This cube craft paper toy is Ginko (real name Yoki), the main character who is followed throughout the Mushishi manga series solving mushi cases, this paper craft was created by alonso jacobo. Ginko appears to be a very serious person on the outside, but he treats humans with respect and stresses that the mushi are not evil, but merely trying to survive like everyone else. He rarely comes back to the same show location more than once, to reinforce his 'wanderer' status.
Ginko has white hair and an unearthly green eye, and has been like this ever since he was a child after he was affected by a mushi. He also wears more modern clothes compared to other characters, by wearing slacks, a button up shirt, and occasionally a trench coat.
Ginko during his younger years before being affected by the Ginko Mushi had dark hair and black eyes. He had a darker skin tone. [Source: wikia]
