She is so supportive that she'd like to observe various species of bugs with the son and always accompanies him to go up to the mountains with other bug enthusiasts.

However, many of Ran's peers fail to understand his obsession with bugs which they find gross and scary.

Regarding that, Ran says: "Everything is neither good nor evil. As for bugs, there's no difference either. Good or bad, it's all made up by human beings. That's the philosophy of nature."

Ran's story has been recorded in a six-episode documentary, titled Little Giants, which aims to film children who have talent in sports, arts, natural science, technology, music or other fields to see how creative they can be as they seem to have found a life passion at a young age. The episode on Ran is titled Philosophy of Nature.

Other children in the online series include a 9-year-old boy who is fascinated with composing and playing music in a band, a 14-year-old racer who is the only female motorcycle rider in her team and two high school students who work as partners to compete in international robotics contests.
