Warumo had dark, shoulder-length hair, chiseled jawline and a well-built physique. On the night of his death, he was seen in a high-class nightgown.
Warumo's position in the Empire's government is unknown, but it suggests that he was of great importance as one of his subjects noted that he carried the future of the entire country on his back.
One night, Akame snuck into Warumo's room through the window and slit his throat with Murasame. Upon hearing the news of his death, Honest started to panic, while one of his subordinates mourned the late lord and swore vengeance on Night Raid.
