The story revolves around Mina Ţepeş, princess-ruler of all vampires, and her "protector," Akira. Like other vampires, Mina has been in hiding with her people for many years. Seeking to end centuries of isolation, Mina gains permission to create a special district for vampires, "The Bund", off the coast of Japan by paying off the national debt of the Japanese government. Mina then reveals to the world the existence of vampires and her desire for both races to live together. Tensions, however, run high as fearful humans and extremist vampire factions begin to interfere with Mina’s wish for peace with the human world.
The female protagonist and the current ruler of the Vampire world. She usually appears in a young and prepubescent state, though she is not shy enough to feel embarrassed when naked. Mina can act aggressive, cocky, and naughty. However, she actually feels vulnerable and lonely. She cares very much for the welfare of her people and does everything in her power to protect and preserve her species. Mina sympathizes towards the Fangless, creating a city underneath the Bund where they can live freely and without persecution. It is revealed that she has been in love with Akira since first meeting him, to the point her secret room is covered from floor to ceiling with nothing but pictures of him. Mina’s soul’s true form is an adult version of herself with wings. She wishes to have this form kept a secret, as that form’s body is able to give birth while her current one cannot, and because of that, she would be forced into marrying one of the Three Nobles, who are also "True Bloods" like her.
