Hello Guys, i would like to ask one question that bothered me a lot time now and when i found your blog i feel satisfied , here is my question In volume 19 Xenovia said to Issei that will follow him when become a  KING! but how is that possible? Xenovia is not part of Rias Gremory group as her servant?? how can be part of Issei's servants? i know that if you get one servant then is forever and even if this servant dies you can not replaced it as well.

Thanks for your time i'm looking forward for your answer. Arigatou Gozeimasu
