Waking up on the operating table. Durin had originally thought that saving humanity was all he needed. But then—Fuyuki's 'AI', BB-chan, who's trying to conquer the world, invades Chaldea, wanders the Far East, sharpening her knife to find the murderous woman I killed, and the Root Girl, who comes looking for Saber, is completely unreasonable—and then there's a silver-haired Leo woman who wants me to be her right-hand man and acting director of Chaldea. Hmm... This is probably a world where even messing around with Gudafu & Gudako won't be enough to survive!

You awaken by the lake and crush the holy sword you just pulled up. You capture a young blond girl and place a collar on her. You take a spear and name yourself Longinus. You approach Joseph's gate and stab Maria in the chest. Become a legend within the simulation as a villain, and you'll gain a spiritual power the size of the Andromeda Galaxy. Punch the power of the Yangzhi force, trample the alien god. Susa: "Hahahahahaha."

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?"
