Durandal

Durandal (デュランダル) is a magical artifact sword wielded by the Maiden of Versailles and said to be connected to the Royal Families of France and England.

Appearance
Durandal's blade is red with a gilded edge and guard.

Principles
Originally 's sword, due to the king inserting a shard of the Spear of Longinus into the hilt, Durandal is similar to the Curtana blades in that it is imbued with Telesma.

It is able to break through the Knight Leader's 'Thororm's Defense Formula', but only because the Knight Leader's spell has a deliberate flaw that allows England's Royalty's attacks to pierce through, as a sign he is loyal to the Royal family and not making a weapon against them.

World War III Arc
The Maiden of Versailles wields Durandal when she enters the Battle of the Dover Strait, bypassing the Knight Leader's defensive spell and clashing with Carissa's Curtana fragment-produced sword. She later uses it when she teams up with Carissa and the Knight Leader against Misha Kreutzev.
