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....)

[Configuring Windows Update... 99%... Please wait] ...My name is Hiroki Sawada. I'm 10 years old and a time traveler. After crossing over, I live in an ordinary residential area in the Hidden Leaf Village and am unmarried. I attend the Ninja Academy and return home no later than 6:00 PM every day. I don't smoke and have no interest in alcohol. My favorite drink is Fat Otaku Sparkling Water. I'm currently a student at the Ninja Academy, excelling in theory and reasonably good in physical skills. I go to bed promptly at 9:00 PM every night and get a full eight hours of sleep. Before bed, I do 20 minutes of yoga to relax my body. Once in bed, I fall into a deep sleep. I sleep through the night, never letting fatigue or stress linger until the next day. Doctors say I'm normal. Of course, I'm only saying this to let you know that I don't have any lofty dreams...

Introduction: Traveling to the world of One Piece, without a system, without a grandfather, without a cheat code, as a pure Yanhuang person from Earth, Mo Ye was almost beaten to death at the beginning. Facing his weak body, Mo Ye said that he just wanted to survive, because only by surviving can there be infinite possibilities.

[The Great Demon King of Green Mountain Invites You to Join the Chat Group] After six days of being transported to the past, defying her original fate of becoming a velvet ball, the once despondent Miss Fox suddenly perked up and immediately sprang to life. Six days without video games, internet, or a cell phone—wouldn't that drive anyone crazy? Now, the chat group is here! The six days are over; it's time to return to the realm of video games!

I'm in the Honkai world, having just traveled through time. The question is, what's with this strange narration? [Take off! Take off! Such a wonderful start! Looking at this opening, you feel like your life is about to reach its peak.] No, it doesn't feel like it's taking off at all. Besides, the Honkai world is notoriously unfriendly to ordinary people, right? (╯‵□′)╯︵┻━┻. [There are many beautiful Valkyries to choose from.] [Even if you want to go big, there are Honkai Gods, Soulsteel Mini-Bishops, and Cyborgs as well.] [You feel like you're already fired up!] Not at all... Wait, Otto, you can do that? [Changkong City! The place where destiny begins! This is the perfect place for you to take your first step after traveling through time!] [Defeat the Herrscher of Thunder, then collect the Herrscher of Void and the future Herrscher of Reason into your crystal palace—the world is mine!] Wow, with this setup, you want me to go head-to-head with the Herrscher? I get it. You probably want me dead.

Traveling through Doupo Cangqiong, Xiao Chen obtained a heaven-defying system that could replicate everything.

I thought I could easily copy the strange fire and dominate the continent, but the system prompted: Insufficient energy, please recharge first.

In desperation, he had to cling to his fellow villager Xiao Yan's thighs, and by the way, copy some elixirs and skills to barely survive.

Until one day, he accidentally copied the ninth-grade Xuandan. The thunder of the dan shocked Zhongzhou, and the ancestor of the Soul Clan came to his door in person: "Young friend, would you like to pay? My Soul Clan will cover everything!"

Xiao Chen looked at the VIP15 exclusive privilege that popped up on the system interface - [Copy Ancient Dou Emperor], and fell into deep thought...

Iron Man Tokiomi Tohsaka, Kiritsugu Emiya (father of magical girls), Kariya Matou (dark swordsman), King Arthur (who spews profanities)... Captain Uchiha Sasuke (Bleach), Naruto Uzumaki (Primarch), Sakura Haruno (true progenitor of the vampire clan)... The Marvel Universe, teeming with heroic spirits and visitors from parallel worlds; Digimon from the Pokémon world; a crossover world invaded by supernatural tales; EVA, where Ultraman descended... In each world, beings that shouldn't exist have appeared, bringing a worldview-destroying shock to the inhabitants. "Yes, I did all of this. As the Fourth Calamity, wielding the 'Funny' system and with the profession of 'Masked Fool,' it's perfectly reasonable for me to do things that make people's vision go black, right?" "What? You're asking what those people who saw another version of themselves in a parallel world and were driven to nervous breakdowns think?" "I think..."

The full title of this book is "The Story of Miss Gudako, who almost became the Burial Mechanic's Agent at the Cathedral Church, and after resigning, unexpectedly came to Chaldea to become a Master and save humanity" - a classic joke. This is a slightly clichéd FGO story.
