La Folia Rihavein (ラ・フォリア・リハヴァイン, Ra Foria Rihavuain) is a princess of Aldegyr. She is the eldest daughter of Lucas and the niece of Kanon. She was pursued by Magnus Craft because they wanted the blood of a person from the Aldegyr royal family for their experiments. She becomes Kojou's third blood partner in order to activate his third familiar and save Kanon from Magus Craft.
La Folia is a beautiful girl with clear, sky- blue eyes and long white-silver hair. She carries a medium-sized curse pistol with a knife attachment, similar to that of a bayonet, and appears to be a very skilled shooter with it. She wears a jacket-like trench coat, with a white button-up shirt and black skirt. She is seen wearing a blue pendant gemstone with red ribbons, possibly indicating her royalty status. She also has golden chains looped around her left shoulder.
La Folia seems to be quite a cheerful young woman who is also quite friendly. Even though she just met Kojou, she seems to care for him as much as Yukina does for him. She also willingly desired to help Kojou when he was injured, and such was giving him her blood, to which he would drink later on in order to awaken the Third Familiar with the help of Yukina's blood as well. As of Episode 15, she jokingly stated "I can't produce a heir with him like that" referring to Kojou stuck in Yuuma's body.
She comes to protect Kanon Kanase. And not much else is known

|The Artificial Holy Sword||La Folia has the ability to recreate the Artificial Holy Sword of the Völundr System seen in the prelude of Episode 9 (and fully in Episode 12 and 15) with her bayonet by temporarily converting herself into a spirit. When activating this ability she says the following chant:|
Enhanced Agility: La Folia is shown to be extremely agile in combat, allowing her to be able to jump several feet into the air.
- Chant:She can temporally turn to a spirt.
Daughter of the gods that is within me... Protector of armies, age of the sword, bringer of victory and deliverer of death!
Wagami ni yadore, kamigami no musume. Gunzei no mamori-te. Ken no jidai. Shōri o motarashi, shi o hakobu mono yo!
- Basing in the anime, La Folia is the only one who may have an intent of having a heir from Kojou.
- She have another enchant with her weapon: Wagami ni yadore,
kamigami no musume. Tate no hakkaisha. Kyō to Arashi. ¡Shōri o motarashi, shi o hakobu mono yo!
