The next day.
The Demon Slayer Corps launched a large-scale special training program called [Ten Hashira Training].
All swordsmen ranked below the Hashira had to take turns undergoing each Hashira's special training.
Ten Hashira Training was actually conducted by the seven Hashira other than the Ice Hashira, Lin Guang, the Insect Hashira, Shinobu Kocho, and the Water Hashira, Giyu Tomioka.
It began with Tengen Uzui's rigorous training to improve the swordsmen's basic physical fitness.
Next came Mitsuri Kanroji's hellish flexibility training and Muichiro Tokito's high-speed movement training.
Then came Obanai Iguro's swordsmanship correction training, Sanemi Shinazugawa's endless beating training, and Gyomei Himejima's muscle strengthening training, followed finally by Kyojuro Rengoku's comprehensive combat training.

And since he believed the final battle was imminent, Lin Guang was not in the mood for that sort of thing. He merely shared some tender moments with the two women before returning to Demon Slayer
