Dang, that first page art without the pupils look so uncanny. I remember this being one of the more darker episodes and also for Mitsuo actually using his brain to survive a serious situation.
It would be interesting to see a more serious but not necessarily darker version of Perman where intelligence and street smarts matter with maybe some horror, tension and big steaks on the line.
The copyright would last till 2067 but there might be some doujins out there.
