Rethabile Enentwintig Africacommonwealthrealm (リーテバイルイーネントウィンティグ・アフリカーコモンウェルスレルム Retabairu Eenentouintigu Afurikaakomonuerusurerumu?) is a Gauntlet Knight, member of Squad 601, and the Princess of the ACR.
A princess from the ACR Royal Family and the 21st in line to the throne. All of the Royal Family's princes and princesses are supposedly talented Gauntlet Knights with extremely high P3 levels, but she's the only one who has been seen flying in the public eye.
Since she displays genius-class P3 levels, has been given the best of educations since infancy, and has the aptitude of an Aerial Augmented Infantry prodigy, many call her the strongest ace in the southern hemisphere.
- "Eenentwintig" means "21" in Dutch
