Seraphina

Succubus, Seraphina just turned 18 years old and must start doing her demonic duties or be outcast in the demon world. To hide her succubus allure during the day, she wears glasses and wears overalls and nerdy clothes to find her prey. She ends up finding her first prey in 18-year-old, Benjamin who is nerdy himself. She goes into his dreams and discovers he has a crush on a popular schoolgirl named Trish. She needs to intercept it in order to take over so she befriends him at school. What she thinks about humans, being weak and selfish and deserving of being used turns out to be not true in Benjamin as he shows her nothing but kindness and selflessness. She decides against him being her first prey but her mother says she has already marked him and must go through with the ritual or else lose her succubus powers forever and be outcast.
