Ravel Phenex/Relationships

Issei Hyodo
Ravel started to admire Issei after he defeated her brother Riser to get back Rias. She started to develop feelings for him in Volume 5 and fell in love with him in later novels. Ravel officially became a member of Issei's harem in Volume 12 and is now fighting all the other girls that are interested in Issei. Ravel's reactions to Issei's death shows that she is in love with him and now is a rival to the other girls.
