Seiji is her adoptive father. Her biological parents aren't known. Her mother died giving birth to her that's about all we know about her biological parents. Richter handed her to Seiji after transplanting Cordelia's heart into her body as an infant. If there is a third season, hopefully he makes an appearance. We at least heard his voice this season.
