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."

Shirou: Huh? Messenger of Justice? What's that? If you love your sister, go fight in the Holy Grail War. If you can't even kill six people in a row, and you can't even take down an EA, what's the point of being a sister-con? I always take it with my face, understand? Excuse me, young man next door, but you actually need Saber to help you fight in the Holy Grail War? I always tear people apart with my bare hands, okay? You can't even tear a Servant apart with your bare hands, and you're still calling yourself Gudako's dad? Have some shame! Today, I'm going to teach you how to fight the Holy Grail War! ...

Bai Ming, 20, is a time traveler from China, having journeyed to the Type-Moon world. A member of Chaldea's A-Team, he beats up werewolves, slaps lovers, argues with gloomy, withdrawn girls, intimidates schoolgirls, and knocks out insomniacs. He owns a simulator system and fears the world isn't violent enough.

"I traveled to Type-Moon and gained the recognition of the Root. As long as I can die an abnormal death, I can ascend to the Throne of Heroes and become the Lord of the Throne of Heroes, an existence that is stronger and freer than the Seven Crowns." "For this reason, I started to act like a fool in Type-Moon." "I scolded Gilgamesh to his face, challenged the almighty Zeus in Greece, openly kidnapped Skadi in Northern Europe, declared that Solomon was a demon god instead of the Son of God in Israel, and stood on Morgan's side in Britain..." "But why am I still alive now?" 1994, Fuyuki. A famous figure in history, the third friend of the Most Ancient King, the first prime minister of Mesopotamia, the man favored by the Greek gods, the king of giants in Northern Europe, the incarnation of God who awakened Solomon's humanity in Israel, assisted by Prince Camelot... The young but weathered-looking Lovi sat on the top of the Fuyuki Bridge, sighed, and looked at the scene in front of him: "Tell me, what went wrong here?" "Or, you kill me and let me ascend to the Throne of Heroes? Please!" Kiritsugu Emiya lit a cigarette, glanced at Artoria who was holding the Holy Spear next to him, the King's Treasure unfolded by Gilgamesh, the red spear tip extended from the Kingdom of Shadows... The hand holding the cigarette trembled slightly.

(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.

[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.

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.
