Rosario+Vampire: Prototype

Moka Akashiya

赤夜萌香

Moka Akashiya (赤夜 萌香, Akashiya Moka) is the main heroine. She is a Vampiress in Yōkai Academy and the first person Tsukune Aono meets when he sets foot in the Yōkai realm. Moka takes a liking to Tsukune, initially because of the taste of his blood (something she very quickly becomes addicted to), but later when he tries to protect her from the Outcast Ayashi, Saizou Komiya. When the Rosario Cross around her neck is removed, the seal keeping her inner nature is released. Cold and arrogant, the Inner Moka is a completely different entity from the kind and loving Moka, going so far as to specifically remind Tsukune to "be kind to the other Moka". Tsukune is the only one able to remove the Rosario Cross around Moka's neck.
