Crayon Shin-chan, Volume 3
No matter what you though of the man's work, there's an unmeasurable sadness at the passing of Yoshito Usui.
The body has been correctly identified via dental records, and it appears he died from a collapsed lung and other complications on September 11th.
The 51 year old mangaka leaves behind a family, and hopefully the knowledge that he died while doing what he loves is of some condolence to them.
Though, on a more positive note, Yoshito had already completed the next two installments of the Crayon Shin-chan manga,
which will see publication through Novemeber. For a man so silly, I'm sure he'd prefer us not be so solemn. While the show isn't currently running on Adult Swim, you can see a few episodes streaming directly from FUNimation.
