This episode is imediately notable for a distinct change of direction. Mushishi usually begins with Ginko wandering about beautiful landscapes, finding his next job and meeting new people, here the first 13 minutes are told as a flashback, in which tragedy inevitably occurs. The latter half of the episode is all about finding true emotional redemption.
Indeed this was hardly a typical Mushishi episode at all since the actual mushi creatures play what amounts to a very insignificant part (though as ever, it’s symbolic of the emotion felt by this week’s main character- a mushi that yearns for it’s homeland). That said, Mushishi’s strength lies in compelling human drama and yet again, it delivers with an emotional and heartfelt payoff. It wasn’t as flashy, or as shocking as this series has been in the past but still, the way this episode glided through such tricky issues as depression and guilt was nothing less than outstanding.
I know full well that I haven’t sufficiently provided you with a plot synopsis for this episode but frankly, it isn’t needed; just understand that this was a brilliant episode of anime and another series highpoint for me.
