There were a few novels that met this requirement, such as Sword Immortal who joined the chat group, Infinity from the Giants, and The Final War of the Apocalypse. The protagonists of these novels were involved in the Holy Grail War, but the main content of the novels was not the Holy Grail War. It involved different worlds and storylines. If you're interested in these novels, you can read them. I hope you like my recommendations.
πI recommend the following books to you:
1. "Emiya Ilya"-If you like the story of Ilya as the main character, this novel is very suitable for you. It tells the story of a partner of justice replacing Emiya Shiro to become Emiya.
2. "Starting from the Holy Grail War"-This novel has system and card drawing elements. If you like this kind of metaphysics novel, don't miss it.
3. "Yuki's Holy Grail Journey"-This novel involved many pre-ordered worlds, from Fate Zero to the original Holy Grail War. It was quite interesting.

Well, friendship or camaraderie between the masters and servants can be a common theme too. Sometimes, they form strong bonds that go beyond just the goal of winning the Grail. Also, there's often the theme of redemption. Some servants or masters might be seeking to atone for past sins through their actions in the war. For example, a servant who was a villain in their original legend might try to do good in the Holy Grail War fanfiction.
Well, the 'holy grail war of shirou fanfiction' is all about taking the basic premise of the Holy Grail War from the original work and adding a unique spin with Shirou. For example, it might explore what would happen if Shirou had a different upbringing in the context of the Grail War. Maybe he has different ideals that change how he interacts with the other Masters and Servants. It can also be about exploring his relationships in more depth, like his connection with Saber in new and interesting ways.
πI recommend you a novel called Conan: The Correct Way to Make a Wish on the Holy Grail. In this novel, a Holy Grail vessel was reincarnated as the child of a fox demon after the Holy Grail War, and its identity became even more special. This Holy Grail also had an older brother and an uncle who was a cross-dressing boss. The life of the non-human Holy Grail was very rich and interesting. Every day, he enjoyed the love of many shikigami. I hope you like this fairy's recommendation. Muah ~π
Shirou is obviously a main character. Often, Saber would still be a major part as well, since she has a strong connection with Shirou in the original story. Other Servants and Masters from the original Holy Grail War concept might also appear.
As far as I know, there is no official novel about the disintegration of the Holy Grail War. However, for this theme, I recommend "Infinite Valoran","Sword Immortal Joining the Chat Group", and "I, the Great Hero of the Palace, Travel the Heavens!" Waiting for the novel, I hope you like this fairy's recommendation, muah ~π
"A Master's Moon-Shaping Event Book" was a novel about Dante's transmigration to the Holy Grail War. It was a light novel and a derivative doujinshi novel. There was no harem. It was the same world view as the new book,"I'm a Sword Hero in Moon-Shaping." The author was from the Land of No Return. I hope you like my recommendation. Muah ~
Yes, I recommend the following two novels to you: " A Master's Calendar of Moon-shaped Incidents " and " The Holy Grail War Begins with the Black Shadow Corps." The former told the story of the protagonist's struggle to win the Holy Grail War and protect the future, while the latter told the story of the protagonist being forced to participate in the Holy Grail War and become a villain after transmigrating to Winter Wood. I hope you like my recommendation.π
Fiction. While it uses some historical facts as a backdrop, the overall thesis in 'Holy Blood, Holy Grail' is a fictional construct. It weaves together various legends, like the story of the Holy Grail, in a way that goes beyond what historical research can prove. There are no reliable sources to back up many of its far - reaching claims about secret societies and the like.
