Fate: As Illya, I Was Summoned by Kotomine Kirei

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....)
