Unable to hook to games which create multiple exe

[Gothmog19]

Several times now, i have encountered rpg-games which create multiple exe. Like this one:
http://www.dlsite.com/ecchi-eng/work/=/product_id/RE206421.html

I tried using ITHVNR and attached all exes, checking each of them, but they don't offer a single option. If i try the same with agth the result is the same. And if i use the /X3 option for agth i get some options but not a single one is text related.

Help would be very much appreciated.
