The Hunter is the main protagonist of Bloodborne: The Death of Sleep.
The Hunter dons the typical Hunter Set, armed with a Saw Cleaver and a Hunter Blunderbuss. Very little of its actual face is visible when wearing the Hunter Hat, but it can be seen that the hunter has a tanned complexion and pale blue eyes with feminine features. When unmasked, the hunter reveals an androgynous appearance, possessing short, frizzy white hair.
The hunter is first seen within the burning district of Old Yharnam slaying numerous beasts. It is implied that the hunter has been stuck in the night of the hunt for an extended period of time, as it vaguely remembers the victims of its slaughter. Soon, it rendezvous at a cathedral and is greeted by Retired Hunter Djura and numerous other hunters within. Djura presents the hunter to a frail child with pale skin. Though the hunter is initially dismissive, the child reveals itself to bleed white blood, to the hunter's shock. The hunter deduces that the child is Paleblood and decides to escort it to safety to transcend the hunt. A beast raid suddenly interrupts things, with the hunter taking up arms and telling the child to stay put. Amidst the chaos, the hunter comes face to face with a Blood-starved Beast, but the beast quickly overpowers and kills it. Reawakening at the Hunter's Dream, the hunter, now longing for death, is greeted by The Doll and Gehrman. Gehrman tells the hunter that if they truly want to be free from the night, it must seek Paleblood to transcend the hunt. The hunter teleports back into Yharnam where they are to relive the exact same circumstances as before.
Soon, the hunter reunites with the child, escorting it into the outskirts of Yharnam and into the Forbidden Woods to seek a certain healer who could be of use. Both look behind them to view the city of Yharnam from a distance engulfed in flames, the same Blood-starved Beast staring back at them atop a building. After a grave encounter with a Great Snake Ball, the child and hunter, now deeply wounded, descend into the 1st Floor Sickroom where they are treated by a sympathetic Iosefka. Iosefka asks for the hunter's gender, with the latter replying with "I am...A hunter." The hunter returns to the hunter's dream where it confirms to Gerhman that it has found Paleblood, though Gerhman is less than conclusive. The hunter and Gerhman discuss the morality of their actions, though Gerhman implores the hunter that they should leave, lest the "Presence" overhears their conversation.
Returning to the clinic, the hunter encounters the same Blood-starved beast lingering in the interior, though it is unaware of its presence. Iosekfa quickly tells the hunter to come through a door leading to her library before it takes any action against the beast. Within the safety of the blood-library, Iosefka prompts the hunter to leave so that the risk of contaminating her clinic alongside her patients is minimized. Iosefka says that once they leave, she'll lock the doors behind, and the hunt can continue. The hunter replies that it is no longer concerned with the hunt and instead asks her for a map to the Fishing Hamlet so that the two can procure a boat. The hunter swears that it will "help the child escape" from the nightmare. The child, much to the hunter's surprise, remarks to the two that it made the beast leave the clinic, it's white-colored blood trailing down it's nose.
After a period of time, the hunter and child are seen traversing through a desolate valley, now engaging in casual conversation. The child then asks if it it could borrow a cloth, to which the hunter asks why. The child, blood pouring out of it's eyes, nose and ears responds with "My eyes. I can't see." The hunter is later seen piggy-backing the unconscious child, contemplating on the validity of the child being Paleblood and how it was able to deter a monstrous beast. However, the hunter still notes that the Blood-starved Beast is continuously stalking them from afar. At an isolated ruin, the hunter makes camp for the two to settle. The hunter asks the now healed child of it's origins. The child responds with that all it remembers is "a sea of fog". The child then asks if the hunter is worried about the beast above them, to which the hunter responds with that it cannot see any beast. Concluding that it was mere faulty eyesight, the child decides to fall asleep. At the top of the ruins, an Amygdala stares down from the two.
The next day, the two take leave, the Amygdala still watching them from afar. Time passes, with the two crossing vast empty lands until taking rest at another ruin, a hunter's corpse with a Whirligig Saw nearby. The child sleeps as the hunter stays awake, contemplating the fact that sleep was now but a memory as the only thing it remembers is the hunt. Soon, the Blood-starved Beast catches up and the hunter takes arm with the Whirligig. After a brief battle, the beast pins down the hunter, now accepting its fate. However, the child walks up to the beast and implores the hunter to cover it's ears. Suddenly, the child extends it's jaw and lets out an ear-curdling screech, the beast splitting into two and killing it once and for all. Perplexed, the hunter then asks for the child to help it up.
The two finally arrive at the Fishing Hamlet, seemingly abandoned. The child looks up at the hunter and asks "it all began here didn't it?" The Hunter sees beast-like footprints within the muddy path ahead of them, citing that perhaps the Hamlet is not as abandoned of its villagers as it seems. The Child points to a note written by Gehrman on a billboard. The note reads that the hunter would never know what Paleblood truly is, and that he cannot tell when nightmare ends, only that he is weak and wishes to be free from it soon. The hunter scrunches up the note and throws it away. The child announces to the hunter that it is getting weaker, with it being too weak to walk and the hunter forced to carry it. The hunter wanders through the desolate village. The child, its nose bleeding, asks the hunter if it sees "them". To which the hunter sees nothing. From the child's perspective, three Amygdalas are looming over them. The child guides the hunter through one of the monstrous Great Ones, cautious not to disturb it. However, the child's voice becomes more and more sickly and inhuman, and the hunter soon looks down and sees that it is holding the child no more, but a grotesque monstrosity. Terrified, the hunter drops the malformed child and vomits, the child citing that perhaps it is not what it seeks after all, and that it may have been human once. The hunter brandishes its Saw Cleaver and prepares to kill the beastly child, but its plea "is that you, uncle Djura?" stops it in its tracks. Coming to terms as to why Djura was so protective of the beasts in the first place, the hunter refuses to kill the niece/nephew of the old hunter. Instead, the two get into a rowing boat and sail into the misty ocean, awaiting whatever fate has in store for them.
