This became a traumatic event for the king of demons, who sought to kill anybody who possessed Yoriichi’s potential. Yoriichi was the only man who ever came close to defeating him.

This led to the creation of “five basic styles of breathing” to teach aspiring demon slayers.Īnother reason for the “extinction” of Sun Breathing is Muzan. Due to this, only a handful of people could learn Sun breathing.Īs Demon Slayers increased in numbers, most abandoned the hope of learning Sun breathing. While other breathing styles became popular, Sun Breathing was overshadowed as it was far more complex. Tanjiro’s ancestors were close friends of Yoriichi Tsugukuni, the progenitor of breathing styles. Now, Tanjiro is an important piece in the world of Demon Slayer, and so are the things he carries with him.įor example, his family heirlooms, the Hanafuda Earrings, and the Hinokami Kagura dance hold major significance as well. This also ties to Tanjiro’s case, who was originally a Water Breathing user and discovered Sun Breathing later.Īs we know, Tanjiro would go on to use both styles of breathing, further supporting what Rengoku had learned! Secondly, Rengoku adds that he has heard that black blade users can’t find a specific breathing style to master. Regnoku then explains more about the black blade users, which leads us to our next clue.įirstly, no black blade user has ever been a Hashira, tying into the assumption that demon slayers with this sword don’t live for long. This means that the color of a Sun Breathing user’s blade is unknown!
