As a master who traveled through time, Ian was not so familiar with Chaldea.

But it didn't matter, he had a special ability that other masters didn't have - that was the simulator.

This allowed him to leave his own footprints in history.

- Although it was not normal.

[You became the husband of the demon concubine, but at the same time you cheated on the Holy Knight King disguised as a man, and Britain was in a mess because of you. ]

[You controlled Tamamonomae, and as a master, you let Minamoto no Raikou witness what physical demon exorcism was. The ghosts of the Heian era avoided you. ]

[You made Medusa lose her mind, and the whole of Greece echoed her statement that she would take off her blindfold when she met you again. ]

[You are Jeanne's soul mate, and only you know how to make this saint who is usually very restrained achieve liberation and relaxation in various senses. ]

Ian had to say that this simulator that understands people's hearts is really suitable for him.

Solve all problems in his favorite way.

Everything is fine.

Until one day, when they came to him as servants.

Ian realized that he had caused a lot of romantic debts.

Takamine Haruto transmigrated into a crossover anime world. His childhood friend is Eriri, his deskmate is Yukinoshita, the school beauty next door is Kaguya, and his new neighbor is Gabriel.

He originally thought he could enjoy a peaceful life in this slice-of-life anime setting!

But then—he stepped outside and found the Female Titan, Annie.

Around the corner, he ran into the gluttonous Kamishiro Rize.

A concrete statue that twists people's necks the moment they look away?

A shy entity that hunts you to the ends of the earth if you make eye contact?

An immortal lizard that adapts to any environment and continuously evolves?

Takamine Haruto was overwhelmed.

To maintain his peaceful daily life, he established the SCP Foundation to contain anomalies from across the multiverse!

A full-family work.

Yanagi Nagao traveled to the world of sozoku (mainly the otherworld), obtained the blessing of the loan system, and became the head of the Takayanagi family.

Akizuki Airi: Why is it that the one who paid off the debt of Xier is not me, but my mother? I can do it too!

Takayanagi Kaoru: Should I call you big brother or dad?

Adachi Rika: Uncle, I also belong to you as an idol.

Oki Rinka: If you kill her, I can offer my mother

Katsura Kotonoha, Saionji Sekai, Amemiya Misako, etc. to conquer by myself!

Tatsumi has been reincarnated as "Chikusou" and has become the Dungeon Lord of Orario! His own dungeon connects to all realms! Highschool of the Dead, Shokugeki no Soma, Gourmet Prisoner, That Time I Got Reincarnated as a Slime, Undead King, Reincarnation: Jobless, One Punch Man, Little Garden... and every battle in the dungeon converts into experience points for Tatsumi! So... Ace Wallenstein: My two minutes of deep training... and Tatsumi-sama raised his level by fifty?! Busujima Saeko: My sword is Tatsumi-sama's sword, and my body is its scabbard! Nakiri Erina: No, why are the ingredients fighting here? Storm Dragon Veldora: Dungeon? What the hell are you doing here!? Black Dragon: Master?! Save me! Albedo: Please let me fight for Tatsumi-sama! Roxy: One magic spell raised Tatsumi's level by a hundred! What the hell is a 100x entry?! Start by entering the dungeon, conquer the heavens and the worlds, and build the supreme kingdom of God!

Quit the band and become a star god?!

Baili, who had traveled to the world of Zongman, decided to create a few Destiny Envoys with the help of the system.

However, the 'Starry Sky Train' that the system had snatched away kept receiving 'signals' from another world.

then--

Chaos Expansion: Clear the maze in the world of "Di Mistake"!

Chaos Destruction: Rias from "High School" becomes a Commander!

Chaos Harmony: Form a band for life, and then crush and destroy creation!

When the fate of chaos flows through planes such as "Hokei", "God Slayer", "Black Bullet", and "Azur Lane", everyone feels the glance of God!

Baili has only one explanation for his fate: what's yours is mine, and what's mine is still mine!

[Option 1: Become King] [Option 2: Become the Protagonist of a Light Novel] [Option 3: Become the Blue-Eyes White Dragon] Looking at these three options, a true time traveler wouldn't hesitate at all. Is there even a need to choose? The chance to be human is there in every lifetime... but the chance to become a Blue-Eyes White Dragon might only come once in a lifetime! ...That day, Artoria, following the villagers up the mountain to quarry stone, could never have imagined that the white stone she brought down from the mountain would actually contain a blue-and-white baby dragon. "Awoo—" "Great, so cute." "Can I keep it?" ...PS: Author's sensitive mind warning.

I traveled to the Pokémon world, which was a little different from what I imagined, but not too different.

I accidentally obtained a unique Poké Ball, which can not only capture Pokémon, but also capture... From then on, I was no longer single for thousands of years.

Lu Sheng, who obtained the template of Ash, was not only taken in by the kind-hearted Hanako, but also learned Pokémon battles from her.

Not only Hanako was conquered, but also the heroines and beautiful female gym leaders in the Pokémon world were conquered, and from then on they were no longer single.

And the Master of Free Life, who will be reset to zero in the new region? Will he be a runner-up in the regional competition?

All impossible.

Why not release it? Because later I found that there was something wrong with the captured Pokémon!

What the hell are you still a trainer?

You must be a trainer, and you can try another way to 'train' them!

And if you 'train' them in another way, there will be special rewards!

Transmigrating into the world of the "Hakoniwa" (Little Garden) in the world of crossover anime, Izayoi Sakamaki, while waiting for her invitation to the Little Garden, was invited to the Multiverse Chat Group and became its strongest member. Esdeath: "Izayoi, I will definitely not let you leave me too far behind!" Rikka Takanashi: "My contractor, following the ancient oath..." Nagatsuki: "You are hundreds of times stronger than the True Ancestor!!!" Touhou Project: "Um... Boss, do you have any extra Third Star Particles? Can I borrow some?" Gilgamesh: "I, the King, declare you the strongest!" Brunhilde: "Lord Izayoi, please save humanity!" Izayoi Sakamaki: "Thanks for the invitation, just arrived in the Little Garden, challenging the Celestial Theory." With her absolute power, Izayoi Sakamaki also became the chat group's sole administrator...

"We have discovered one of the oldest families." "Yes." "This family has been around since the beginning of the world. Its members from ancient times to the present include Anastasia, the last princess of the Tsarist Empire, Joan of Arc, the protector of France, the two talented women of the Heian period, Murasaki Shikibu and Sei Shonagon, and the British witch Morgan le Fay..." "Yes--!?" "In addition, we have discovered something." "This family has a humanoid treasure that has been passed down to this day-each generation will enter into a marriage relationship with these 'members'." "???"... People in Type-Moon get the family simulation period and can trace back to the past to add bricks and tiles to their own 'bloodline'. But in the end. I found out...I have become the ancestor of this family?

After crossing into the anime multiverse, the hidden world opened and monsters ran rampant. Just as Tsukikawa Shuu was about to embrace his slacker destiny, he discovered his golden finger was... marriage and offspring?

"I, Tsukikawa Shuu, despise the scourge of impotent protagonists! I categorically reject the toxic trope of 'flirting without commitment'!"

...

Gotou Hitori: "Eh? I'm... married? Well... I was never good at saying no anyway..."

Kitagawa Marin: "Marriage? Haha, sure... Wait! You're actually serious?!"

Fujiwara Chika: "I-It's not like I had a choice! But don't let the student council find out about this!"

Yukinoshita Yukino: "You want my hand? First take down that ridiculous 'Wanted: Wives' advertisement!"
