Did You Do Anything Wrong When You Were a Servant in the Holy Grail War?

People are often willing to pay any price in order to compete for the miracle that can grant any wish. However, miracles are only given to one person and have value precisely because of their uniqueness. Therefore, in order to aim for further transcendence and height, he quickly uses his own strength to prove that he is the strongest person. When the synthetic human who was supposed to be a container showed a belief that did not exist in the first place, and when the soul who did not want to see tragedy was unexpectedly summoned to the world, this time, with a different Holy Grail War and different Servants, will the end of the story have a different ending? (A new author, I wrote this book purely to give the Fifth Holy Grail War a better ending, please forgive me)
