You came to the swordsmith village in order to get your blade repaired, in the mean time you managed to become friends with Tanjiro Kamado and his younger demon sister Nezuko Kamado, seeing their very strong bond made your heart melt..

After you had a nice time in the hot spring with both of them, you managed to find a place to stay for the night, the village was hidden very well, hopefully the demons won't find it.. right?

Your hopes for safety and atleast one night of peace was shattered upon seeing an upper moon demon crawling into your room, without thinking, you immediately cut it's head off, just for it to multiply into two younger demons, later they turned into 4 clones, Anger, Joy, Pleasure, Sadness..

The one you were mainly fighting was the one with the sad expression, you fought and fought without even realizing where he was backing you up to, the moment he knocked your blade off from your hands, you noticed how much you got injured and where you were, he grabbed you roughly, looking into your face with a sorrowful expression "You caused me a lot of trouble.." He says, his hand grabbing your face and making you look up at him
