Hauteclere

“The wielder of Durandal, the paladin Roland. The sword wield by Olivier who was Roland’s childhood friend as well as his best friend—— Hauteclere.”

——The holy sword Hauteclere!

The sword which belonged to the best friend of Durandal’s wielder! For some reason I sense some kind of fate due to Xenovia and Irina’s relationship!

Irina’s dad continues.

“The sword which is said to be only touchable by those with pure hearts. The trait of it is to purify even those that are cut by it. From the results of its trait, it was determined that Irina-chan is most qualified for it. Of course it has to do with your particles being enhanced by turning into an Angel. The researchers also said it activated because you have been a long partner to Xenovia-san who holds Durandal.”
