Leone (レオーネ Reōne?)
is one of the older members of Night Raid. She has a very relaxed and
cheerful personality, and tends to display a lack of ladylike manners. She serves as a sort of big sister figure to the younger members in Night Raid, often referring to herself as "onee-san". She does the same with Tatsumi, but it is heavily implied she has feelings for him, shown by her "marking" him as her own. Despite the morally dodgy nature she can sometimes display, Leone is not one to tolerate injustice, and can be especially vicious to those who commit the most vile acts.[ch. 8] She excels at gathering information and exercises calm judgement when necessary. Her Teigu is "Animal King Form: Lionelle" (百獣王化 ライオネル Hyakujū Ōka: Raioneru?),
a belt that increases all five senses and gives her animal-like
characteristics, as well as powerful regeneration. She is voiced by Yū Asakawa.
