Elizard

Elizard (エリザード) is the Queen of England in the Toaru Majutsu no Index series. She's the mother of Rimea, Carrisa, and Villian. She carries a replica of the Sword of Mercy, Curtana Second, which allows her to send Telesma to the knighthood and people within the extent of England's territory. The Original Curtana grants its wielder power equal to that of the Chief of Heaven's Army, Archangel Michael, as long as its wielder is within the territory of England. Her replica, Curtana Second, can use 20% of the Original's power.

Ten years ago before the beginning of the series, a faction of the Parliament tried to sacrifice the third princess Villian in the process of eliminating all of France’s military force, both magical and otherwise. If it weren’t for Acqua of the Back ignoring the political constraints and helping Villian, she would’ve died. After that, Elizard gave them a severe punishment using Curtana Second, and the Royal Family has retained the power to rule over the United Kingdom instead of politicians due to that incident.

During the Civil War in England, she appears before Carissa and turns the power of Curtana against her by sending the sword's blessings to all on England's soil.

Her magical ability has been commented by Index to be even more impressive than the Index Librorum Prohibitum in some ways, as the aforementioned move to weaken the Original Curtana's power was assumed to be something beyond Index's own capabilities.

Design evolution
Elizard's design remains static throughout the series. Haimura did not need to design her to be moe, as such her design is much more subdued to show the "liveliness" of those who were acting as main characters in the volume she was introduced.

Trivia

 * Elizard is based on Queen Elizabeth II of England.
