Travelling to the world of the type moon, in order to have the power to protect himself, Novia chose to travel through history again and create his own legend.

"We believe in one, the Almighty Lord, the creator of all tangible and intangible things."

In the ancient Roman Empire, which had declined from the divine era, the church was united three hundred years in advance by itself.

"... The suffering, and stood up on the third day, ascending to heaven, will come, to judge the living and the dead, and the great judgement of the apocalypse will disappear because of the atonement we wait for.

Later, when it was learned that Behemos landed from Gaul, the branches flying over Athens, and the Leviathan, which set off a Mediterranean tsunami...

"No, the Judgement of the Apocalypse is really coming!"

Is it time for Zisha to go to heaven now?

.......

"Is Xiaokai also counted as Kai? I can't stand Kukulkan's slap in the past few lifetimes.

The Shadow of the Lord on the Earth, the Roman Emperor, the First Pope of the Church, the Holy One, the Rider of the Dragon of Albion, the Two Kings of the Huns, the Pioneer of Central and South America, the Master of the Silver Key, Novia, said frankly.

【You were born in a knight's family. 】

[You watched the fire burning for seven days and seven nights, and doubts began to arise in your heart for the first time. You felt that this was not right.]

You said, "You must know that my teachings are here."

[In the end, you carried everyone's love, and you became the only saint in Britain. ]

…………

You were born in a carpenter's family.

【You seem to be a little different. 】

【They began to call you Saint.】

[But you said: Dove, I will return your authority to you, and from now on there will be no distinction between man and God.]

…………

【You were born in a Christian family. 】

[You kind of hate those pagans, but you have to tolerate their existence. ]

【Your country was defeated.】

[You will protect everyone! ]

[Detective + FGO + Slice-of-Life; basically an otaku-style novel; beloved trope of Heroic Spirits falling in love; NOT a harem; Warning: MC’s presence is relatively low — if that bothers you, turn back!! Some Heroic Spirits’ genders follow historical records, and there will be CP pairings, e.g., Old Saber x Eriri, Oda Nobunaga x Miku Nakano. Personalities of Heroic Spirits are kept intact. If you can’t accept that, just… don’t read!]

Transmigrating into a world that’s a crossover of slice-of-life anime and Detective Conan, Aoki Makoto, with no knowledge of the plot, thought his life would be simple: rely on his phone from his past life, stay far away from trouble, focus on making money, and spend a rich but boring life.

Little did he expect that his real cheat would arrive… sixteen years late!

System: “Become a Master and save the world!”

Aoki Makoto: “Do I get a girlfriend?”

System: “…Huh?”

Aoki Makoto: “Why am I not interested in all those anime heroines? Because my ideal type is Gudako!”

System: “…Fine. If you succeed, I can help introduce you. But first, I have some bad news.”

Aoki Makoto: “In front of Gudako, nothing is a problem.”

System: “The detailed personality data of the Heroic Spirits has been lost, so you’ll have to play them yourself. In other words… have you read any ‘vest novels’*?”

Aoki Makoto: “…No problem, no problem. Oh, by the way, does your introduction come with a marriage guarantee?”

And so begins the story of wearing the “vest” of Heroic Spirits to save the world… while also, incidentally, falling in love.

The Type-Moon World is a unique parallel world.

In this world, there are Heroic Spirits, vampires, gods, and all kinds of supernatural beings.

There are conspiracies, schemes, factional struggles, and even the descent of Outer Gods!

There’s Saber’s Excalibur!

There’s Rider’s Bridle of Chivalry!

There’s Illya’s lively charm!

There’s Matou Sakura’s ultimate redemption!

There’s Tohsaka Rin’s tsundere pride!

There’s Medea’s transformation!

There’s Cú Chulainn’s Luck E!

There’s Sun Wukong, Wu Zetian, Qin Shi Huang, Shuten Dōji, Yu Meiren, and… so much more!

Reborn in the Sea of Life.

Ian, who was raised by Tiamat as his offspring, felt the extraordinary gravity.

Tiamat:

"It's dangerous outside."

"Especially girls."

"It's safest here in the Sea of Life."

Ian:

"Mother, the more you say that, the more I want to go out..."

"And--"

"I really can't drink the Sea of Life anymore."

After a long time.

Facing the numerous girlfriends from different eras around Ian.

Tiamat revealed his true form, circling and roaring in the sky.

"Kill all of you!"

"Take Ian away, bad woman!"

"He is my son!"

[You are the Master of Chaldea, the savior of humanity. ]

[Your evil deeds are known to everyone from Orleans to Camelot. ]

[Every singularity has left traces of being ravaged by you. ] [Your fierce reputation can make servants tremble in fear, and can also stop the little demon pillars from crying at night. ]

[And you like to use this sentence to encourage your comrades the most——] In a certain singularity, Xia You's voice is serious:

"The singularity determines the survival of humanity. The only question is how determined we are to defeat it——My dear servants, have you decided who will self-destruct next?"

An Zhiyu traveled to the Land of Shadows, training day after day, year after year, with his master Scathach. In the evenings, after martial arts training, he would receive instruction in magic from Morgan le Fay. Initially, he and Morgan le Fay got along well, and he formed a favorable impression of her.

Then, one day, Morgan le Fay suddenly said, "In a week, the King's Choice will begin. My sister Artoria will extract the Sword from the Stone and become king... I need your help with something."

"What?" An Zhiyu asked.

"Before her, extract the Sword from the Stone, and marry her."

"???"

"The curse has been activated. From today on, you must find a way to marry Artoria!"

This was a world where timelines intertwined. He had extracted the Sword from the Stone, resolved the conflict between Scathach and her sister, and aided Gilgamesh. An Zhiyu thought he would continue his adventures like this.

Until one day, he was summoned by the Holy Grail.

Looking at the group of old acquaintances in front of him, An Zhiyu waved his hands awkwardly: "Hello..."

Artoria smiled and raised the holy spear in her hand:

"Shine in the End of the World!

[Day 1 of the time travel: Wearing Adi King's battle suit and dark red hair, is Emiya Shirou actually me?]

[Day 3: Confirmed, this isn't the UBW questline, no Red A experience packs, so I'll have to rely on myself to master Unlimited Bladework.]

[Day 20: Strengthened my magic proficiency and began practicing Projection. During this time, I met an alchemist who asked me where I got all these alchemical weapons made from recycled metal.]

What the hell is recycled metal?

[Day 90: Finally mastered my first Noble Phantasm, Projection. They exclaimed, "This is the Seven Kingdoms," an outstanding achievement in alchemy."]

Huh? I don't really understand you alchemists.

...

[Day xxx: Huh, I finally mastered Unlimited Bladework! Their expressions were fascinating, and they asked where the Nibelungen was.]

How come you don't even know about the inherent barrier? Isn't this... Type-Moon!?

As a master who traveled through time, lan 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 saying 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. ] lan had to say that this simulator that understands people's hearts is really suitable for

him.

Solve all problems in his favorite way.

Everything looks good.

Until the moment they came to him.

Why does Ryunosuke Yusheng commit suicide frequently?

Why did Tohsaka Tokiomi hunt down his disciple?

Why doesn’t Jin glitter cooperate with the emperor?

Why is my king homeless?

Behind all this, is the distortion of human nature or the loss of morality.
