This guy posts a lot about anime and what not. He just put up this video about Toriyama and Dragon ball thought you of all people would find it interesting. The ask robot wont let me put in the link, but it's called "The Genius of Dragon Ball" by super eyepatch wolf on youtube. check it out if you have a chance.
I was thinking this was some shameless plug or something, but I like it! He talks about the history of Toriyama’s work, and how Dragon Ball was thought up. It also focuses on Toriyama himself rather than just being like ‘hurr durr dbz awesome’ like I figured it’d be like.
