Ruka Azumi's ordinary summer vacation revolves around spending all her time on the handball court to avoid her only housemate, her alcoholic mother. When an incident at practice leads to Ruka's exclusion from the handball team, she is forced to find other outlets to enjoy herself, eventually winding up at the aquarium where her father works. There, she meets Umi, a mysterious boy raised by dugongs who is being kept at the aquarium in order to research his strange water-dependent body.

Ruka and Umi become fast friends, and the pair is soon joined by Sora, Umi's brother who also has an unusual relationship with the ocean. Together, the trio explore a dazzling undersea world while learning about a peculiar "festival" that all sea creatures around the world are preparing for.

Ending Theme

Breathtaking and seamless animation. I'm glad they translated Igarashi Daisuke's art to the big screen pretty well. The art and the soundtrack is absolutely beautiful and I'm also a sucker for animes with the ocean/summer days/ fantasy aesthetic themes (reminded me of the anime Nagi no Asukara). Seeing it on the big screen gave me that same chest expanding feeling whenever I see amazing animation alongside moving soundtracks.

Honestly, the storyline lost me a little bit but I'm not gonna say I wasn't entertained and absorbed. I would still highly recommend for the imagery. Can't wait until it is released in English to rewatch it!

Mixed Feelings
Let me tell you first off, tokyo movie theaters are not cheap!!! $20 for a ticket are you insane?! I'd better be getting my money's worth if I'm paying that much. Like this movie better change my life.

Next I want to let you know that I've never read the source, or heard of this title before watching this movie. So this review is my impression of the movie watching it blind.

It actually started off really great in my opinion. The premise of a boy who was raised in the wild is not something entirely new but still very interesting. And it ...

For those that are curious, this is an animated adaption from the manga with the same name, beautifully illustrated by Igarashi Daisuke. For starters, I think the film was definitely ambitious, but in honesty was all round lacking in a sense that the director could not successfully portray the clarity within the material of the original work.

STORY: (7/10) Five whole volumes of plot, filled with existentialistic concepts combining science fiction and supernatural themes, delicate portrayals of the relationship between the characters and the panoramas of sea life- all of these are condensed into a mere 111 minutes, a little less than two hours. Nevertheless, ...
