The 3rd Chapter, I enjoyed. XD Ahhh Suan~<3 He's still my favorite character. The Songokuu thing and how that was solved is insane and clever and I love it. XD Though...it probably wouldn't make much sense unless you're familiar with the characters of Journey to the West.
So overall, I'm still unimpressed with Shanmaki as a whole, but it has its moments.
(Shanmaki = Shanghai Youma Kikai, btw. XD;)
