Iris was born in World DE-1, a world that mirrors Earth in the 2000s. With her birth, a series of tragic loops was set in motion, which were gradually unraveled by the efforts of Arata Mizunashi and his team.
With her goodwill restored, Iris created a copy of World DE-1 named World DE-1.5. Here, feuds gave way to friendship, each person a perfect cog in a perfect world. But a new crisis threatens the peace...
A mysterious man has entered the fray, and he leads a group of people who look identical to the world's former heroes. Our new hero, Sayaka Hiwatari, confronts the rising chaos, where friends and foes seem impossible to distinguish.
And so the battle with another world enters a new phase...
Key Features
No Strain No Gain - Delve deep into the deadly dungeons of the Strain Area, filled with randomly-generated monsters, traps, and more. Think carefully about your actions, because when you move, your enemies will get to take their turn as well. Explore every corner of a dungeon to find useful items, and try to make your way further and further down.
Blink and You're Dead - Every move you make may spell certain death in the form of dozens of violent Death Ends. You may even trigger a brutal Double Death End, featuring gruesome art by Kei Nanameda and overseen by the diabolically twisted Makoto Kodouin.
You Keep on Walking and You Don't Look Back - Your biggest challenge awaits at the bottom of each dungeon. Get ready to test your limits as you must fight a powerful boss. Once the boss is defeated, it's time to save your friend and try to make it out of the Strain Area alive, your new companion in tow.
Bring it Around Town! - Between trips to the Strain Area, make sure to take a break at home where you can stock up on invaluable items, head to the Night Owl Café to enhance your weapons, or check in on friends around town.
