Demon Slayer: Inheritor of the Sun Breathing

He bears the face of Yoriichi Tsugikuni and wields the Sun Breathing, yet his strength falls short of the legendary swordsman's—and his personality is the exact opposite. "I couldn't protect anyone I wanted to protect," Guxuan laments. "I'm a worthless man." But the Demon Slayer Corps knows the truth: it was Guxuan who led them to slay Muzan Kibutsuji, and Guxuan who saved them time and again when they faced certain death.
