by STARTails☆ (Reina Kondō, Tomomi Mineuchi, Maria Naganawa, and Ayasa Itō) and the ending theme is "Kaze no Koe wo Kikinagara" (風の声を聴きながら, While Listening to the Wind's Voice) by Sangatsu no Phantasia.

[17][18] Anime News Network had four editors review the first episode of the anime:[19] James Beckett commended the pastel colors and intricate character animation for making up the overall aesthetics to appeal to its target audience but was heavily critical of the thin setup and bland characters being similar to every other all-girl slice-of-life series; Rebecca Silverman saw some promise in the series due to Tomomi Mineuchi's naturalistic performance as Eiko and an exploration into Hana's backstory and shy personality but felt the premise was put behind in favor of overly cute girls talking and having nonsensical adventures, calling it "the palest of several similar shows to debut thus far" in the season; Theron Martin gave credit to director Hiroyuki Hashimoto for competently adapting a piece of fluff with an intriguing gimmick involving Hana's situation but felt it was a lesser offering in comparison to similarly, stronger-themed slice-of-life shows filling the season.

The fourth reviewer, Lynzee Loveridge, was put off by the infantile cast of high school girls having "caricatures of female relationships" with uninteresting topics and the overly sweet art style encompassing the episode without a hint of realism to ground it.

[19] Vrai Kraiser of Anime Feminist, reviewing the show's first episode, was critical, saying they felt uncomfortable after watching the first episode, that the characters feel "manufactured to be pwecious and kyoot", argued that the series is "extremely alienating...hollow and dead-eyed," and said that fans of moe "deserve better" than the series.
