Ginko

Ginko is the main protagonist from the Mushishi anime.

Ginko, whose real name is Yoki, solves Mushi cases. He rarely comes back to the same show location more than once, to reinforce his 'wanderer' status.

Abilities
He's one of the few people with a "strange" or "bewitching" quality known as  youshitsu. It means he can see mushi, where as most people cannot.

He's also damn smart, well studied in both mushi and ordinary plants and natural phenomena. His travels have also taught him more than a thing or two about how to deal with people. He's able to talk them down from nearly every kind of emotional height, and people seem to instinctively trust him.
