***This review may contain a little spoiler If you are not the type of person who enjoys harem, romance, characters who only know how to burden others, nor the beautiful side of religion, this anime is a must try! This is a very rare type of anime with its interesting and impressive plot. It bluntly reviles the dark side of religion. This anime might make Christians feel uncomfortable watching it since it might make you doubt the existence of God. I love how this anime makes almost every miracle happens in the story solved by scientific reasons. Honestly, it makes me feel smarter after watching it. Theonly flaw in this anime is it's ended too soon without reviling the real ending. It still can go a long way with its storyline. There are still many things need the answer but it just ended without answering them. I hope it will have a second season. Sadly, it seems to be low-rated and not as popular as it deserves, so it probably won't be any more season. I hope it will tho.
