Amagi Brilliant Park has the same Author as Full Metal Panic, and it seems he put Amagi on hiatus to work on the more popular FMP. (no new volumes in three years, as I'm writing this)

Story: An amusement park has money problems, and they turn to a random high school student for help. Why a high-schooler? The owner and manager that needs help to save the park are both teenage girls, soooo... Ah, and almost the entire staff is actually from a fantasy world. It's easy to forget that, so be careful.

That's the general story, and it's not that bad. The problem is, with there being magic and creatures that are literally from a "fantasy world", they somehow fail to make any profit while running a Fantasy Theme Park. HOW!? This is a comedy story, do not expect romance, action or even anything interesting to happen.

Characters: *sigh* A Tsundere with big tits, a kind loli in a cute white dress, and a perverted Sheep know as Macaron. The "human" characters are all your standard types, nothing to say here. But this fantasy novel series excels at, surprise surprise, fantasy characters. The Sheep Macaron being a good example of how to make funny, adorable, and deeply disturbing mascots that make you laugh till you cry. Unfortunately, most characters are those boring looks-like-humans-but-are-actually-not-human characters. I disliked Full Metal Panic due to bad characters, so Amagi Brilliant Park managed to improve there, even if just a little bit.

Overall, this is a comedy. Don't take the fantasy stuff too seriously, just enjoy the silliness for what it is. There's a lot of management talk, and that is just not something I can connect with comedy. Some people probably will find it entertaining, though. Just not me.

I really liked the Anime, why did I not like the novels? Just like Outbreak Company (fantasy-comedy about company management), the Anime is so funny due to the voices and animations, and the book are slow and boring. Unfortunately, I shall not continue reading this, unfinished, tale of a failing amusement park. Luckily the anime has a satisfying ending.
