Mahiru Shirota is a normal high-school student who likes something simple. One day, on his way back home, he found a black cat and decided to take care of him, naming him Kuro. However, the next day, he is surprised to find out that the black cat is in fact, one of the seven Vampire that represents Seven Deadly Sins, Sleepy Ash that represents Sloth and he will turn into cat when exposed to sunlight. From the moment Mahiru calls his given name in his human form and gives him a neck collar, Mahiru has formed a temporary contract with Sleepy Ash. Their contract is finalized once Sleepy Ash drinks his blood, making Sleepy Ash a vampire servant known as “Servamp” and Mahiru as his master called “Eve”. Following this, Mahiru and Sleepy Ash encounters Tsubaki, a vampire who claims to be the servamp of melancholy and the unknown eighth brother of Sleepy Ash and the other servamps. Tsubaki intends to wage an all out war against the seven servamps. Mahiru decides to gather the seven servamps to fight together against Tsubaki and his group.
Kuro “Sleepy Ash”
A servamp, or servant vampire, of Sloth. The name given to him by Mahiru as part of their Servamp contract is Kuro, due to the color of his cat form’s fur. Kuro is the eldest of the seven Servamp siblings and according to Mikuni, arguably the most powerful of them. This is contrary to Kuro’s lazy personality, as he often can be found dozing off, playing video games, or eating junk food in Mahiru’s house. So far, he is the only servamp without any subclass, because he doesn’t know whether the person want to live longer or not and decided not to have one. Kuro’s past is mired in mystery to Mahiru, as he is rarely ever willing to discuss it. The mere mention of his past was enough to make the usual lazy Kuro to become angered. It’s revealed that Kuro had a falling out with Lawless because he decided to kill the one who made them Vampires after receiving the request from C3. The reason for accepting the request is because he thinks that the world doesn’t need “monsters” like them anymore. Following the request, Sleepy Ash killed his own creator, but this haunted Kuro who then regretting his action. His regret and grief made Kuro decide to not do anything unless someone tells him to until Mahiru urges him to face his own mistake, which also significantly improves Kuro and Mahiru’s friendship. Kuro has two animal forms, first is his normal cat form and second is his giant lion form. Kuro’s primary weapons are a pair of deadly, razor-sharp claws that can easily skewer targets
A Freshman High School student who lost his mother to an accident at a young age. Having no father to take care of him, he was then left in the care of his ever-busy uncle. Thanks to this, Mahiru grew up mostly alone and has developed many talents for household chores because of his time alone. Mahiru’s talent for housework has also extended into his school life where he often uses them for class projects and the like. After discovering Sleepy Ash as a cat and eventually becoming his Eve, he obtains a Lead (essentially a conjured tool for Eves) in the form of a Broomstick. Kuro later notes in irony that it’s what may represent him the most due to Mahiru’s personality, and that it was the first thing that he used to hit Kuro with when they met. However, his Lead later changes form into a Spear, giving Mahiru more physical prowess. Mahiru’s catchphrase is “Thinking simply, it’s got to be me!”
