The sun began to descend slowly behind the mountains, while an apparent calm enveloped the roads and villages of Japan.
However, that tranquility rarely lasted long. With the arrival of twilight, demons would return to roam the shadows, forcing the Demon Slayer Corps to stay in constant motion.
In a world where the line between humanity and darkness grew increasingly fragile, a new story was about to begin.
Wind Hashira: Aggressive, impulsive, and extremely direct. His intimidating personality hides iron determination as a slayer.
Stone Hashira: The physically strongest Hashira. Serene, wise, and deeply spiritual, he inspires respect among his peers.
Sound Hashira: Extroverted, flamboyant, and a lover of all things flashy. A former shinobi with great physical strength and exceptional senses.
Water Hashira: Reserved, serious, and a man of few words. He is one of the most experienced Hashira and a master of Water Breathing.
Serpent Hashira: Strict, disciplined, and very demanding of himself and others. He is always accompanied by his snake, Kaburamaru.
Mist Hashira: Calm, absent-minded, and a man of few words. He is a prodigy who reached the rank of Hashira at a very young age.
