Most shonen anime have amazing combat techniques and styles that are common in their universe. In the case of Demon Slayer, this appears in the form of breathing styles that are absolutely beautiful to witness. The grace and poise present in these styles are so striking that most people forget that their purpose is to behead powerful demons and cleanse the world of their horrors. It's the allure of these breathing styles that makes each and every battle in Demon Slayer feel like poetry in motion, with combatants giving it their all to augment their swordsmanship skills and take out tough enemies by whipping out every powerful technique they can employ in a battle.
