Amanchu! is the story of a teenager called Futaba. She looks like a supermodel but she suffers from social anxiety. Futaba recently moved to a seaside town and there, she quickly befriends an apparently mentally handicapped girl who goes by the nickname of Pikari who, throughout the series, teaches the protagonist that the secret to a happy life is to stop stressing about stuff and enjoy the little everyday things. The series clearly wants to get the message across that regardless of the fact that someone might look utterly braindead to you, you still might be able to learn quite a bit from that person andthey might impact your life in a positive way. So be nice to weird people and try to get to know them!

The rest of the characters in the show are quite forgettable because the series focuses mostly on the relationship between the Pikari and Futaba and forgets to develop the supporting cast, which is a shame because their teacher had the potential to become a very interesting character.

Amanchu!'s color palette is quite soft and soothing and it fits the series very well. I loved the way this show looks because of it.

Also, there is quite a bit of diving in this series.
