鬼滅の刃 2 [Kimetsu No Yaiba 2] by Koyoharu Gotouge

Continuing the young swordsman’s quest to restore his demon-turned sister, this volume follows his early missions as a newly minted demon hunter: he faces haunting, cunning foes that test his senses and resolve, hones his breathing-based sword technique in desperate battles to protect the innocent, and forms tentative bonds with fellow hunters while confronting the tragic humanity behind some enemies—discovering that compassion can be as crucial as steel in the fight against the night.
