Liala

Liala is the daughter of a prestigious Duke Household and the adoptive older sister of the current Demon Lord, Leohart. For some reason, she underwent an atavism, which made her look more like someone from the God Race. From her first appearance, Liala has almost always been shown smiling, possessing a playful, gentle, curious, and childish demeanor around several high-ranking people more so her adoptive younger brother she is noted to love more than anyone else. Despite her childish demeanor, she is highly perceptive and intelligent, as well as serious at times being able to figure out that both Jin and Basara were planning on killing the Demon Council if she hadn't done so herself, as well as the latter being responsible for Belphegor's death, however, she plays all this off as being apart of her woman's intuition. Liala can be ruthless against anyone she views as a threat to Leohart or makes attempts on his life to the point of being referred to as the Massacre Demoness, which was further noted as Leohart stated she wouldn't hesitate to turn her anger toward the people responsible for the birth of Shiba, such as the Hero and God Clans if he died during the events of Volume XI.
