As the protagonist, Tanjiro fighting the main villain of the series at the end of it all should be a given, as there are few other ways a story would end. With the true nature of the Hinokami Kagura also comes an idea of the importance Demon Slayer 's Tanjiro is due to have in the fight against Muzan. It was already clear that the Hinokami Kagura was a powerful technique, but it’s now been fully established as far above its contemporaries. In Demon Slayer season 2 episode 8 - the first episode of the “Entertainment District” arc - Tanjiro learns from Rengoku’s father that the Hinokami Kagura’s true form is Sun Breathing, the original Breathing Style that all others are derived from and the strongest one of them all. That plot point finally gets paid off in season two with the reveal of Tanjiro’s Breathing Style being the most important one in the story.

The first season ends with Tanjiro wanting to learn the truth, and part of the 'Mugen Train' arc's ending has the Flame Pillar Rengoku telling Tanjiro that there might be information about the Hinokami Kagura somewhere at his family’s home. Tanjiro was trained in the Water Breathing Style, but during his fight with the Lower Moon Demon Rui near the end of the first season, he suddenly uses a new, more powerful Breathing Style called the Hinokami Kagura, which was actually a dance his father, Tanjuro Kamado, taught him before his death as a dance. In Demon Slayer: Kimetsu no Yaiba, the titular Demon Slayers fight against demons using the Breathing Styles technique, which utilizes hyper-focused breathing to grant the user enhanced strength and reflexes to give them the power to kill demons with their specialized swords. In tandem with that, the anime has taken steps to set up the level of importance Tanjiro and his family will have in the story in a major way. After spending nearly two months recapping the Mugen Train movie, season two of the anime has started moving the story forward with its “Entertainment District” arc. Season two of Demon Slayer: Kimetsu no Yaibahas just dropped a major reveal about Tanjiro Kamado in its latest episode. Warning: Contains spoilers for Demon Slayer: Kimetsu no Yaiba season 2.
