Ohkuma Minoru knows a lot about animals and insects, and her fascination with living things has led her to keep a research notebook of her daily observations. That fascination has now turned toward her classmate, Komichi. Komichi knows a lot about various creatures due to her country upbringing, and she takes notes on things that interest her. After learning that they have these things in common, Minoru and Komichi decide to observe their classmates together. Minoru believes that acting in secret is important when observing living things, but Komichi, the only student at the school who wears a sailor uniform, tends to stand out and isn't the best at being secretive...
