“Mushi”: the most basic forms of life in the world. They exist without any goals or purposes aside from simply “being.” They are beyond the shackles of the words “good” and “evil.” Mushi can exist in countless forms and are capable of mimicking things from the natural world such as plants, diseases, and even phenomena like rainbows.
This is, however, just a vague definition of these entities that inhabit the vibrant world of Mushishi, as to even call them a form of life would be an oversimplification. Detailed information on Mushi is scarce because the majority of humans are unaware of their existence.
So what are Mushi and why do they exist? This is the question that a “Mushishi,” Ginko, ponders constantly. Mushishi are those who research Mushi in hopes of understanding their place in the world’s hierarchy of life.
Ginko chases rumors of occurrences that could be tied to Mushi, all for the sake of finding an answer.
It could, after all, lead to the meaning of life itself.
Somewhere along the line, Ginko began to question the meaning of his existence. A true mushishi must research mushi, but what did that make him? Were humans also mushi? What about Ginko’s fellow mushishi? Where did he fit in? These questions plagued him for many years, and still do to this day. He had no one to ask for advice. The closest person he had was an eccentric old man with a mysterious illness named Tanukichi.
One day, a Mushishi by the name of Bin showed up at his house, looking for Mushi to research. Ginko reluctantly accepted Bin’s request and began traveling with him.
The travels with Bin brought Ginko knowledge that would change his life: a mantis-like Mushi called “Kusorosu”, which is known as the “Bird-Cutter” due to its insatiable hunger for bird prions (which are parasites that live in bird brains). It was then revealed that Tanukichi was killed by this insect Mushi.
