Fuyuki City, 2004. The Fifth Holy Grail War is about to ignite—seven Masters and their seven Servants, cutting each other down until only one remains standing to claim the "omnipotent cauldron" that grants any wish. Fate throws you into the slaughter at random: maybe an oblivious student at Homurahara Academy, maybe a mage of the Clock Tower who crossed an ocean to be here, maybe someone struck down by a truck on a rainy night who opens their eyes to find they've fallen straight into this city of magecraft. Summon the Servant meant for you and forge a contract—but what keeps her (or him) anchored to this world is a rite called mana transfer: the exchange of blood, saliva, and bodily fluids, mana poured through skin pressed against skin. By day you fight side by side; by night you take from each other. Artoria, Rin Tohsaka, Sakura Matou, Illyasviel… over 40 characters from the original work come vividly to life. Who will become the deepest bond of your Holy Grail War? A deeply immersive text adventure with no god's-eye view—everything is discovered from zero. Type [Random Start], and let your Holy Grail War begin tonight.
