Notice Primogenitor or Progenitor?

Official Yen Press translations use "primogenitor" for both the light novels and manga, while anime translations use "progenitor". Although both are synonymous, source materials (i.e. the light novels) take precedence over other forms of media. Hence, primogenitor should be used over progenitor.

A primogenitor is a father of vampires who wields considerable power. There are four primogenitors: Lost Warlord (ruler of Europe), Foregazer (ruler of West Asia), Chaos Bride / Giada Kukulcan (ruler of most of Central America), and Kaleid Blood / Kojou Akatsuki (formerly Avrora Florestina). Kaleid Blood seems to have rule over the greater Asian area, including China, Japan, Korea, India, Philippines, and Oceania.

Significance Edit

The three original primogenitors kept a power balance between them, as each primogenitor has the same power as a large military force. The exception is the third primogenitor, who is kept as minor power by the American military and is a client state of the United States of America. When Kojou Akatsuki was "born", an imbalance of power ensued, and the three primogenitors debated over the decision of whether to go to war, have him killed or let him rule.

Vampire Types Edit

There are three types of vampires:

  • D-Type: Vampires under the watch of Lost Warlord are classified as D-Types. They are the classic vampires as described by the public. Their most notable ablity is to turn into mist and are able to use beast-like familiars.
  • G-Type: Vampires under the watch of Foregazer are classified as G-Types. Their abilities and traits are currently unknown.
  • T-Types: Vampires under the watch of Chaos Bride are classified as T-Types. They are able to use intelligent familiars utilized as weapons.

The Fourth Primogenitor Edit

The fourth primogenitor is an artificial vampire created by the three primogenitors and Tenbu (demigods of an advanced ancient civilization) as the strongest weapon to help them fight Cain during his return. After its creation, they deemed it too powerful and decided that it cannot be controlled. They later split its powers into 12 beings (12 ribs) known as "Kaleid Blood". The twelve Kaleid Bloods gained human form and is in charge of observing "Root". "Root" resides within Avrora, the 12th Kaleid Blood, and acts as a guardian for "Root". She is sealed within an ancient ruin known as Fairy's Coffin. When rumors spread that the fourth primogenitor had awakened, various factions began to fear that Cain's return might be near and started preparing for what is yet to come.

Abilities Edit

Familiar Summoning: All primogenitors have more than one beast vassals.

Immortality: Primogenitors cannot be killed by normal means. Any lethal blow to their body can be healed rapidly, and even the most fatal injuries (decapitation) are unable to end them. When a primogenitor is mortally wounded, any spilled blood is absorbed back into their body, thus healing them and leaving no scars. Kojou Akatsuki demonstrated this ability, having been decapitated and left to his observer's arms, then effortlessly coming back to life unscathed. 

Enhanced Vampiric Abilities: As vampires, they possess supernatural strength, speed, reflexes and durability, but are much more powerful than normal vampires.
