The beginning of all illusions is also the end of all journeys. Humanity's future must be created, expanded, and protected by humanity itself… not interfered with by those who lack the qualifications of "humanity." If you insist on interfering with humanity's future, who will you save? Without the Grand Order of the 48th Master, 'Fujimaru Ritsuka,' humanity is destined for destruction. And you cannot save anyone! As a parting gift, I bestow upon you a name. —Yuki Suzuki

This book is also known as "Uncle, I'll Help You Fight the Holy Grail War, with Meals?", "This Mapo Priest Is a Little Different", and "There's Something Wrong with This Illya".... Huh? How did I suddenly travel through time while taking a nap? And become Illya? While becoming a loli isn't a big deal, why do we still have to fight the Holy Grail War? And what exactly is the Holy Grail War? Can someone please tell me! "I'm a participant in this Holy Grail War, your Master, Kotomine Kirei. Please tell me your real name, Assassin," the seemingly respectable priest in front of me asked. Although she didn't understand what was going on, the little girl still responded politely: "Hello... Hello, my name is Illyasviel... By the way, uncle... do you provide meals here?" - In short, it's the story of Father Mapo summoning the assassin class Illya~ a well-behaved (and scheming) Illya who strives to help her Master~ (If you're not good at this introduction, please move on to the main text.) (Plot line: Fourth Holy Grail War - Fifth Holy Grail War - Magical Girl Illya, etc....)

On the eve of the Fifth Holy Grail War, unusual agitation was reported in the spiritual veins of Fuyuki City.

Rin Tousaka, a young woman who bears the honor of her family and the pride of a magus, chants the spell to summon the Heroic Spirits in her ancestral workshop. What she seeks is a sword sharp enough to sever her fate, a key to the "root."

However, the one who descended was the alien Herrscher who was supposed to dissipate in the cocoon of the end— "Nice to meet you, my dear little Master! Just call me Alicia♪"

The pink-haired, pointed-eared girl landed gracefully on the ground, holding a crystal longbow, with a sea of ​​stars in her eyes.

That day, Kiana was dozing off in St. Freya's class, Luminous had just arrived in Mondstadt, and Star, March 7th, and Danheng were still cleaning up the antimatter legion at the Black Tower space station. They were all about to embark on their own destinies, but that day, a screen suddenly appeared, instantly changing their fates. Along with the various fan-made videos playing on the screen, even the characters themselves were "given away."

After traveling to Fairy Britain in FGO 2.6, veteran Master Guinevere discovered a game called "Life Simulator," a simulation of future events. He used this simulator to find a perfect strategy for achieving a promotion, a raise, marrying a Heroic Spirit, and ultimately reaching the pinnacle of his life. Just as Guinevere was feeling confident, he noticed something was amiss. C Dai: "Wow, Guinevere needs so many resources to fully break down. I've already spent all my money on food this month." Bavanshi: "Altria! Get out of here! You're good at stealing men, but you don't have the courage to face me?" Bagster: "If you need money, you can give me Guinevere. I've already prepared 310 resources." Noknaree: "Guinevere, when I become queen, I will marry you in style!" Melyusina: "I'll just raid at night. You win, win, win, and in the end, we'll all lose." Morgan: "As long as I'm alive, he will always be my husband." Looking at the series of amazing cards they had spawned, such as [Guinevere, the Savior of the Holy Swords], [Guinevere, the Doom Dragon Knight], and [Guinevere, the Evil Tyrant], Guinevere fell into deep thought: "Wait, am I the character being nurtured?"

Altria: Rebellious son! How dare you snatch the queen from my father?!

Mordred: Ghost mother, that's obviously my brother!

Caught between mother, mother, mother, mother, mother, mother, mother... and my sister, the Shura field

Thanks for the invitation. I'm in Fuyuki, known as "Second Master." The Fourth Holy Grail War just ended, and Second Uncle just passed away... the timing is perfect. Right after the Fourth Holy Grail War, a boy named Matou Shinji begins to awaken his memories from before his reincarnation. He still remembers a joke he read online in his previous life: What's the first thing to do after transmigrating to Fuyuki City? Kill the bugs and save Sakura! Shinji looks at himself in the mirror... Hmm, time to wash up and go to bed. Ding! [Your system is online!] Sakura! Onii-chan is here to save you! ...Wait, something's not right. Why does this system sound so much like Siri?

[The strongest Fate fanfiction is here!] [Not a single one] As everyone knows, the life of Shirou Emiya is like Eevee in Pokémon. Picked up by different people, he experiences different things, giving rise to different species. Each has their own strengths, and their unique skills are truly astonishing, absolutely breathtaking...

What? In this timeline, Shirou's specialty is... using his incredible charm to garner favor?

Emiya Sakura: "Why are you so skilled at this?! Besides my sister, how many other women do you know?!"

The Chronicles of Emiya: The Super Heroic Tale, a prestigious serialized story!

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! ...

Chu Hang suddenly traveled to Changkong City in Honkai Impact 3 and was invited to a chat group that had traveled through time at the same time.

Kiana of the End: "I am the Ruler of the End who controls time and space, and I know the fate of all beings in the past and future!"

Traveler Ying: "I am Traveler Ying, who travels through the long river of time across billions of worlds. I master the seven elements and know the fate of all things!"

When Chu Hang saw this, he felt that there was something wrong with every member of the chat group, and they were completely inconsistent with their original personalities!

The next moment, Chu Hang saw the traveler Yingfa asking:

"@Chu Hang, why are you using my previous life's profile picture and the name Chu Hang?"

Kiana also noticed the blind spot and asked, "Indeed, what's going on @Chu Hang?"

After reading these two messages, Chu Hang guessed that the people who traveled through the chat group at the same time were all reincarnations of fragments of his soul.

So, Chu Hang, who was in Changkong City, sought the confirmation from Kiana, the post-collapse world, and gained a power, the essence of the authority of the end...
