Demon Slayer: Kimetsu no Yaiba―One-Winged Butterfly (Demon Slayer: Kimetsu no Yaiba Novels)

Shinobu and Kanae ask Himejima to teach them how to slay demons. After he refuses, they must complete the impossible task of moving a giant rock to convince him to introduce them to trainers. In other tales, Zenitsu tricks Inosuke into helping him dig a hot spring under Uzui's training, Mitsuri grapples with her reason for becoming a Demon Slayer, Genya discusses his family with Sumi, the Hashiras try to make Tomioka smile, and Kimetsu Academy forms a rock band-much to Shinobu's chagrin!
