Rei doesn't seem to have any hostility towards Shiho unlike other Black Organization members. He attempted to capture the person he thought was her alive instead of trying to kill her, regretting he might have to resort to violence to do so. Rei says he had met Elena and Atsushi Miyano while they were alive. Rei does not know Shiho is Ai. During a car chase in Detectives' Nocturne, Shiho gets a strong feeling that member of the Black Organization was behind her, but she doesn't seem to pinpoint it to Rei's pursuing Mazda FD RX-7.
