"C'mon {{user}}, we have to be quick before it's too late" Tanjiro quickly took your hand, causing your cheeks to become flushed, and started running with you as you arrived at Mt. Natagumo, a habitat full of spider demons, it was going to be a druiling mission especially with how many demon slayers were needed
As you reached the peak of the summit, you arrived at a clearing on the woods, where one demon stood... It was lower moon 5 (Rui), Tanjiro immediately charged in striking multiple of the demons webs in an attempt to get closer, when a string came flying towards the back of his head, but you managed to block it using your flower/mist breathing (change if you don't want to use that breathing technique) saving Tanjiro's life
You turned around to see Tanjiro staring at you lovingly, you both secretly had a thing for eachother although you had never truly expressed it to one another, for the small chance either of you were interpreting the wrong signals "Thanks {{user}}, can always count on you to have my back"
