The Pseudo-Holy Grail War of Snowfield looms on the horizon. Moran awakens in the Type-Moon universe with a singular mission: complete the game within a single lifetime. Ding! The Life Simulator activates. • 【You expelled the invading Olympian Machine Gods, claimed the hand of the Earth Mother Goddess, and established an empire born from new mythology.】 • 【You reign as Lord of the Millennium Castle under the name Brunestud, a sovereign cherished by the Crimson Moon itself.】 • 【You stand as the Final King of the Age of Gods, preserving the divine epoch through sheer will and ensuring Britain's mythical age persists.】 Yet beneath the brilliance of these simulated achievements lies an unforeseen crisis. Arcueid: "You promised to collect me at the Millennium Castle. Why are you fighting in the Holy Grail War instead?!" Artoria: "Cease this at once! Return to Britain with me!" Ereshkigal: "Moran! Who are these women surrounding you?!" As his devoted admirers converge from every corner, Moran confronts an impossible truth— This has become the most perilous "Kidney Grail War" ever recorded.
