This manga came out of left field for me, but I'm so glad that I read it. It tackles some serious real-life issues intelligently through the perspective of an elementary schooler in a way that was nuanced but also appropriate to how someone that age would experience such events. Tying into addressing these topics is the overlying mystery surrounding the veracity of the village's local mermaid folklore. It makes efficient use of its short length to do all of this and executes its storytelling well. Additionally, its art is truly phenomenal in conveying its tone and setting of the story, and is rather unique inthe landscape of shojo and josei manga art that I've seen. Overall, especially given its short length, this manga is a must-read.
