There are infinite possibilities out there and one single change can determine another's fate, that being the case of Yuto Einzbern Emiya the only son of Shirou Emiya and Illyaviel Von Einzbern. In this possibility the Hero Of Justice never married the King of Knights instead he married the little sister he sought to protect. Now their son along with his siblings are transported to the world of the three factions during the end of the Sixth Holy Grail War. With the Holy Grail Destroyed and in Fragments a New Grail War has started to reclaim them, Yuto's mission is simple and clean win the war and collect the Grail Fragments. Maybe help some people along the way. Note: This is an alternative story to Highschool DxD: Unlimited Blade Works, it will be called the Einzbern Route. I do not own Highschool DxD or The Fate series nor do I own any characters I used in this book from other anime, I simply own my OC.
