The insects here are neither animals nor plants, nor are they different from microorganisms and fungi. They are things closer to the original ecology of life. These things are collectively called "worms". Their form and existence are both ambiguous. When the worlds of humans and insects overlapped, strange phenomena occurred that surpassed human intelligence. Only then did humans begin to know of their existence. The so-called life does not exist to threaten dissidents. However, each exists in its own form - as the "insect master" who connects such "insects" and humans, the protagonist Eingu constantly encounters various people and the insects related to them during the journey. The characters appearing in each episode are different and endless to read.
