Thanks for the files tack.
I see that in "Zeruel (Twilight on the beach)" folder you only have intro file and no h-scene file. The player needs the information in h-scene file to sync with data in "info_kamihime" folder so you only need to add the h-scene file for Zeruel and it will work.
About the Eidolons files, I added them in the player and everything work fine with correct name and images so I don't know why you get that problem.
I've updated the script file to fix problem with "Tyr [Awakend]".
Try running "write_config.cmd" again and then run the player with the new script file, if you still have problem with Eidolons, please send me your "config.ini" file.
