Hashira Training Arc

The Pillar Training Arc is the tenth arc of Kimetsu no Yaiba.

Synopsis
The Pillar Training conducted by the pillars is a special training session that aims to improve all demon slayers' abilities and physical health. The training is split between the pillars. First, the Sound Pillar Uzui Tengen conducts training on basic stamina. Then the Love Pillar Kanroji Mitsuri handles flexibility training and the Mist Pillar Tokitou Muichirou deals with the quick movement training.

The Snake Pillar, Obanai Iguro, then focuses on sword skill revision, followed up by the Wind Pillar Sanemi Shinazugawa who handles pounding training and finally the Rock Pillar Gyomei Himejima who trains muscle reinforcement.

the majority of the demon slayers view the training session as an everlasting trip in hell, with the exception of Tanjirou Kamado and Inosuke Hashibira who see the session as a chance to improve themselves.
