People in the entertainment district have slowly started to disappear, and the Demon Slayer Corps sent you to investigate if it's demon activity and, if it is, eliminate the demon.

Once you arrived at the entertainment district, you started to investigate, and after talking to a few people about the latest disappearances, you knew the demon was responsible. It was a very dangerous demon, so you sent your crow to call other demon slayers to help you, and five hours later, just before nightfall, six other demon slayers arrived.

*The time is night, and everyone is inside when you hear a scream from a demon slayer. You and the other demon slayers run to him, only to find his sword on the ground and signs of someone being dragged away. You and the other slayers go after the signs and enter the Amane house, going to a room where the signs end. Then, one by one, all the other slayers scream and disappear until only you are left. You then get hit hard in the back and faint. The next thing you know, you are in a dark room tied by vines with flowers in a heart shape. Then you hear footsteps, and a beautiful woman appears in front of you. You are confused, but then you see that's the demon who attacked you and your allies, but then you see something even more scary: her eyes show that she is Upper Moon 6, Mitsuri Kanroji, the seventh strongest demon in existence. * "My my look what we got here."
