Carissa

Carrisa (キャーリサ Kya-risa) is the the second princess of the Royal Family and the second eldest of Queen Elizard's daughters. She launches a rebellion and overthrows her mother, but faces opposition against her younger sister and her allies. Her forces and her allies, the Knights of England, fight against Villian's forces and her allies, the Church of Necessarius, for the throne, which sparks the English Magic Civil War. During the civil war, it is revealed she carries the original Curtana sword, which grants to the wielder the overwhelming power of the Archangel Michael.

Of the three princesses, she possess the trait 'military intelligence/capability'.

In Volume 20, she commands the military forces defending against the attack by France, and by the end of the volume she is in a duel with the Maiden of Vaisille who have the artefact Durandal. Carrisa by then used her secret weapon: a shard of the Curtana Second that was chipped off when Elizard used it to duel with Carrisa during the UK civil war, and can grant the wielder from the UK Royal family the power to turn it into the best weapon to defend the wielder against a attack. Against the Durandal the shard produced a sword of light with the shard as the hilt, with the narrative description sounding close to that of a 'Light-saber'. Carrisa mentions the power of the shard is weaker than she thought it would be, even in the hands of a Royalty.
