The Schiff

The Schiff are soldiers created by a group of scientists led by Dr. Boris under the sponsorship of Amshel Goldsmith. They are created using Diva's blood.

Characterization
Trained only for fighting, they mostly know no other way of living or of getting what they want except by force. It is shown in the anime how they were raised very differently from humans, and even as they escaped the lab they were experimented on, they were still very indifferent to normal human interactions; such as Irene shown to be surprised after helping a child up and being thanked. This indifference is due to the fact that they were only trained to do what was necessary for them to survive, particularly fighting and feeding on human blood, and that being taught to live within humans was never the goal for their creation.

Apart from the fact that the Schiffs only goal is survival, the individuals composing them has a tendency to lean towards each other. They are shown to be very cooperative and often talk before planning to do something, such as the tracking of Saya and Haji. This willingness to do everything together can be traced from the very lab they were experimented on, since they needed each other to survive when they were given chiropterans to kill, and when they escaped the lab together in search for hope that the humans around them talked about.

Abilities/ Defects
Like chevaliers and chiropterans, the Schiff have enhanced speed and strength, and must drink blood to survive. However they are different in two key ways: sunlight will burn them to death, and they form a condition they call "Thorn" that causes them to slowly crystallize. It initially manifests itself as red cracks that usually appear on the neck, spreading along the body until the afflicted Schiff shatters completely.

The Schiffs also seem to have the capability to wander around during day time; considering that it is a gloomy day and the sun is not out. This is shown when Irene freely wanders around Paris, but gets weakened when the sun starts coming out.

Plot
Slaves at first, the ten Schiff decided they wanted to be free and escaped from the lab where they were created, killing most of the humans there.

Due to the parting words of one the scientists from the lab, they believed that they were created from Saya's blood, and so her blood would save them from their destined short life spans. They attack Saya and Hagi, but when one of the Schiff, Ghee, drinks Hagi's blood, it kills him almost instantly. They later try again with Saya's blood, but it also causes the Schiff, Irene, who drinks it to die instantly. They realize that the scientist lied and that it is Diva's blood they require to live, not Saya's and devote themselves to hunting Diva down. But they die one by one and the only living Schiff until the end of the anime is Lulu.
