I Got a Girlfriend!.Issei Hyodo is a high school student who is unpopular with girls at Kuoh Academy. One day, Rias Gremory, the crimson-red haired top idol of the academy and president of the Occult Research Club, discovers Issei and asks her vice-president Akeno Himejima about his identity. As Issei dreams of having a girlfriend, another girl named Yuuma Amano shyly asks Issei out, to his excitement. At the end of their first date, Yuma asks Issei to die for her sake and reveals herself as Raynare, a fallen angel. After Raynare kills Issei, he sees a vision of Rias. Assuming the incident to be a dream, he resumes his normal life. However, when Issei encounters another fallen angel, Dohnaseek, he is wounded. Just as Dohnaseek is about to finish off Issei, Rias intervenes and saves him. The next morning, Issei discovers he and Rias are naked together in his bedroom. Reassuring that the dreams were real, Rias introduces herself as a devil and his new master.
