back garden?

Dragon Ball (Trial Mission Completed) School of the Dead (Complete) Guilty Crown (Complete) Slash! Scarlet Eyes (Complete) Dragon Clan (Complete) Heavenly Nine Songs (Complete) Battle Through the Sands (In Progress)

(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."

Ling Qing travels to the world of Zongman.

Good news: It is the world of Zongman's daily life.

Bad news: This daily life is not daily, there are angels, demons and dragons!

Good news: Awaken the two-dimensional trading chat skirt and become the owner of the skirt!

I, Ling Qing, am the owner of the chat skirt.

Here, you can trade with the owner of the skirt for any wish.

Fulilian: "Teach me how to quickly eliminate the demons."

Mecha-Machina: "Can Mecha-Machina really have hearts?"

Misaka Mikoto: "Can you save my sisters?"

Sakurajima Mai: "I want to know how to be seen again?"

Thor: "I have a sword of God stuck in my body, help me pull it out!"

Okay, okay, all you heroines want to trade with me, but...

Ling Qing: The trade is not about what you have, but what I want.

Ability? Possession? Right to use the body? There must be one I want!

Taimanin? Female knight? Female elf? Female succubus? And many big-breasted sisters?

The system always gives him some not-so-serious things.

Wait...

Not only big sisters, I also want lolita!

Then with these, let's build a crystal palace in the anime world!

The so-called Garden of Eden is just like this, right?

Mu Xiaoxiao has always believed that the three-piece set - hypnosis, time stop and drug - is completely overkill for the heroine of this world.

Because you don't have to be so troublesome at all, just drag it to a place where there is no one, and if you oppress it a little bit, they will obediently surrender, at most they will shout a few words, but their bodies are very honest.

There may be exceptions, at this time you can use threats to basically get 99% of women.

But that's not to say that the three-piece set is useless, on the contrary, these abilities are used against your peers.

So how do you survive in the world of Riban?

Gaining strength is a must, otherwise...... The world is hell for you.

"In order to survive, why can't you be a villain? "

Of course, it would be better if there was a strong second brother......
