Datenshi Gakuen Debipara is at heart a spoof which makes fun of certain aspects found in manga/anime, as well as the Shin Megami Tensei franchise. It's a short ten-chapter, one volume series which reads rather quickly, so time-wise it can easily be done in one sitting.

Story: 6
It's silly, but it's a spoof; if a serious, original story is what you're hoping for, you'll be highly disappointed in that regard. It's a mesh-mash of lots of typical shounen story and character ideas all rolled up into one very corny, but often ridiculously funny story whose setting and basic storyline could easily have been for a Shin Megami Tensei game.

It's good. Not amazing, but worth being considered above average in my opinion.

Character: 8
The manga is full of stereotypes, being the spoof it is. It works well with the whole atmosphere of the story, though. The short length also helps, since some of the characters which come across as ridiculous are initially amusing and funny, but after a while they would have gotten extremely old and wearing on the reader had this series been much longer.

Enjoyment: 9
I enjoy reading something which can give me a good laugh, which is what this series did for me. At least half the chapters I laughed out loud at least once, and there were many more mental chuckles. While reading in one sitting is time-wise possible, I suggest if you find yourself after the first half beginning to tire of the characters, to take a break and return to finish it later. I personally found the middle the most lacking in humor for me, but the series as a whole has high enjoyment value for those of us who just need to laugh at something ridiculous.

Overall: 7
The main points of this manga is its silliness, which it does well in delivering. The story is corny, but given the fact that seriousness isn't what this manga aims for, it works just fine. Due to the awful silliness of the humor, if you're someone who's incapable of cracking a smile over the awful tackiness of movies such as Sharknado, this series may not be for you. If you're the kind of person who spends half the time laughing during such movies, this series will serve you well.

Is this a manga you'll want to reread? Probably not.
Is it worth reading that one time? Yes!
