servamp female mahiru

Mei Shirota is a normal high school student who likes simple things. One day, on her way back home, she finds a black cat and decides to take care of it, naming it Kuro. The next day, however, she is surprised to find out that the black cat is, in fact, one of the eleven vampires that represent the eleven Deadly Sins. His name is Sleepy Ash, he represents Sloth, and he turns into a cat when exposed to sunlight. By giving Sleepy Ash a name and a cat bell, and then calling him by his given name, Mei accidentally forms a temporary contract with him. The contract is finalized once Sleepy Ash drinks her blood, making him Mei's vampire servant known as "Servamp" and Mei becomes his master called "Eve". Following this, Mei and Sleepy Ash, now Kuro, encounter Tsubaki, a vampire who claims to be the Servamp of Melancholy and the unknown twelve brother of the other Servamps. Tsubaki intends to wage an all-out war against his nine brothers and two Sisters, while Mei decides to gather them to fight against Tsubaki and his group together.
