It's a very short, but very interesting story. It's possible to read aprox. by 30 minutes, but it really enjoyable. The story is telling about the girl who met an angel called Seraph and about their conversation. Also there is some lesbian subtext.(I have no any problems with lesbians or lgbtq+ community). After the reading, I had feeling that something is untelling, but I think It was done with purpose. During the reading single volume, I could felt different type of feelings: sadness,hapiness,perplexity etc. The ending is very ambiguous I think , it does not have a good ending, or a bad ending, it has nothingat all. We have only scene where Seraph and Lucifer is gone away in space and MC is continuing her ordinary life route.

Despite this, my rating is 9, I can fully recommend this manga for you to read if you like unusual things, especially since this story will not take you long.
