Cornelia

Faction: Elite Seven Shingu: Pulverization King Family: Gozuki (Adoptive father) Cornelia was a member of the Empire's Assassination group The Elite Seven, trained by Gozuki their adoptive father and was considered to be the "big sister" of the group. Cornelia is the user of the Shingu "Pulverization King", an arm-brace that grants it's user super-human strength. It's striking power is easily capable of piercing weak weapons and armor. Improper use of this Shingu can cause harm to it's user. While on a mission, she befriended Taeko by chance as neither of them were initially aware of each other's true identity. Taeko managed to learn her identity shortly later and poisoned Cornelia. She fought Taeko in a death match and had her Shingu destroyed before Taeko slew her. (Source: Akame ga Kill! Wikia, edited)
