Characters
Eves
He's 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 left in the care of his ever-busy uncle. As a result, Mahiru grew up mostly alone and has developed many talents for household chores. 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 black 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 is what may represent him the most due to Mahiru's personality, and that it was the first thing he used to hit Kuro with when they met. His Lead later changes into a Spear, giving Mahiru more physical prowess. Mahiru's catchphrase is "Thinking simply, it's got to be me!"
Lily's Eve, he's a high school student who is in the same year as Mahiru. Misono comes from a very wealthy family and unfortunately possesses a very weak physical composition, which causes him to be easily exhausted. He has a tendency to look down on others such as when he commanded Mahiru to work for him in stopping Tsubaki. It's possible that this may be due to a lack of social skills. He is a child born from the affair between his father and Mikuni's home tutor. Out of jealousy, his real mother was killed by his father's wife with Doubt Doubt's help. She spared Misono and decided to raise him as her own son. While growing up, he witnessed his older brother Mikuni kill their mother but could not remember it fully because his memory was altered by Lily. He resented his brother for leaving the house until he learns the truth. Misono's Lead is a chair which he often sits in to rest, and has so far shown creative uses for said chair in combat.
Jeje's Eve, he's Misono's older brother and an antique dealer. He puts on a childish personality, however his true personality is quite the opposite; he is cunning, shown to be quite manipulative and doesn't have a second thought killing Subclass. Misono resented him for killing their mother and for running away and taking Doubt Doubt with him. It is later revealed that Mikuni and Misono are actually half-brothers. Mikuni accepted the result of his father's affair but despised his father all the same. When Doubt Doubt's power took a toll on his mother's sanity, Mikuni killed her to keep her from killing Misono. Then he left home, taking Doubt Doubt with him. He is a former member of C3. During the battle at C3 headquarter, Mikuni is revealed to be working together with Tsubaki's group for yet unknown agenda. His Lead is a rope that takes the form of a noose, which he uses to strangle people to death. He is, so far, the only Eve to have a Lead that specialises in killing his opponents.
Old Child's Eve, he's a junior high school student who works in an onsen. He tends to be very soft-spoken and simple-minded. Despite being a junior-high student, Tetsu has a tall and big stature, and people often mistake him for a college student. Tetsu doesn't seem to care at all that he's associated with vampires, shown by how he often carries around his Lead (in his case, a giant indestructible coffin) which he even uses to advertise for his family's Onsen, since he doesn't know how to get rid of it. His contract with Hugh has recently come under speculation as it was revealed that he is not the one who chose the name "Hugh", with a necessary part of the contract being that the Eve chooses the new name; and it is possible that Hugh has been working with Tsubaki, much to the shock of Tetsu.
Lawless's Eve, he's a world-known Austrian pianist. Licht's personality can only be described as bizarre; he seems to consider himself an Angel, and even strikes poses while wearing a white backpack with wings attached. It's rare to see him smile; he almost always scowls. Licht has a violent streak, often brutally attacking other vampires (which he labels "Demons"). Licht also has an intense hatred for Lawless in particular, who he often calls a "rotten hedgehog" and is prone to tormenting or attacking. Licht possesses two Leads: A pair of powerful boots which can slow the regeneration abilities of vampires he kicks with, and a Grand Piano which he can play various songs on, with often debilitating effects on those who listen to them.
An engineer for C3 who has become the new Eve for the Servamp of Wrath, The Mother, who she named "Freya". She is a childhood friend of Shuhei whom she nicknames "Loki". She joined C3 together with him after the death of his father to make sure his vengeance won't be fulfilled as she doesn't want him to become a murderer. Unlike Shuhei, Izuna believes that humans and vampires can coexist, preferring to settle things peacefully rather than by brute force. This make her regretting ever making weapons that have been used by C3 to kill countless vampires. During her contract with The Mother, their contract item is Izuna's hair.
The current Eve of World End, the Servamp of Gluttony, who he named "Ildio". Niccolo is the boss of the Carpediem mafia family, succeeding after his father. Despite his position as the boss, Niccolo is rather spineless and lacks self-confidence, easily getting scared or pressured by people around him, but is still trying his best to live up to his position as the boss of Carpediem family. He cares for his subordinates and his Servamp, and wouldn't stand quiet if somebody hurt them. He is constantly saddened by the fact that World End seemingly never cares for him and his previous Eves whose names he never bothered to remember.
Servamps
The Servamp, or servant vampire, of Sloth. The name given to him by Mahiru as part of their Servamp contract is , due to the color of his cat form's fur. Kuro is the oldest of the eight Servamp siblings and, according to Mikuni, arguably the most powerful of them. This is contrary to Kuro's lazy personality, and he can often be found dozing off, playing video games, or eating junk food in Mahiru's apartment. So far, he is the only Servamp without any Subclass, because he doesn't know whether a person wants to live longer or not and has so decided to have none. 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 ended up regretting his action. The 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: the first being his usual black cat form, and the second being a giant lion form. Kuro's primary weapons are a pair of deadly, razor-sharp claws that can easily skewer targets.
The vampire of Melancholy. This mysterious man introduces himself as the eighth Servamp and the youngest sibling, despite the fact that there are only supposed to be seven. Tsubaki has a psychotic and unstable personality, which is evident through his stated desire to "kill everyone who doesn't know him". His motives and past are currently unclear, but he has a close relation with the person who created Servamps, referring I'm as "Teacher". However, Tsubaki genuinely cares for each of his Subclasses and won't ever betray them. Tsubaki commanded a sizable force of Subclass vampires until Lawless of Greed massacred almost all of them during their attempt to kill his Eve during a piano recital. His animal form is a silver fox. His primary weapon is a Katana.
The Servamp of Lust, and bound by contract under the name Snow Lily (or simply Lily) to Misono Alicein. He is the second youngest of the eight known Servamps, and has a tendency to strip no matter the occasion. For generations he has served the Misono family alongside Doubt Doubt, the Servamp of Envy. After Mikuni killed his mother to protect Misono seven years before, Lily manipulated Misono's memory so he won't remember the reason behind Mikuni's banishment from the house out of fear that Misono would reject him for being the representation of lust. When Misono finds out about Lily's manipulation without knowing the truth, the bond between him and Misono becomes strained for a moment, giving Otogiri the opportunity to destroy his pocket watch that was also the source of his power, greatly weakening him. Since then, Lily is mostly bedridden and lost his tendency to strip as his body becomes weaker until he reverts into a baby. His animal form is a butterfly. His primary weapon is a conjured Scythe that can cut the "spirits" of its victims, rendering them unconscious.
The Servamp of Envy, and bound by contract under the name to Mikuni Alicein. Jeje is the third eldest Servamp, and possesses a quiet personality. He rarely speaks and often mumbles when he does. He is also quite gullible, believing every time Mikuni promises to give him his blood in exchange Jeje doing as he told him to, only for Mikuni to pretend not remembering the promise. Jeje used to serve Mikuni's mother and has been protecting the Alicein family together with Lily for generations. However, seven years before the start of the story, Jeje's power started to corrupt Mikuni's mother, leading her to kill Misono's mother. Jeje erased any evidence of the murder. She eventually tried to kill Misono himself but the attempt was stopped by Mikuni who killed his mother and took Jeje with him when he left the house. His animal form is a snake. Jeje's primary weapons are a pair of conjured fully automatic guns that are mostly hidden underneath his massive sleeves.
