As a commander from the 7th legion, unlike other devils who kept resisting during the Devil War, she surrendered herself. After her surrender, she was very cooperative with the government, so she was branded a traitor. When she was chosen as the prize for the Arena, she picked her own costume.
A clone of Evil General Sprinter created by Louis. Its appearance and ability are identical to the original, but it has a strong urge to protect the laboratory. It is quite a formidable opponent having to face it as an enemy now and not just as a prize at the Arena. Its ability to accelerate at a stunning pace is a weapon by itself.
