Problem Children Are Coming From Another World, Aren't They? (which is known as Mondaiji-tachi ga Isekai Kara Kuru So Desu yo? in Japan) is based on a light novel series written by Taro Tatsunoko and illustrated by Yu Amano.

There are three main characters focused on in the series: Izayoi Sakamaki, Asuka Kudou, and You Kasukabe. Izayoi is an arrogant and bored teenager who usually tries to solve problems with violence. Asuka is a wealthy young woman who has an ability to command others with her words. You is a quiet girl who has an ability to talk to animals; she is often accompanied by a calico cat.

One day, all three of the characters receive an invitation to another world known as "Little Garden." When they arrive in "Little Garden," they discover that they were invited there a rabbit-eared girl named Black Rabbit. Black Rabbit tries to be serious, but can get flustered rather easily. Black Rabbit also has a power of her own.

Black Rabbit has summoned them there to help her participate in the Gift Games. The Gift Games challenge the participants with games of varying danger in exchange for rewards. By the end of the first episode, Izayoi fights in a Gift Game against a water god.

By the time I finished watching the first episode of Problem Children Are Coming From Another World, Aren't They?, I thought the series had an interesting premise. However, I'm really not in a rush to watch more of the series immediately. It's not that this is a bad series by any stretch of the imagination, it's just that by the end of the first episode, I didn't find myself completely invested in the characters or the story. Hopefully the potential that I saw during the first episode will continue to manifest itself as the series progresses.

The animation in this series is actually rather decent. While it may not be innovative or breathtaking, the animation looked as if the animators were putting effort into what they're doing. I thought the backgrounds looked particularly nice.

Content-wise, there was only a minimal amount of "fanservice" in the first episode, and I didn't see any blood or major violence. Personally, I would recommend Problem Children Are Coming From Another World, Aren't They? to anime viewers who are 14 or 15 years of age and older.
