I will keep this review short and easy for people who plan to watch this.
A man who has the choice to become a king of gods, king of demons or to just stay a man. This is what the whole anime revolves around.
It's a regular harem with a bit less regular characters. It is playful but has some more serious moments.
You will probably have read the synopsis which makes for a good picture of what the anime is about.
The anime comes to a somewhat solid conclusion, this, however, is a point of discussion.
Overall it's a pretty fun anime to watch, so I gave it an 8!
