Yet one day, out of pride, he accidentally accepts what he assumes to be a challenge for a Bishōjo game when in reality he has accepted a contract from a bumbling demoness name Elsea de Lute Irma, also known as Elsie who asks for his help in capturing runaway spirits from Hell who are hiding in hearts of girls. The only way to force the spirits out of the girls hearts is by making the girls fall in love with him, much to his horror. With the threat of death for both of them should he refuse, Keima has no choice but to help Elsie. Together with his intelligence and knowledge of the dating sim genre and Elsie magical powers, Keima is about to embark his greatest challenge yet.
