Li Lin: I was dragged to the Fourth Holy Grail War, but I'm not a Master, and I'm not a cheater. How can I win? I'm waiting online, it's urgent. Aige: The Holy Grail War is so simple, but if it ends too quickly, the honeymoon will be ruined. How can I make them stronger? I'm waiting online, it's urgent. "The bread here is so cheap. Is there a discount because I'm the 100th customer?" "No, that's not the case." "Why?" "Because my name is Sajo Aige, and I—love you."

[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.

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!

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!"

I have a fiancée named Guye; I have a bunch of lolis at home, named Illya, Miyu, Chloe...

I also have a very large fan club named Type-Moon.

Life should have been very happy, after all, I have a house and a car, but - Guye: "Tianyang, the world will of XX world has sent a message, asking you to go there to solve the change."

Mashu: "Senior Tianyang, it's bad, Miss Nobunaga went to Honnoji to demolish the house!"

Holmes: "Master, I heard that Moriarty went to blow up the Reichenbach Falls, do you want me to stop him?"

Tianyang: "Oh my God! Can you guys just be quiet?"

Talented in Magecraft but useless in physical combat?

Can summon 10,000 Servants but can he defend the rear by himself?

I will say just one line in reply:

“That will not be a problem!”

This is the tale of a young man who obtained an enshrined miracle.

“As long as I have my familiars, I am undefeatable!”

OK, now the question is, I have traveled through time, I have a beautiful sister who is above everyone else and has a brother-control attribute, and this sister looks very familiar, how can I avoid having my legs broken and sent to the Germans next door?

In addition, I also met a very gentle sister Marta, a purple old woman and her big black dog, how can I survive in such an environment, waiting online is really urgent
