The main protagonist, Luke Rutherford is a student who is nearing graduation when he meets his godfather, Rupert Galvin who informs Luke that he (Luke) is a descendant of Abraham Van Helsing and it is his destiny to save the world from demons. Luke is reluctant to fight the demons but does so anyway, feeling that it is his duty though he often complains that he would rather be attending social functions with his friends. Luke appears to have a nihilistic outlook on life but cares greatly about his best friend Ruby though he sometimes appears indifferent toward her.
