In both anime, the male character get involved with a god. The goddesses, Holo and Nagi, have similar personalities and often speak in similar manners.
Both are very similar in story. The main character wants to unite/change the world by fighting against those in control. The two stories also use mecha, which get more powerful as the story progresses.
The main characters in both encounter a supernatural being which they become very close with. Both stories are easygoing and relatively peaceful to watch. Each show beautifully incorporates music at the right times to set the mood of the story.
