Did the Heroic Spirit I conquered become a reality?

Yu Tohsaka, the adopted son of the Tohsaka family, embarked on an unexpected journey after stumbling upon a game disc. He entered the game world and encountered Tiamat, only to find himself in a peculiar situation - instead of being the heroic spirit, he was the one being saved. Despite this, Yu Tohsaka completed the system task and spent a wonderful time with Tiamat, eventually completing various game routes. In one scenario, he was King Arthur's childhood sweetheart, while in another, he had a devoted lover named Sajō Aika. After completing the game, Yu Tohsaka was about to put the disc away when, to his surprise, all the Heroic Spirits he had previously "conquered" in the game arrived at his doorstep, including the Knight King, Enchantress Morgan, Tiamat, and the Princess of the Red Court.
