Leopard is a member of the Blue Guardians' Six Guards.
Leopard is a slim woman of average height. She wears a sleeveless shirt, briefs with an artifical tail, a cloth around her thighs and boots. She also wears pigtails on her head, her Dark Bring and a spiked collar on her neck, claws on her hands and bandages on her right arm. She also has some drawn stains on her right upper arm and both upper legs.
Unlike some of her male comrades, Leopard is not bad by nature and wants fly herself like a bird and be free, although she's not against killing other people by order as well. She is approval hungry and says that she hates something a lot. She doesn't like much things, especially being called a bug. She's also cruel, having fun with slaughtering many of Yuma's foster sons.
Leopard appears with Girafe on a beach after having a village destroyed. Then she appears with the other Six Guards at the gate to distract Haru's gang, allowing Lievre blast all of them away. In Yuma's base she slaughters all but one of Yuma's foster sons. Back at the ship she fights Julia and tells her how her Dark Bring works and the plan to her and defeats her right after that.  Later, she fights Elie and Nagisa and is defeated by the former after Elie learns how to use Etherion correctly.  Some time afterwards, she meets Girafe and tells him that she took a bug in Elie's shoe. Girafe despite having not having Lunar or Requin doing the search proceeds to torture Leopard with his Dark Bring for losing to Elie. She begs Girafe to stop, but Girafe responds with calling her useless and chokes her.
