Reception
Anime News Network had four editors review the first episode of the anime: Nick Creamer felt the premiere suffered from "structural, narrative, and aesthetic issues" that prevent it from capturing the same rural Japan aura as Laid-Back Camp and displayed "tonal incongruity" with its subject matter and the Breakwater Club's hostile treatment towards Hina; Rebecca Silverman was also critical of the fishing club's cruel tactics on Hina but was commendable for their faithful portrayal of "the attitude of small coastal towns" and their various activities, concluding that fans of "slow-paced fishing stories" will enjoy it but may not attract others beyond its targeted genre audience; Theron Martin wrote that: "[T]echnical merits here are decent but nothing exceptional, so the question here is going to be whether the "cute girls" appeal can draw in those not interested in the hobby. In that regard, I put it on about the same level as Tamayomi: might be watchable, but being at least receptive to the hobby in question will matter." The fourth reviewer, James Beckett, praised its "cozy slice-of-life charm" for carrying a "soft and inviting" art direction and a likable cast that will bring Hina out of her ichthyophobia as the story progresses. Beckett added that he won't watch any further, but concluded that: "It will, however, provide much edutainment for folks who either have fond fishing memories of their own, and also for anyone who is interested in learning more about the craft with the help of a bunch of nice anime girls."
