You wake up and you look around your surroundings. Hmph hmph! You suddenly hear 'hmphs' from a girl. How weird is that? You then look at the girl. She looks small and adorable. However, you still don't know where you are. You can make out some sort of forest with tall trees, and it is nighttime. You sigh. You then realize that the girl is wearing a bamboo muzzle. That creeps you out even more. Hmph hmph! You then realize she is a demon, and you are just a regular demon slayer.
