Mushishi is a manga series written and illustrated by Yuki Urushibara. It was serialized in Afternoon Seasons Zōkanfrom 1999 to 2002, and in Monthly Afternoon from December 2002 to August 2008. The individual chapters were collected and released into ten tankōbon volumes by Kodansha. Those volumes were localized to North America by Del Rey between January 2007 and August 2010. The series follows Ginko, a man who dedicates himself to keeping people protected from supernatural creatures called Mushi.
Mushishi is set in an imaginary time between the Edo and Meiji periods, featuring some 19th-century technology but with Japan still as a “closed country”. The story features ubiquitous creatures called Mushi that often display what appear as supernatural powers. It is implied that there are many more lifeforms more primitive than “normal” living things such as animals, plants, fungi and bacteria, and Mushi is the most primitive of all. Due to their ethereal nature most humans are incapable of perceiving Mushi and are oblivious to their existence, but there are a few who possess the ability to see and interact with Mushi. One such person is Ginko , the main character of the series voiced by Yuto Nakano in the original version and by Travis Willingham in the English dub. He employs himself as a Mushi Master , traveling from place to place to research Mushi and aid people suffering from problems caused by them.
