Dies irae ~Amantes amentes~ - Official Illustrated Guide

During Dies irae's World Emanation Project Kickstarter, an official illustrated guide was distributed to certain backers as part of a stretch goal reward. But now it's available in PDF form!
It's a special booklet created by splicing together four original booklets that were released in Japan.

This DLC boasts over 200 pages of character profiles, rough design sketches, CGs from the game, illustrations that went unused, and more!
If you're a fan of Dies irae and you want to learn more about its world, this is the pick for you.

Note: The DLC data will be added into the game's installation folder. A folder titled "Artworks" containing the PDF data will be added.
