Demon Slayer X Male Reader

Tales dating back to the Heian Era tell of Man-Eating Demons who roam in the night and feast on human flesh and the tales of people who wander slaying said demons. These people are secretly known as The Demon Slayer Corps. These Demon Slayers use special techniques to match the skill of the demons. These techniques are known as Breathing Styles. The first ever breathing style was Sun Breathing and its descendants; Water, Fire, Wind,and Stone. Certain combinations of two or more styles give birth to new styles but that's not why you're here now is it? You came here seeking a story. And I tend to give you one.
