this is my first review so sorry if there's a mistake.
POSSIBLY LITTLE SPOILER
Art-10
In my opinion this movie has an art of indulging eyes throughout the scene presented with a details view on the beach and ocean as well as subtle movements in animatio so, no complaints in this art style.
Music-10
as well as the music that accompanies the story during a sea diving scene or when a character experiences something magical in this story, a background sound that really matches all scenes. I give a 10/10 score on music.
Voice acting-8 (I hate the father, lol)
while for voice acting there are no problems. All actors match the characters being played. except for one, the main character's father who will later be explained below.
Character-7 (Is because side characters)
all three protagonists have different personalities who are friends. The main character is said to have mischievous behavior that often acts at will and also she hates her mother, for some reason is not told why she hates her mother in the movie, even so throughout the story, we will see the development of this girl who will change throughout the story. While the other two protagonists are cheerful children who accompany the main character. This movie taught me about what friendship is and why it is valuable. That's what makes me like these three characters, because they help each other and get through the fun and sadness together. Oh yeah, I forgot to tell you about the main character's father who was very bland, he didn't have the characteristics in this story as well his voice acting, for example when his daughter wanted to go to the beach during a storm he was the only one who didn't panic while the mother who does not look useful is only showed her feelings, unfortunately, this father has an empty role until the end of the movie, applause for the mother.
while for supporting characters such as the teenager and weird grandmother, their origins are not conveyed and why they are involved in the story so for supporting characters is very worse. While some other institutions in the story that might look like a bad guys are also not told what they are planning.
Story-2
the story in this movie is very ordinary and even confusing, in the beginning to the middle I enjoyed the story, until the end of the story will be a common thing for most anime in general. I can not tell because of spoilers. Honestly, maybe the story in this film is too hasty so it does not explain the details of what happened.
Conclusion
maybe the art and ost in this movie is great but the story is meh.

People who only care about unique art style, hachi's fans, People who are bored during pandemic and have free time.
This anime is NOT suitable for you who are :
