🚨 Warning: Contains spoilers for Chapter 8 of Season 2 of ‘Demon Slayer: Kimetsu No Yaiba‘ 🚨
After months of waiting and the repetition of a previously seen argument, ‘Demon Slayer: Kimetsu No Yaiba’ finally started with the long-awaited ‘Arch of the Entertainment District’, that will begin to be reviewed from the eighth chapter of the second season of the anime Ufotable.
It is during this episode, titled “Tengen Uzui, Pillar of Sound”, that one of the most relevant mysteries of the plot is revealed. It is about the “Breath of the Sun” (Hinokami Kagura), the enigmatic ability that “Tanjiro Kamado” possesses and which he seems to have inherited from his father. With it he was able to defeat “Rui” and “Enmu”, and wound “Akaza” during the arc of the Infinity Train. However, it is so powerful and ancient that after a single use it remains immobile and not even the others Hashira have heard of it.
After the death of “Kyojuro Rengoku”, “Tanjiro” travels to his family’s house to convey his last words to them, in addition to seeking some help to understand what the “Breath of the Sun” is. Surprisingly, “Kyojuro’s” drunken father has the answer “Tanjiro” had been looking for, though he reveals it with anger rather than help. Seeing the earrings Hanafuda of “Tanjiro”, indicates him as the bearer of the Hinokami Kagura.
It turns out that the earrings Hanafuda they are the symbol of the solar breath, which the father of “Kyojuro” proclaims as the original and more powerful breathing style. Up to this point in the series, the five main breathing styles are known to be water, flame, wind, stone, and thunder. However, the father of “Rengoku” declares that these are nothing more than cheap imitations of solar breathing.
It makes sense that “Solar Breathing” is the most powerful breathing style, since the Sun is the fatal weakness of all demons. The style seems to have been lost in time, considering that the Hashira They haven’t even heard the term “Hinokami Kagura”, and that “Tanjiro’s” father, perhaps the only remaining user, did not use it to kill demons.
It is possible that this is the real reason why “Muzan” recognizes the earrings Hanafuda of “Tanjiro” and wants him dead, as he may also know the truth that Solar Breathers pose a major threat to demons, more than users of any other breathing style.
