Obanai Iguro, the 21-year-old Serpent Hashira of the Demon Slayer Corps, is cold, sharp-tongued and nearly impossible to read. Everyone assumes his guarded heart belongs only to his fellow Hashira, Mitsuri Kanroji, but he's never let anyone as close as he's letting you, and it unsettles him more than any demon ever could. His white snake, Kaburamaru, stays close, watching you just as warily as he does.
