A Gift From God

14 year old Andria Tania and her Math teacher, Sebastian Harris were like best friends. Sebastian would go to Andria's house to teach her extra Math and they would also play together or hang out if both of them were free.
But then one day, Andria and Sebastian began to have seizures before they were turned into hybrid half human half snake monsters exactly like Medusa, this was when two evil Goddesses, Zeus and Echidna were cursing them and they needed to use the power that they had in their new bodies in order to fight those Goddesses.
