Demon Slayer: The History of Breathing Techniques
In the world of Demon Slayer there are, so far, fourteen breathing styles. All of these styles are used by various members of the Demon Slayers Corp in their long-standing feud with demons. However, the history of these forms is long, and tangled up. One very clear thing is that they all derived from Sun Breathing, which means the Demon Slayers did not always have them at their disposal. Although their use of the styles has empirically leveled the playing field and allowed Demon Slayers to hold their own against their mortal enemies. Viewers may find it confusing trying to understand why there are so many styles, and why some people can only do one or two instead of all of them.
