This is a walkthrough for the English version of Dies irae – Amantes amentes. The Japanese walkthrough it’s based on can be found here.

Recommended route order: Common (Chapters 1-6) → Kasumi → Kei → Marie → Rea

Follow the above route order, trust me. Otherwise you’ll ruin the story for yourself.

Okay, so here’s the thing. Before you start the game, you’re shown this screen:

If you’re a first-time player, make absolutely sure to pick “New Game” on the left. If you pick any of the heroine buttons on the right, the game will lock you onto said routes regardless of your dialogue choices.

Note 1: The Other Stories can be accessed from the main menu, under (you guessed it) Other Story. One thing to note is that “Omnia vincit Amor” is essentially a Marie route epilogue, while “Nihil difficile amanti”, in a similar fashion, provides an epilogue for Rea’s route. As such, I would recommend reading those two extra stories immediately after finishing their respective routes. As for the other three side stories, I’d recommend reading “Wehrwolf” after finishing Kasumi’s route, then “Die Morgendämmerung” and “Verfaulender segen” after completing Kei’s route.

Note 2: Rea’s route has two endings. Go for Ending 1 first (“danced to the… etc.), then Ending 2 (…sought the truth) afterwards for the optimal reading experience. Also, make absolutely sure you follow the walkthrough very closely. Particularly in Rea’s route, you need to pick “Look for Rusalka”, “Trust Rusalka” and “Rescue Rea Himuro”, otherwise you won’t see some very important optional scenes.

Note 3: You can press F7 in-game to immediately jump to the next choice, while F6 will take you back to the previous choice.
