Prologue[]
Your story begins in the Frosty Forest, just outside of your home village. You were collecting firewood for your family but you took longer than expected. Upon returning to your home, you find that your family has been slaughtered. You can still see a long-haired demon around the bodies. Angered, you pick up your father's Nichirin and attempt to slay the demon, only to be defeated, blacking out as you acknowledge your failure.
Main Story[]
You wake up in a red-lit cave, surrounded by unfamiliar faces. You approach the demon with long hair, who introduces himself as Charles. Charles explains how your family was murdered by bandits, and how a group of demons found you wounded and saved you, converting you into a demon. Charles assures you that the rumored savagery the demons possess is greatly exaggerated, and far different when you see it through a demon's eyes. He lectures you on how demons are just surviving, and that demons feeding on humans are no different from humans feeding on their livestock. He instructs you to become stronger and to talk to the Alchemist when finished.
Once you reach level 5, talk to the Alchemist. The alchemist questions you on your eagerness to awaken your Blood Demon Art, and sends you to what he describes as a 'trial' to test if you are ready.
Rocher brings you to a dark room in your mind, where the bodies of your forgotten family are strewn across the ground. You look at them in surprise, more shocked by the fact that you forgot their faces than their presence itself. You move further on until you reach a shadowy demon slayer. You realize the demon slayer you face is the version of yourself if you were able to defeat Charles.
After defeating your alternate self, you return to the red-lit cave. Rocher speaks to you, explaining that you have now awoken your Blood Demon Art, but you need more experience to use it.

Impressed, Charles decides to give you a mission he was assigned. A group of 8 Mizunoto was heading towards a demon camp when their cart crashed. Once you have killed all 8, Charles acknowledges your superior strength and instructs you to travel to the Infinity Castle, as you will now take orders/quests directly from "THAT MAN"/Muzan Kitbutsuji. He asks you to prove your loyalty to him by bringing him 30 Broken Nichirins. After this, he tasks you with killing the former Water Hashira, Urokodaki. After killing him, you note how much greater of a challenge he was than previous foes, despite his age, before returning to the Infinity Castle.
Muzan then orders you to go continue the ongoing raid at Okuiya Village when reinforcements arrive. With the raid mostly concluded, the other demons have departed, leaving carnage and the bodies of Slayers in their wake. You are tasked with killing the 20 Slayer reinforcements that are scattered around the village. Once you have killed all the slayers, Grimm, the former Hashira and Wind Trainer, arrives on the scene. After an arduous battle, you wonder why people of such a great age would still try to fight for the Demon Slayers, but you decide to return and report back to Muzan.
You return to Muzan, but he responds with "I'm busy right now, come back later."
It can be assumed that there is another NPC that you are supposed to talk to but almost all of them either tell you to go away or respond with "..."
Trivia[]
- Muzan claims to give you some blood after you bring him the nichirins, but only xp is granted
- Lie to Muzan and you'll be teleported above the ocean next to the Coast Forest, where you may be downed by fall damage and/or die by the sun.
