Finding a kindred soul is an amazing thing, especially when it’s a complete stranger. However, when Mahiru Kouzuki meets Kano, a former idol turned indie artist, they’re astonished to realize that they already share a connection, as a street mural of jellyfish, from which Kano draws constant inspiration, was painted by Mahiru years earlier, before she abandoned her dream of becoming an artist. Inspired, Kano convinces Mahiru to return to art and collaborate on a joint project, one that will combine not just their own shared skills, but also those of two more rather “different” and oddly connected young women in Jellyfish Can't Swim in the Night!

The characters have a clear connection to each other and their bond over art and music is something that brings them closer together.

The designs are artistic, creative, and engaging. An impressive design effort for the entire cast of characters. The leading characters feature especially impressive designs and these elements are essential to the production.
The animation is one of the best qualities of the series. Jellyfish Can’t Swim in the Night features quality art direction by Yūji Kaneko (Blue Spring Ride, Ranking of Kings). The art direction is excellent and has plenty of beauty.
The animation style is highly creative and engaging throughout. There is so much wonder to the art style. The animation is bold and the colors of the animation make quite the big impression. The color designs by Kei Ishiguro (Monthly Girls' Nozaki-kun, Sleepy Princess in the Demon Castle) add to these artistic qualities in the animation in spades.

Released on Blu-ray by Sentai Filmworks, Jellyfish Can't Swim in the Night is presented in 1080p MPEG-4 AVC encoded high- definition in the original television broadcast aspect ratio of 1.78:1 widescreen. The presentation is beautiful and there is so much to appreciate about the visuals. The animation features bold colors and vibrant artistry. The high-definition encoding is well-done and capably handles the series style.
One of the strengths of physical media is the quality encoding. Streaming video services tend to have more variables at play – such as internet connection speeds, data caps, streaming tier plans, and number of connected users. Even unexpected variables such as power outages or storms can occasionally interfere with a presentation. There is something dependable about physical media – knowing it's simply there for you.

The Blu-ray release includes a selection of lossless audio options: English DTS-HD Master Audio 2.0 and Japanese DTS-HD Master Audio 2.0 (with English subtitles). The sound effects by Hiromune Kurahashi (Ascendance of a Bookworm, FLCL: Shoegaze) are well- done on the release. The lossless audio is an impressive part of the presentation. The dynamics are well-done. Dialogue is clear and easy to understand. The score is a nice highlight of the release, too. English subtitles are impressive – free from egregious spelling or grammatical errors.
One cool thing about physical media and Blu-ray discs is the lossless audio encoding. Streaming video services only offer lossy (non-lossless) audio encoding. There is more compression to the audio with streaming video services. For audiophiles and home theater enthusiasts wanting to eek out the best possible sound quality achievable, the physical media format offers gains that are not present with a streaming counterpart.

The release comes packaged in a standard Blu-ray case. The release does not include an o-card slipcover. The release does not include any additional physical swag or pack-in bonuses. A standard edition. The release does not include any additional DVD discs and it does not include a digital copy code.

Unfortunately, the Blu-ray release is close to barebones. The box-set does not have a lot of bonus features. The set could have used some behind- the-scenes, making-of featurettes, audio commentaries, cast/crew interviews, art galleries, and more. Alas, this is an underwhelming aspect of the box- set and in the age of streaming services a nice supplemental package sometimes helps inspire a purchase for collectors who might otherwise opt to simply stream.

Jellyfish Can't Swim in the Night is a charming anime with beautiful animation. The series has incredible production merits. The cast of characters are charming: Mahiru Kōzuki (Miku Itō) and Kano Yamanouchi (Rie Takahashi) are both a huge part of the success of Jellyfish Can't Swim in the Night. The series music by Masaru Yokoyama (Arakawa Under the Bridge) is an important part of the series too. A series that has a fun concept and will appeal to those who appreciate anime about pursuing dreams.
The Blu-ray release provides an impressive high-definition presentation, lossless audio encoding (in both English and Japanese), and a small selection of extras. Collectors may wish to consider a purchase for their collection. Recommended.
