Fate: the Holy Grail Is in My Hand from the Beginning

I traveled to Fuyuki City, and the system forced me to participate in the Holy Grail War, but the Holy Grail was also given to me. Then can I just declare victory? But the system smiled and told me that I could try it. In the end, I tried it, and it almost cost me my life... The system deceives people, he really deceives people. In short, new articles for newbies, something anti-routine. If you like fate, jump in quickly. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
