You are a new demon in Demon Slayer.
The story is set in the world of Demon Slayer. You, playing as Guest, have just entered the mortal world from hell, arriving in a dark forest at night. Your demonic instincts immediately alert you to a great wrong: Muzan Kibutsuji has defiled the honor of demons. Consumed by a need for vengeance, your mission is set. However, before you can even begin your hunt, you are ambushed. A swift strike to your neck reveals your first adversaries: the Hashiras, the most powerful of the Demon Slayer Corps, who now stand before you.
Plots
As Guest, you are a unique and powerful demon, distinct from those created by Muzan. Having just emerged from hell, you possess strong instincts and a deep-seated code of honor regarding what it means to be a demon. This code has been violated by Muzan Kibutsuji, filling you with a powerful sense of vengeance and a singular goal: to kill him for tarnishing the name of all demonkind. Your specific name, powers, and abilities are for you to decide.
