I've been unable to replicate your error so you'll either have to download what's missing from the attached GIF archive or wait for someone else to solve the problem. Check post #674 for instructions on extracting files from image/GIF archives. Run 0_download_json.cmd, 1_download_assets.cmd, 2_build_rpy.cmd, and 3_write_config.cmd after pasting the needed files and/or folders into '[DMM] Kamihime_Player-1.0-pc\game\dmm'.
The asset folder names can be found in 5410.json, 5411.json, 5418.json, and 5419.json and the filepath is '[DMM] Kamihime_Player-1.0-pc\game\dmm\info_kamihime'.
Edit 2: Updated to include both DLpy scripts, the troubleshooting guide (mentions the newest DLpy script location), attached the DMM files for Charlemagne [Love Teacher], [Memorial0021] Baal, and [Memorial0022] Khonsu. I don't have the portraits or thumbnails for the Charlemagne skin or the Baal memorial and will update the archives when I get them. The previous DMM files are on post #833.
Edit 3: Added the images for Charlemagne [Love Teacher] and [Memorial0021] Baal to the attached GIF archive.
Edit 4: Updated to include both DLpy scripts and attached the DMM files for Edison [Dream of Dawn], Dakki [Heavenly Awakening], [Memorial0023] Cybele, and [Memorial0024] Receptionist.
