Type-Moon: I Can Summon Heroic Spirits Without Limit, So I’m Invincible

He transmigrates into the FA world and becomes a real man, Kairi Shishigou. With the Great Holy Grail War about to begin, Shishigou plans to use his knowledge of the story from his previous life to strike hard and claim the Grail!

“What? Why can't I use a catalyst to summon a Servant? How am I supposed to take part in the Great Holy Grail War then?!”

Turns out I have an FGO System. Well, that's fine! As long as I roll enough times, I can get an unlimited number of Servants!!

I don't care about any of that “kneel facing southwest at twelve o'clock to get lucky” nonsense. I only believe in the Rule of Three: how long can a kid cry for?

Amakusa Shirou: “Jeanne, I advise you not to stand in the way of my wish!! Wait, this isn't Saint Jeanne d'Arc! Why are you an Avenger?!!!!”

Goetia: “I had only just become a Beast when I saw five Grand Servants waiting there with their swords drawn. How am I supposed to fight that?”

Gilgamesh: “I refuse to comment. Some jerk keeps bringing a bow to steal Heracles and camping outside. Every time he sees me standing on a streetlight, he ambushes me!”
