Not sure if it is part of the side story or epilogue. But Remilia will meet Emi's soul and ask her if she would like to be reborn as Remilia and Angel daughter. However she won't have the memories of her previous life
in our world or the memories as a reincarnater. She will be completely reborn a new person. Emi was aware what Remilia was doing, and although she is a good person. She did not forget the hurt and betrayal she had suffered. And therefore does not condemn Remilia for her actions. She agreed and was reborn as Remilia and Angel's daughter. So yes they, kind of, meet physically this way but slightly different?
i love Remilia so much, I hope there's a way for her and Emi to reunite physically and not just through Remilia's devotion and faith for her.
