Main Characters[]
Issei Hyoudou[]
They first meet in Volume 21, where Issei was fascinated by Lavinia’s beauty which caused Issei to get a headache after she was smiling at him (due to his illness at the time). They meet again in Volume 24, Where Issei was enchanted by her singing voice, much to Rias’s dismay. Issei gain lecherous thoughts about Lavinia upon gazing on her large breasts, which causes Rias, Ravel, and Rossweisse to glare at him. Lavinia later showed Issei a notebook containing Vali’s words that she wanted to show to Vali’s rival and was happy that Issei was praising Vali.
