User blog comment:Lias' Pawn/Issei's possible further Harem members/@comment-108.224.166.119-20150129030230

did everyone forget that sona's rook, tsubasa yura I think is her name, has a crush on issei but she hasn't confessed to him because she's afraid of rias and akeno. I can definitely see her maybe joining the harem some point in the future.
