Millianna has been friends with Erza ever since childhood. She even loves to give out nicknames to her friends. She can conjure magical tubes that constrict or stretch on her command to bind or attack opponents and prevent the use of magic (Nekōsoku Tube), along with the ability to scratch her opponents, leaving them with imprinted scars (Secret Weapon: Scratch Attack) and crossing her legs around her opponent’s neck in a seated position and repeatedly punching them in the face (Cat Punch).
