Review Detail of Empyrium in Conquering the Universe with my Sister

Writing quality: Very good, nearly perfect, I can't complain Story development: Great start of the story, a lot of potential Character design: I love the siblings, the side characters are good too, hope they won't be forgotten Update stability: 6 chapters a week is really good World background: We don't know much but the start is already great I wonder what is the different between Elves and Angels?
