Demon Slayer: My breathing technique went awry after Nezuko pushed me down.

While others master the art of demon slaying through grueling, traditional training, Shirakawa Yu takes a decidedly unconventional approach—starting with a rather strange inquiry to the nearest female companion: "May I smell it?" Unsurprisingly, this earns him a deadly smile and a raised blade of Wisteria poison from Shinobu, while Nezuko simply blinks in innocent confusion from the sidelines. Yet, beneath his eccentric demeanor lies a peculiar power born from a chaotic mishap involving Nezuko. As the final, desperate battle within the Infinity Castle unfolds against the terrifying might of Muzan Kibutsuji, Yu steps forward amidst a formidable gathering of allies and adversaries alike, unleashing a bizarre breathing technique that defies all logic. Step into a comedic yet thrilling supernatural adventure where the Demon Slayer Corps' greatest asset might just be their most unpredictable eccentric, surrounded by a growing roster of iconic heroines and reformed demons.
