Poney

Poney is a member of the Empire's Assassination group The Elite Seven. She is an expert hand-to-hand combatant, easily overpowering opponents while unarmed. She is also dimwitted, taking Gozuki's advice of "use your head" literally by smashing her head into one of her opponents during her first mission. She adores Gozuki and gladly completes orders he gives her, and seems to actually enjoy fighting and killing her targets. Poney, along with other children, was picked to be put through a test in order to select candidates for The Empire's assassins. She was able to get one of the highest ranks and get into the elite group. She uses the Shingu Yocto-bottoms. (Source: Akame ga Kill! Wikia)
