|hmm... That's what I was thinking too, it says Psychometrer Eiji, 第一部(first part) 完(end).
Spoiler (highlight to view)
the ending introduces the possibility that a sequel COULD be made, but lots of movies and stuff end that way with no sequel, so maybe not
(that is only tentatively a spoiler... it depends on what you consider a spoiler, i don't explicitly say anything about the events, but just to be safe...)
on the covers/inside flaps, there is something that looks like an "also published by us"/"more from the same author" list, and it says: Psychometrer Eiji mania (then some kanji i don't know). I don't know what that is, though.
I have a recent paranoia about my comments disappearing... Odd, right?
