Mukai was destroyed, and the Demon Slayer Corps finally ushered in peace. However, Tanjiro's sword, carrying the residual power of the thousand-year blood ghost technique, tore the curtain of time and space. Tanjiro, Giyu, Zenitsu, Inosuke and other core members accidentally fell into Tokyo shrouded in "curse".
There is no roar of ghosts here, but there is the raging of super curse spirits, and the invisible curse power weaves into a new purgatory. They mistook the cursed spirit for a new type of evil spirit, and fought bravely with the breathing method. It happened that Gojo Satoru carried Japanese knotweed, Fushiguro, and Kugizaki on a mission. When the Nichirin Sword with the power of the sun collides with the unlimited magic spell, the strong men of the two worlds go from misunderstanding to becoming side by side - the breathing method can purify the filth of the cursed spirit, and the spell can enhance the power of the breathing method. Su Nuo's thousand-year curse actually has the same origin as the infinite blood ghost magic, and Tanjiro's He sword is its ultimate nemesis.
From the collaborative training at the Conjuring Academy to the barrier battle in Shibuya, the Breath of Thunder breaks the spell, the Breath of Water purifies the filth, the Breath of the Beast restrains the enemy, and the Breath of the Flower strikes the core, breathing techniques and spells are perfectly integrated. They forged He Dao curse tools, used cross-border bonds as shields, and immortal faith as blades to charge towards Su Nuo at the top of the curse.
This is the pinnacle collision of breath and spell power, and a protective oath across dimensions - no matter what kind of purgatory you are in, light and bonds will always be the strongest force to pierce the darkness.
