is a teenage boy who enrolls in Yokai Academy without realizing that it is a school for monsters. He meets Moka Akashiya, a vampire who takes an interest in him because of the sweet taste of his blood (a running gag in the series involves her catching Tsukune off-guard and biting him on the neck). Fearful for his life and ready to leave the school, it is only his affection for Moka that motivates him to continue attending Yokai Academy. Though he has no special powers of his own, he constantly risks his life to protect his friends. Later on, he acquires vampiric abilities, then ghoul-based powers (the latter of which puts his humanity in jeopardy), allowing him to fight toe-to-toe with almost any supernatural foe.

Though ordinary and often cowardly in the beginning, Tsukune is willing to protect his friends without second thought, which earns him many new companions, most of whom are girls who compete for his affection. He is both gentle and understanding, and displays great courage when his friends are threatened. Later in the series, Tsukune is infused with Moka's blood which enhances his fighting abilities and strength. At first, Moka feels responsible for this, but Tsukune says that he doesn't blame her for his transformation. When it is revealed the blood he gained from Moka was Shinso blood, Tsukune undergoes training to master his monster energy to use new techniques that will help him fight. Also, Ruby sensed there was something dark inside him after his rematch with Kuyo.

The title character is a vampire first-year student at Yokai Academy. Exceptionally sweet and kind, Moka befriends Tsukune after ingesting his blood, and becomes addicted to its taste. She wears a rosario around her neck; however, when it is removed, she becomes , which is a cold, arrogant and skilled martial artist. Tsukune apparently is the only person who can remove her rosario. As her outer nature is completely oblivious, Moka reminds Tsukune to "be kind to the other Moka", and that the Outer Moka that loves Tsukune is a fake personality. Later in the series, Moka lends some of her vampire blood to Tsukune, which enables him to possess some monster powers.
