The Hashira Training Arc is Kimetsu no Yaiba’s Tenth arc. A few days after the Swordsmith Village incident, the leader of Demon Slayer Corps organized a meeting with all of the Hahira. They talk about Nezuko and the strange marks that appeared on Mitsuri and Muichiro that day. Following that, they decided to have mark training or Hashira Training for anyone who had obtained the mark.
Seven days after the Swordsmith incident, an emergency Pillar Meeting was held at the Ubuyashiki Estate. In attendance are Sanemi, Iguro, Muichiro, Mitsuri, Gyoumei, Shinobu, and Giyuu. Amanemi Ubuyushiki is attending the event in place of her husband, who is unable to attend due to illness. They talk about Nezuko and the strange marks that appeared on Mitsuri and Muichiro that day, and Amane explains what those marks are. Most of the first swordsmen who were on the verge of defeating Muzan had these marks. Since many people brooded about not having the marks, this information was hidden. Over time, the information had become unclear, but one thing that was passed on indefinitely was that whoever had the mark began spreading it to others who met the qualifications. In this generation, Tanjiro was the first to receive it, but when he was asked how it felt, he had difficulty describing how it felt. As a result, Amare asks Mitsuri and Muichiro for help. Mitsuri tries, but only embarrasses herself when all she can come up with is vague descriptions based mostly on how things felt. Muichiro has an idea, though, of what qualifications were met to make the mark appear.”
The Hashira Training is a one-of-a-kind training session taught by the Hashira that aims to improve the abilities and physical health of all Demon Slayers. The training is divided among the Hashira. First, Tengen Uzui, the Sound Hashira, performs basic stamina training. The Love Hashira, Mitsuri Kanroji, then handles flexibility training, while the Mist Hashira, Muichiro Tokito, handles quick movement training.
The Serpent Hashira, Obanai Iguro, then concentrates on sword skill revision, followed by the Wind Hashira, Sanemi Shinazugawa, who handles pounding training, and lastly the Stone Hashira, Gyomei Himejima, who focuses on muscle reinforcement. The Insect and Water Hashira, Shinobu Kocho, and Giyu Tomioka do not take part in the training. However, due to Tanjiro Kamado’s drive, the latter participates in the session.
The majority of Demon Slayers regard the training session as an eternal journey to hell, except Tanjiro Kamado and Inosuke Hashibira, who see it as an opportunity to develop themselves. Hashira is required to attend each other’s training sessions as a matter of course. It is seen as a win-win situation for both the Hashira and the Demon Slayers since even the Hashira gains from being assaulted by wave after wave of juniors graded lower than themselves.
