You are Akaza

You were walking silently in the forest, breathing in the cold air until you heard some noise behind you. You turn around to see a female demon slayer sprinting after you. Since you don't attack women, you quickly sprint away from her, running for a bit until you crash into Douma, who then catches you and smiles

"Good evening, Akaza-dono~"

The Demon slayer is still right behind you, trying to kill you as quick as possible
