Jesus, the things some people can come up with. I read the second one and just sat there for a second, staring at the computer screen in awe. Creeped the hell out of me, but was amazing.
The post story was really random XD. The Enigma of Amigara Fault was very intruiging but I didn't like the secret behind it tbh. Gyo was below average for me but it really was disturbing to see the people become something like those :p
I've been coming to enjoy Junji Ito's work more, but The Enigma of Amigara Fault still freaks me out that I can't bring myself to go back and read it again without chickening out.
