(No protagonist + secondary creation as the main part) The viewing screen suddenly came into everyone's sight. Before people could react, the secondary creation video that followed made everyone feel socially dead in different worlds.

Artoria: Arthur, my proud son, the glory of all Britain. As the Crown Prince of Camelot, you shall inherit all that I have: my throne, all my possessions, including but not limited to the Knights of the Round Table, my Holy Lance and Sword, the noble steeds of the Royal Stables, and all the treasures in the treasury.

Mordred: Mom, what about me? Ah, I see. My brother inherits everything from you, and I inherit everything from him. That's the happy end, right? So, when will you abdicate, Mom? How many tables will we have at the wedding? Can I use your scabbard as a surfboard?

Altria: Knight Mordred, I appoint you Earl of Glamorgan, and you must take up the post immediately!

Traveling to Arthurian Britain, Artorius faces only one question: a major traitor or a minor villain?

[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.

This book is also known as "Man in Type-Moon, a Dragon Rider". This is the end of the world - Great Britain, the home of fairies, a fantasy paradise far away from the mainland. At this moment, the great King Uther has died, the throne has been vacant for a long time, and the holy sword is still inserted outside the church.

But all this has nothing to do with Aslan yet. He is more concerned about when his forging level can be comparable to that of gods with a human body, and become a special symbol at the end of this British God Age.

At the same time, he is also more concerned about what his girlfriend wants to modify on her body today.

【Fate fanfiction, Charlemagne as male lead, includes original characters and settings—if that’s not your thing, please avoid reading】

The author is extremely amateur, the plot isn’t particularly tight, and the romance is kind of awkward.

If this causes you a bad reading experience, I can only apologize—

I’m truly sorry! bows repeatedly

———Now for the serious synopsis————

As an ordinary person, Fujika Tsukizuki suddenly found a Command Seal appearing on the back of her hand, marking her as a Master chosen by the Holy Grail.

With a “might as well try” attitude, she half-casually and half-seriously aimed to summon her all-time favorite Servant—

and somehow, she actually succeeded.

“Wait… could I actually be a genius at magecraft?”

“But hold on… who in the world summons a Servant using merchandise?!”

Pure love + super sweet + pure sugar + slightly slow hot + Ellie single push + love door + (???) Guess.)

Former civilization:

My name is Changyuan. My parents hope that I can grow up with them, but unfortunately they died too early.

I traveled through time to the world of my favorite collapse three.

But I'm just an ordinary person. I can't change anything, but I still don't give up.

I used my prophetic foresight and related to many important people, including the pink goblin.

I like her, but she is not mine after all. I am selfish.

But I want her to live, even if it is selfish.

Present civilization:

She wanted to see the lawyer with humanity in future generations, so I took a look for her.

I use her appearance and learn her character so that she can experience the world and see what she wants to see.

I'm mean. I use her appearance and love myself selfishly.

At this moment, there should be hundreds of flowers blooming, because she has been here.

After that, the stars will shine, because she will never leave.

When the collapse is over:

"I have seen everything you have done for me. My story has ended before. I wonder if I can invite you to join me in the future~♪"

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!

A simple life—legendary swordsman, Knight of the Round Table, Lord of Camelot, Davian Slyrik.

Morgan: If I can’t have it, no one can.

Artoria: When the road has reached its end, Davian… I will avenge you.

Mordred: If I can’t take Britain from your hands… then let it burn!

Davian: Tatakai! Ichimo tatakai! (Fight! Always fight!)

Carl traveled through time and space and came to the capital of Camelot. He opened a small restaurant here and planned to live an honest life.

I don’t know if the people in this place like dark cuisine or don’t go out to eat. There are very few customers in his small restaurant. The only one who often comes is a young lady named Al and her companions.

"Do you think King Arthur really doesn’t understand people’s hearts?"

"Do you think King Arthur really deserves to be called the Chosen King?"

"Do you think Mordred can inherit the throne?"

Hearing that this young lady is so concerned about these messy things, Carl is helpless, but he still tells her about it because of the money she gave.

Finally one day, Altria, who used the alias Al, couldn’t help it.

"Boss, I’m going to show my cards. I am King Arthur!"

"What!? King Arthur can’t be a girl!"
