New character in volume 3 of Hentai_Ouji_to_Warawanai_Neko, エマヌエーラ・ポルラローラ (Emanuela Porelora) aka エミ (Emi). The above is cover art for volume 3.
The name is meant to be Italian. I considered breaking the last name into 2 parts (Por Relora) or using a double consonant (Porrelora) to better approximate the Japanese but I'm not sure what would be authentic here.
