FGO Crossover: Something About My Game Seems Different

More than three years have passed since the Sword Art Online incident. Since then, similar full-dive games have gradually appeared around the world. The most popular at the moment is the newly released Fate/Grand Order by TYPE-MOON. Wanting to play with her friends and simply being interested in the game, Kishinami Hakuno logged in too. But she soon realized... Why is my game different from everyone else's?! Why isn't Mash my starting Servant?! What am I supposed to fight all by myself?! My adventure quests seem wrong, too! (The Servants who fought over a chance to appear and ended up missing their window: ...) And on top of that, I seem to have an easy time pulling the gold Servants that other people can never get... Not long after, Kishinami Hakuno, who had been obsessed with the game lately, decided to take a break and focus on studying as her exams approached. But then the game's Servants all appeared in the real world?! That's not scientifically possible! Fujiwara Ritsuka: What's even less scientific is that the world you're in now is actually a fusion of the worlds you once saved. You're super famous in the hidden world, Zabi-ko-san. ○ Sequel to the love-triangle aftermath. I know I haven't finished filling in the holes in the prequel, but I can't control my imagination. ○ Zabi-ko is tentatively without a pairing; her future is undecided. ○ Fujiwara Ritsuka♀ x Mash. Gudako is usually gentle and shy, but turns chaotic evil at crucial moments. She has awful luck with her pulls. ○ Dr. Roman survives. ○ The timeline is a mystery.
