Servamps have complete immortality as there are no known ways to kill them, yet they are not without any weaknesses. Though these weaknesses won't kill them, it's able to momentarily weaken them. So far the known weaknesses are:

They automatically changes into their animal forms if exposed to sunlight. They can change back to their human form and fight during daytime if they drink their Eve's blood, but not as strong as during nighttime. They can't swim in flowing water. They'll collapse if they touch holy water for a few seconds, even if it's just a tiny drop. As stated before, if their contract item is destroyed, they'll lose their Djinn and power (and potentially die over time). Servamps have an ability to change a human into a vampire by making a dying human drink their blood. This vampire is called a Subclass. Similarly to how a Servamp is bound to obey their Eve, a subclass is bound to obey the Servamp who changed them.

All servamps were originally normal humans who died and then resurrected into vampires. The exact method to create a servamp is not yet revealed. However, according to both Sleepy Ash and Lawless, it's not easy to perform the method. Other than the creator of servamps, people who tried the method ended up with a disastrous result. The attempt would always brought a large scale of suspicious deaths throughout an entire region. No matter what kind of different approaches were made, it always ended up with the practitioner and everyone else died. Even with remote supervision, surveillance records unnaturally vanished, and those who saw the records disappeared as well, including the result itself. For this reason, the method is deduced to be a domain that humans cannot venture into

Servamp is the combination of the terms Servant and Vampire, which means they are vampires meant to serve a master (human). There are four conditions for a human to make contract with a Servamp. The conditions are:

Gives the vampire a name. Gives the vampire a present. Calls the vampire with their given name when the vampire is in human form. Makes the vampire drink the blood of the human who has done the three conditions above. Once all four conditions above are fulfilled, the Servamp and their human master, called an Eve, will be connected by a chain that binds the Servamp's neck and the Eve's wrist or ankle. This chain will appear every time the Servamp drinks the Eve's blood. Once the contract is made, the Servamp can only drink the blood of their Eve and their power depends on how strong the will of the Eve flowing in the blood is. If the Eve's will is strong, then the Servamp will get a significant power up. If the Eve's will is weak, then the Servamp will only get weaker. Servamp's dispositions completely change depending on who they contract with, including their reasons for fighting. Servamp's are obliged to listen to their Eve's order, though there are times they can refuse to follow the order even if the Eve forced them.

Servamps, short for servant vampires, are said to be the first original vampire siblings to exist in the world. However, as the story progresses, it's revealed that the Servamps didn't just come into existence, but were rather humans changed into immortal vampires by a certain human hundreds of years ago. There are supposedly only seven Servamps in existence who each represent the seven deadly sins, but it's later revealed that there's the eighth Servamp who even the other Servamps didn't know existed. All of the Servamps have street names and given names, and some also have nicknames. These names were most likely given by the Creator of the Servamps. When they are not serving someone, they are usually referred to by their street name or the sin they represent. All Servamps are able to change into animals. They usually change into their animal forms when exposed to sunlight, though they can freely switch between their human forms and animal forms at will.

looks: If Kuro is not in his cat form, he has shoulder-length, blue hair with his front bangs reaching his eyes. His eye color is red and he has big, dark bags under them. They are always half-lidded and express a feeling of boredom. Just like any other vampire, he has pointed teeth.

Kuro mostly wears a blue jacket which is a tad darker than his hair color with the hood pulled over his head, the black fur looking close to the one of his cat form. He also has a patch on his left shoulder with the Roman numeral for 1, probably because he is the oldest of the eight Servamps. He wears the bell Mahiru gave him as their contract symbol around his neck as sometimes seen in official illustrations, which is apart from that mostly hidden under his clothes. His blue jacket is often buttoned open, either a simple black or white shirt hiding under it. On both sides, Kuro has chest pockets. The hem of his jacket splits into many threads, starting short at the front but grow in length as they reach his back. His white pants are skin-tight and held up with a red belt, which is rarely seen. Kuro wears long, black boots that almost reach his knees personality: Being the Servamp of Sloth, Kuro spends his time sleeping, lazing around or playing video games. He feels no shame in running away to avoid any trouble and refuses to make decisions, since he doesn't want anything to be his fault, and doesn't want to disappoint anyone. Kuro is a 'shut in' pacifist vampire, and rarely drinks Mahiru's blood, most of the time he refuses and drinks only when he is about to fight. He prefers staying at home rather than going out and seems to dislike the changes of temperature, according to him vampires are delicate to this.
