I meant to finish 20th Century Boys! But then I moved to Japan and Europe for a year and a half and half of the manga ended up on the other side of the country. Next time I'm back I need to try to pull it out. I know I have the 21st Century Boys follow-up too.

I do love Urasawa though. Pluto is the only manga of his that I've finished, but it's great, and I loved the Monster anime back in the day.
