‘Vivy: Fluorite Eye’s Song’ (2021): A Review

An Emotion-Provoking Anime

Created by Tappei Nagatuski and Eiji Umehara, Vivy: Fluorite Eye’s Song is a science fiction drama anime series that follows the first autonomous AI, Diva. She is a songstress AI whose mission is to make everyone happy with her singing. When Matsumoto, an AI from 100 years in the future, arrives, Diva is roped into helping prevent the future where AI eradicates humanity. Over the course of 100 years, Diva and Matsumoto have to fix the singularity points that lead to the war between humans and AI. Wit Studio produced the series while Shinpei Ezaki directed it. The series first ran from April 3, 2021, to June 26, 2021.

A Hundred-Year Journey

With 13 episodes running at about 25 minutes each, Vivy: The Fluorite Eye’s Song is the perfect length for a binge-watch. Even with a tight episode limit, the anime has an easy way to keep up with plot pacing. Characters are sure to mention how long the time skip has been between episodes in a way that the comments fit into the story. The series could be described as an anthology in the way it follows the same characters with a core goal but different scenarios. It may not seem like it on the surface, but the anime is action-packed, occasionally bloody, and filled with a rollercoaster of emotions. Most episodes are tragic in the most beautiful of ways.

The anime frequently sees Diva (usually referred to as Vivy, and how she will be referred to in this review going forward) question how to sing with all of her “heart.” Music can capture raw emotions and convey them to anyone, no matter if they know the language. Seeing an AI character question this when she has no real heart draws the viewer in. It’s part of what makes following Vivy on her mission so fulfilling. This one element helped turn Unpredictable and filled with joyful and melancholic emotions; the series is addicting. Every fight scene or dramatic moment will leave viewers unable to stop at just one more episode. 

Robots and Humans Together

Atsumi Tanezaki (Spy x Family) plays the original Japanese voice of the titular character in Vivy: The Fluorite Eye’s Song. While watching or reading anything with an autonomous AI character, how they act can feel off at times. This was never the case with Tanezaki’s Vivy performance. Any reaction or change felt natural for a being who’s finally learning to grow out of her one role in life. Viewers get the pleasure of growing alongside Vivy in her 100-year mission. The secondary protagonist Matsumoto, who is voiced by Jun Fukuyama (Suicide Squad Isekai), is hilarious.

The interactions between him and Vivy sometimes have the energy of fighting siblings. Every character has something about them that makes them feel important to the viewer, even if they’re a main side character for only an episode or two. The AIs gain the most from this, each prominent AI character having a different personality and impact on the story.

Stunningly Beautiful Visuals

Fans of Attack on Titan or Spy x Family may recognize the animation style in Vivy: The Fluorite Eye’s Song. Wit Studio, the same studio that produced the first three seasons of Attack on Titan and Spy x Family, is behind the stunningly breathless animation in this series. It is filled with gorgeous and sometimes morbidly beautiful imagery. Vivy, in particular, gets some close-ups and imagery of what she sees through her fluorite eyes (get how it’s related to the title?) that are near high-definition art. One thing to nitpick is the speed of the animation, particularly during action scenes. Almost every episode has an action-packed fight, but sometimes the animation moves too fast to truly appreciate just how breathtaking each character’s motions are. 

The soundtrack helps make the series, turning an overused plot, unique. While the anime isn’t wholly focused on singing, a good amount of it still drives the plot forward. Meant to be an emotion-provoking anime, Vivy: The Fluorite Eye’s Song seamlessly incorporates Vivy’s and other characters’ singing into each episode. The opener is a must-watch for every episode due to how the animators incorporate the opening title to a scene in some episodes. Artist Kairi Yagi does a thrilling job of performing the opener, “Sing My Pleasure,” and every other song Vivy sings every moment as her singing voice actress. Viewers are sure to pause the first time they hear her sing and feel the raw emotion behind her voice and lyrics. 

An Overlooked Work of Animation

Anime isn’t everyone’s cup of tea, but Vivy: Fluorite Eye’s Song is an excellent series for anyone looking for a day-bingeable, emotionally filled journey. With an intriguing premise, well-rounded characters, and beautiful animation work, Wit Studio has outdone itself. The stunning visuals alone are enough to warrant a watch, from the nail-biting fight scenes to the sometimes uplifting, sometimes melancholic singing moments. The anime is not just about singing; it’s far from it. Vivy: Fluorite Eye’s Song is an anime anyone can take pleasure in viewing; parents just need to be mindful of the violence before letting young kids watch. It is truly an underrated anime of its time.

Vivy: Fluorite Eye’s Song is available to stream on Crunchyroll. Take the time to follow Vivy in her mission to make everyone happy with her singing. It’s more than worth the experience.
