Assassins Pride is a Japanese fantasy light novel series written by Kei Amagi and illustrated by Nino Ninomoto. Humanity has been brought to the edge of extinction and now exists solely in the last remaining city-state of Flandore, where individual city blocks are housed in separate glass domes. Travel between the domes is possible only via train lines running through glass tunnels. The world outside the domes has become one of eternal darkness and is completely infested with savage lycanthropes. Within the domes, humanity is divided into the nobility and the commoner classes. Through their blood, members of noble families are able to manifest mana which grants them powerful superhuman abilities enabling them to fight and kill lycanthropes. Melida Angel was born to a noble father and a commoner mother but has never manifested mana and attends an elite academy to hone her skills with mana. On orders from Melida's noble grandfather, Lord Mordrew, the assassin Kufa Vampir is ordered to become Melida's tutor and discover if Melida is a true member of the noble Angel family. If Kufa discovers Melida is the product of her mother's affair with another commoner and not blood related to Lord Mordrew he is ordered to assassinate her. Kufa confirms Melida is likely not a noble but decides he cannot ignore her strong spirit and offers her a way to manifest her mana. With Melida able to use mana for the first time Kufa must keep his actions a secret from Melida's family and from his guild, White Knight, or both he and Melida will be executed.
