The Hashira Training Arc (柱はしら稽げい古こ編へん Hashira Geiko Hen?) is the tenth arc of Kimetsu no Yaiba.
The Hashira Training conducted by the Hashira is a special training session that aims to improve the abilities and physical health of all Demon Slayers. The training is distributed among the Hashira. First, the Hashira of sound, Tengen Uzui, trains in basic endurance. Then, the Hashira of love, Mitsuri Kanroji, takes care of the training of the flexibility and the Hashira of the mist, Muichiro Tokito, of the training of the fast movements.
The Serpent Hashira, Obanai Iguro, then focuses on revising sword skills, followed by the Wind Hashira, Sanemi Shinazugawa, who handles pounding training and finally the Stone Hashira, Gyomei Himejima, who leads to muscle building. The Insect and Water Hashira, Shinobu Kocho and Giyu Tomioka do not take part in the training. However, the latter takes part in the session thanks to the motivation of Tanjiro Kamado.
The majority of Demon Slayers view the training session as an eternal journey through hell, except for Tanjiro Kamado and Inosuke Hashibira who see the session as a chance to improve. As a general rule, Hashira must participate in the training sessions of others. This is considered a win-win situation for both Hashira and Demon Slayers, as even Hashira can improve by constantly being attacked by waves of juniors of lower rank than themselves.
