Sanguinem

Sanguinem is the third capital of the vampire world, located underneath the ruined city of Kyoto. It is home to prominent vampire nobles, such as Ferid Bathory and Krul Tepes.

Details
In the manga, Sanguinem is a large city beneath Kyoto. It is extravagant with buildings in 18th-century design, churches and cathedrals, and elaborate archways. There are also European-style houses. The ground often consists of either tile or stone. The city is set at one level, but many buildings have multiple stories. There are numerous large pipelines throughout the city.

In the anime, Sanguinem is an elaborate and large city composed of several bridges and waterways. There are many levels to the city. The buildings are designed in an 18th-century style, although some modern structures also exist. The churches and cathedrals are not shown, and the large pipes do not decorate the buildings.

Society
As the capital, Sanguinem is a center of politics in the vampire world. Important issues are discussed in the city, and it may serve as a meeting place for powerful nobles. It is not surprising that numerous vampires reside in this large city. Ferid Bathory lives in the city in his mansion, whilst Krul resides here as vampire Queen of Japan. Humans also live in the city, serving as livestock for the vampires. Most of these humans are children, and many were brought here during the Apocalypse in 2012 like the children from the Hyakuya Orphanage. Some of these children were sent by Kureto Hīragi to act as his spies and gather information from the nobles.

The vampires are not allowed to drink human blood directly from the livestock within the city. In the manga, the vampires remind the humans that they live at the mercy of the vampires, but they are not violent toward them except during rare instances, such as when Ferid Bathory killed the Hyakuya orphans.

In the anime, the vampires are regularly violent toward the livestock, going so far as to even step on children drawing in the street and dangling Yuichiro Hyakuya off the edge of a bridge when he misbehaves.

The livestock are raised to believe the world above ground has been destroyed, so they have no reason to escape. Unlike in the vampire cities above ground, the livestock cannot come and go freely as long as they do not know the locations of the exits.

Prologue
Yuichiro, Mikaela, Akane, and other children that survived the Apocalypse on Christmas of 2012 were deported to Sanguinem from Tokyo to become livestock to vampires. Krul specifically collected the children from the Hyakuya Orphanage because she wanted the surviving seraphs. Four years later, Mika stole a map and gun from Ferid Bathory, and he attempted to escape with his family of orphans. Ferid waited at the exit for them, slaughtered most of them, and dismembered Mika. Only Yu escaped into the outside world.

Shinjuku Arc
In 2016, the vampires in Sanguinem discussed the growing threat of the Japanese Imperial Demon Army. Krul declared war on the JIDA for the crimes of killing their kin, stealing their territory, and dabbling with taboo magic.
