Insane Deities or a Really Creative Author
Imagine if you will a life where the various gods and deities walked around with us. Were bitchy customers and smites us if they were wronged. That or felt wronged. Most were not really wronged. However, they felt like they were so they made sure that the world around them did as well. However, this makes for hilarious entertainment... when you just watch it. Then again, maybe the person who is insane is the author.
Leave it to a manga author to come up with the most insane plots and scenarios on the planet. I mean how can you go wrong when you stop a Typhoon by calling the deity in charge of it and telling it you are missing a huge online event. That is awesome, now I just need to learn to manipulate said god. That way I may crush my enemies. Well or just cause some mayhem for my own personal amusement.
If anything this anime is good for a quick and easy laugh. The anime itself makes little sense. Most of the time ending with some kind of sentimental note. However, getting to that point can be hilarious. Especially when it comes to Mayu borrowing things.
