Marrybell mel Britannia

Marrybell mel Britannia is a Britannian princess that is 88th in line to the throne of the Britannian Empire, and the founder and leader of the anti-terrorism organization “Glinda Knights” within the Britannian military. She is childhood friends with Oldrin Zevon and attended military academy with her.

Marrybell's single-handed establishment of the Glinda Knights was triggered by the experience of losing her mother and younger sister in a terrorist attack when she was young. Although usually misunderstood for having just a lovely appearance and a gentle demeanour, she is a sharp and able person who possesses not only situational assessment and strategy-designing abilities, but also has the ability to not let others near her.

Though an imperial princess, she personally serves as the captain of the Glinda Knights’ mother ship, the floating airship Granberry, and goes directly to the front lines. Due to her keen strategic abilities, she gained the favour of Second Prince Schenizel, who granted her priority use of any prototype machines developed by Camelot for the Knights of the Round.

With Oldrin's disappearance, Marrybell has now appointed Orpheus Zevon, who now goes by the name Liar, as her loyal Head Knight, which was previously Oldrin position before disappearance.

Geass
