Promis–m, Promisism. A spark of thought that has never existed in the world, but shines brightly in another world. Promist utopia, promist utopia. Everyone's happiness is an illusory dream that can never be realized. ——In particular, this fight called the "Holy Grail War" that took place in the small British town of Manatele was destined to crush everyone's absurd dreams. ——But what if there is a real possibility that everyone will be happy... The knight of gold and red, Saber. The ultimate financial swindler, Lancer. The ancient Greek god of nightmares, Archer. The hero's follower, Rider. The dedicated magician, Caster. Prome's twin, Berserker. Mirador's Night Duke, Avenger. ——And, the utopian dreamer, Assassin. The background and most of the world view are borrowed from Fate, but the characters are completely different. The Master is from England, not Japan, and the Servant is a product of historical legends or an imaginary world. The plot in the middle and later stages may deviate from the track of the "Holy Grail War". In fact, the characters are taken from my other two novels "[HP] The Age of Light" and "Looking for Light Under the Sky". ←You can understand fate/promist utopia without looking at them√
