In the world of Demon Slayer (Kimetsu no Yaiba), beyond the gripping story and stunning animation, fans are especially captivated by the Nichirin Swords, blades that symbolize the Demon Slayer’s unwavering will. For collectors and cosplay enthusiasts, knowing the owners, their ages, and the stories behind each sword is essential.
Here, we answer some of the most popular questions and explore the legendary swords wielded by these characters.
1. Tanjiro Kamado: The Successor of the Sun Breathing & Wielder of the 'Scarlet Sword'
As the soul of the story, Tanjiro Kamado’s journey moves countless fans. A common question from newcomers: Is Tanjiro related to Yoriichi?
The answer is no, but there’s a bond deeper than blood.
Tanjiro is not a direct descendant of Yoriichi Tsugikuni. His ancestor, Sumiyoshi, was Yoriichi’s close friend. Yoriichi entrusted Sumiyoshi with his Hanafuda earrings and the technique of Sun Breathing, which later evolved into the Kamado family’s Hinokami Kagura. This legacy awakened in Tanjiro, becoming the only hope to defeat Muzan Kibutsuji.

Is Tanjiro a demon?: In the finale, Muzan injects Tanjiro with his blood, temporarily turning him into the new Demon King, granting him Muzan’s powers and resistance to sunlight. With Kanawo’s medicine and the support of his friends, he regains his human form.
