Bloodborne's story is set in a gothic horror world full of beasts and dark secrets. You play as a hunter trying to uncover the mysteries and survive the nightmarish encounters.
In an old, dilapidated mansion on the outskirts of town, there were rumors of a bloodborne horror. A group of curious teenagers decided to explore. As they entered the dark hallways, they felt a cold chill. One of them found a diary that told of a family curse. Soon, they heard strange noises. Out of the shadows, a figure emerged, its eyes red with bloodlust. They ran for their lives, but not all of them made it out of that blood - soaked place.
I'm not entirely sure as I haven't read it specifically. But generally, it might be about the dark and gothic world of Bloodborne, perhaps exploring the characters' journeys, the terrifying creatures, and the mysteries within that game - inspired universe.
