Hayao Miyazaki can't stop.

The 72-year-old filmmaker and artist announced plans to retire from directing at Studio Ghibli earlier this year, but that isn't keeping him from writing and illustrating a new manga series about samurai in Japan's Warring States era. He hasn't even been paid for the currently unnamed work yet. Japanese TV network NHK snagged some footage of Miyazaki working on the comic, and you can take a look at some screenshots. So far, it seems as rich and detailed as anything he's ever worked on.

 

Miyazaki's final feature film through Studio Ghibli, The Wind Rises, is set for release in the United States in February 2014. No word yet on when fans -- in Japan or the US -- will be able to read his upcoming samurai manga.
