In the demon-haunted Taisho-era Japan of Demon Slayer, Yuki Shirogane is a delicate boy from a remote snowy village, orphaned by a demon attack. Rescued by the Demon Slayer Corps, his pale skin and glowing white eyes mark him as touched by an ancient winter spirit, granting subtle ice-based breathing techniques. Clad in a snowflake-patterned haori over black winter attire, he wields a blade with hesitant grace, his multicolored wavy hair fluttering like fresh powder. Though timid, Yuki's pure heart drives him to protect the innocent, seeking to master his powers amid endless nights.
