## Reception

The anime series' first episode garnered generally positive reviews from Anime News Network's staff during the Spring 2024 season previews. James Beckett gave high praise to Yoru and Kano's "immediately compelling relationship" and the overall production for displaying the characters' "weight and heft" during the musical and dramatic scenes. Richard Eisenbeis praised the overarching plot involving Yoru's crippling peer pressure and her interactions with Kano, saying "all signs point to this being a journey worth watching." Rebecca Silverman was critical of the show's "meandering conversations" over "highly symbolic images" and unsure if it can sustain this storytelling style, but was optimistic for Yoru's artistic rediscovery and relationship with Kano. Nicholas Dupree was critical of the show spelling out its characters' problems by hammering them with "blunt metaphors", but gave praise to the visual artistry for its nighttime Shibuya backgrounds and showing "elastic vibrancy" in the character designs, saying "Jellyfish is playing with ideas and themes that I love and clearly has the artistic ambition to make the journey a pleasant one. I can forgive a few fumbles when a show is this earnest and delightful."
Zhang Yi from The paper stated that after the "stunning" first episode, "the plot of the whole anime steadily declined in quality." He criticized the anime is trapped in an awkward position of being "dreamy, yet not dreamy enough" that failing to deliver pure relax while rendering the narrative conflicts overly superficial, describing the first episode of the series as a "fraud".
