Granberia, also known as the Swordswoman of Fire, is a member of the Four Heavenly Knights, who took part in the Monster Lord coronation battle royale in which a series of unfortunate events took place, involving Alma Elma forfeiting the battle on a whim and Tamamo and Erubetie knocking each other out. She brought Alice “to her knees” once but she was ultimately defeated due to Alice reading her skills. She is a dragonkin (dragons with humanoid appearances) abandoned at a young age, left in care of Salamander. She is 24 and is by far the youngest of the Heavenly Knights.
An expert in the arts of fire, she douses her blade with it to deal sharp damage. However, despite her title and main elemental attribute, Granberia is also capable of using wind, earth and water, having mastered the power of water at the age of five as well as showing mastery of the wind and earth. She mentions that these abilities are "natural" for a warrior, and the “attribute it’s associated with is meaningless.” She takes a lot of pride in her swordsman skills, and it is said that no one can match her abilities, at least until she was bested by Luka. Granberia is also a master of the Cursed Sword fighting style, the basis of all of Luka’s skills, though it’s quite clear their mastery of it is not on the same level. Granberia is also known to put herself through rigorous training to overcome any obstacle, stating to have had difficulty against Tamamo’s earth abilities in the battle royale and then trained and strengthened her abilities sometime later in order to be able to cut through a mountain and pierce Tamamo’s (and by extension Luka’s) defenses. Also, like all the other Heavenly Knights and Alice, Granberia is capable of teleportation and telepathy.
