Yoku Wakaru Mahouka!

The Irregular at Magic High School is a bit tough to follow and understand for the average viewer. It's a very scientific anime, which I love, and even a sciency person such as myself had to watch it a couple of times to get a full understanding of the science and magic behind the series. This ONA is a great watch to get a head start on the show before watching it. I'd say it's almost essential to watch. The best part is it's short and sweet and to the point and the chibi characters are pretty cute and gives the main characters a quick ... introduction.

This ONA consists of 6 short chibi animations about the anime: "The Irregular at magic high school" and explains some of the concepts in the anime. The animation with chibi characters is plain bad and there are only two reasons to watch this as far as I can tell.

The most important reason you would watch this ONA is to understand concepts from the anime since they're explained a bit better here. If you're just watching to understand a certain part of the anime then you don't have to watch any of the other episodes since there's no storyline. The episodes explain the following ... concepts:
1. Magic High school
2. Magic
3. Magicians
4. The Nine schools competition
5. Spirit magic/ancient magic
6. The thesis competition
There's also a 7th episode about the powers of Tatsuya which is listed as a sequel to this ONA.

The other reason to watch this ONA would be because you like the characters and their interactions and want to see more of them. The interactions are a bit watered down but every topic is presented by different characters and could be fun to watch if you really like them.

Overall this is an okay ONA because it bothers explaining concepts from the anime. However it is not something worth watching unless you want to know about some of the concepts or really like the characters from the anime.

Honestly what are these ONA's? These are so pointless that I decided I'd watch it once for one of my favorite anime and I was left thinking "What the hell is this?" This is useless information that the audience honestly does't need to know to watch and enjoy the anime, Mahouka Koukou no Rettousei yet they decide to spend money and create this useless thing. Not one, Not two, Not three, Not four, Not five, But 6 friggin episodes of it. Completely useless and boring, don't watch it.
