[I needed about four hours to do all this and refresh my memories with the Dialover Stories]The red lines are the Vampire Blood Lines // The orange ones are the Demon Blood Lines and the blue ones are the First Bloods // People who just know the Anime could get a little confused Stuff that is written with (…) are no facts! Just thoughts! NOTES to the Family Tree
Menae and Krone were sisters so they had the same parents
That makes Cordelia and Carla and Shin to cousins. Because of the fact that Menae was a first blood who also died of Endzeit, Cordelia is ½ First Blood and also ½ Demon because of her father Burai Because of Cordelia's unpure blood she didn't get infected by the Endzeit when she got born.
Cordelia’s blood mixed with Karlheinz’s vampire blood makes the Triplet truly into devils! XDD They are ⅓ Vampire , ⅓ Demon and ⅓ First Blood.
The Demon Lord Burai and Menae are the Triplets’ grandfather and grandmother. And Menae is the aunt of Carla and Shin. The other way round Krone was Cordelia’s aunt. The same connection goes for Richter and Karlheinz’s unknown parents and Christa’s parents
Looking at the fact that Richter and Karlheinz are cousins with Christa, means, that their unknown parents had to be related in a way. Their mothers / fathers were sisters/ brothers or mixed siblings.
Mukami Ruki, Kou, Azusa and Yuuma are half Human / half Vampire(The fact that Yuuma’s real name is Edgar could mean, that the names Ruki, Kou, Azusa and Yuuma are just given by Karlheinz to make them forget about their human lives in their past / That actually also Kou, Ruki and Azusa have other real names)
All Sakamaki with their different mothers are half-brothers including Prince Kino. Subaru is their paternal half-brother.(Kino’s mother is unknown but was probably Karlheinz’s wife Nr.4 - That all wives have German names, maybe his mother also had / has one, too) Other Stuff that generally came into my head
All First Bloods have the ability to transform into the sub races of the Demon World: Wolf (Werewolf), Bat (Vampires), Eagle and Snake (Víbora).
The snake race King is also called the Víbora King. Due to circumstances Shin lost his left eye to him (First I thought they use Latin words but I checked it, in Latin Viper means “Vipera” but in Spanish it’s Víbora. So I assume the other races could be called the same way in Spanish = [Wolf race = Lobo // Eagle race = Águila // Bat race = Murciélago // Viper race = Víbora]) (On the Wiki they call the Vampire race just 'Bat Clan', I can see why XD The word for bat is way too complicated but I like the others!)
(The status rank would be then: The First Blood King Carla (even his race died of Endzeit, except of Shin) // The Demon Lord Burai (Cordelia’s father) and continuing with the sub races going with the known Bat Clan / Vampire King Karlheinz and the probably remain unknown leader of the Eagles (Águila King) and of the Wolves (Lobo King)
Demon Lord “Burai” (Jap. Burai 無頼) // Meaning: Villain / Rogue also worked together with Karlheinz for achieving his plans (His name is pretty obvious XD)
Shin and Carla’s Tsukaima are wolves (使い = Tsukai = Messenger // 魔 Ma = demon / evil spirit) // The Vampires (including the Sakamaki) own bats as Tsukaima
Tsukaima are controlled by their leader and are either there to attack other races or being used as messenger
Ever thought the theory that the Sakamaki plus Kino are the so-called “Seven Deadly Sins”?
Laito is the Lust.
Kanato is the Greed.
Shuu is the Sloth.
Subaru is the Wrath.
Reiji is the Envy.
Ayato is the Pride (The thing that remains is Gluttony, I wonder if Prince Kino is someone who eats a lot Konpeito while playing smartphone games, ignoring the heroine)
(If you read about the plans of Karlheinz on Wiki, damn, I can understand why Kino wants to kill them all c-c' (If that is his reason xDD)
