Although relatively calm and mature when a situation calls for it, Yoruichi is quite laid-back and playful, often teasing or flirting with those younger than her, such as Ichigo Kurosaki at the underground hot spring, a younger and hot-headed Byakuya Kuchiki, Suì-Fēng before her time as a captain, and Kisuke Urahara, childhood friend, former underling, and fellow ex-captain. Yoruichi prefers to drink milk, which fits with her practice of transforming into a cat.
