where they are unable to stop it and has to adapt and accept it just like the sea where it is constantly moving and not always calm.
The four characters who are dear friends to them and loved each other doesn't want to change and stay as it forever just like a calm sea but it is not going to happen, changes is going to happen to make them grow, once they accept it as a force of nature the sea will begin to move again and once sea is move again it is not seen as scary it seen as something beautiful.
The art style, the ocean blue theme of this show its one of the best looking anime out there having the classics PA Works looks which I loved it.PA Works really love details, this show is full of details you can see the grunges, wear and tears on the environments in the show, which shows how detailed and tailored to make the world believable.
Finally I really recommend the show, It is worth your time take it slowly and enjoy the show.
