Following the record-breaking success of Demon Slayer: Infinity Castle – Part 1 in 2025, renewed attention has been drawn to one of the series’ long-standing questions: Why was Tanjiro Kamado, the protagonist and one of the strongest demon slayers, never promoted to the rank of Hashira?
Although Tanjiro achieved power on par with, or even surpassing, several existing Hashira members by the end of the series, he never officially received the title. The answer lies not in a lack of strength, but in the formal criteria for promotion and the timing of the Corps’ dissolution.
Understanding the Role of a Hashira
Within the Demon Slayer Corps, the Hashira are its highest-ranking members elite warriors who serve as the backbone of humanity’s defense against demons.
Each Hashira represents mastery over a distinct Breathing Style, serving both as a leader and protector within the organization.
The known lineup includes Gyomei Himejima, Giyu Tomioka, Sanemi Shinazugawa, Shinobu Kocho, Mitsuri Kanroji, Muichiro Tokito, Obanai Iguro, Tengen Uzui, and Kyojuro Rengoku.
As the story progressed, Rengoku’s death and Tengen’s retirement left vacancies, yet no new Hashira were ever appointed, despite the rise of potential successors such as Tanjiro.
The Three Official Paths to Becoming a Hashira
There are three recognized ways to ascend to the rank of Hashira within the Demon Slayer Corps. Tanjiro, despite his achievements, did not formally fulfill any of them.
- Becoming a Tsuguko (Designated Successor) of a Hashira: This path involves direct mentorship under a Hashira, preparing one to inherit the position. For example, Kanao Tsuyuri was Shinobu Kocho’s Tsuguko. Although Tanjiro received training and guidance from Giyu Tomioka, he was never officially appointed as his Tsuguko.
- Slaying Fifty Demons as a Kinoe-ranked Slayer: Demon Slayers of the Kinoe rank who independently defeat fifty demons can qualify for Hashira consideration. While Tanjiro demonstrated exceptional combat ability, official records of his rank peaked at Hinoe, one level below Kinoe, and there is no canonical record confirming that he met the required count.
- Defeating a Member of the Twelve Kizuki (Upper or Lower Moons): This is the most prestigious and direct route to promotion. While Tanjiro participated in major battles against Kizuki such as Daki, Gyutaro, Akaza, and Hantengu, he never defeated one entirely on his own. His victories were achieved through teamwork, often with the assistance of Nezuko or other allies.
Timing and the Dissolution of the Demon Slayer Corps
Even if Tanjiro had satisfied the criteria, circumstance and timing prevented his official recognition.
After the final battle against Muzan Kibutsuji, the Demon Slayer Corps effectively disbanded. With the eradication of demons, there was no longer a need for an organized military hierarchy or the title of Hashira.
By the series’ conclusion, Tanjiro’s abilities had undeniably reached Hashira level. Yet, the end of the Demon Slayer era closed the door on any official promotions.
From a narrative standpoint, Tanjiro’s journey was never about titles or ranks, but about empathy, perseverance, and humanity. His strength was defined not only by his combat skill but by his unwavering compassion and resolve to protect others the very essence of what the Hashira symbolized.
By not officially becoming a Hashira, Tanjiro represents the idea that true heroism transcends formal recognition. In essence, he embodies the spirit of the Hashira without ever needing the title.
