I'll preface with my recommendation, this show is good, it's worth a watch. It's short and sweet too! But, in my opinion, it's missing some kind of tang. I think it would've done wonders if it was longer with more buildup for the end. And if the protagonist's progression was better visualised. The characters as cute as they are can be irritating at times. I really liked the adults and how similar but different they are compared to the kids. I think they should've had more screen time. My conclusion goes as follow, this anime would probably have been miles better with more episodes. I hope it'll be renewed for a second season, it definitely deserves it.
