Invasion from within! The city of Mangetsu is under attack, besieged by nightmares, creatures slithering out from Dream Worlds parallel to our own! It's up to Yatsuha and her new allies at Yamanashi Energy Labs to drive back the intruders, seal the Dream Worlds, and preserve the city's peace!

Battle the nightmares in classic turn-based combat! Your team of Dream World investigators draw upon skills from backgrounds ranging from martial artist to shrine maiden, and supplement their natural abilities with the powers granted by mystical Guardian Stones.

Equip Guardian Stones to gain new skills, passive abilities, and elemental affinities! There's no need to commit to a build—swap out your Guardian Stone to suit the situation! Each investigator has their own unique assortment of stones to collect and wield, so no two characters are the same.

Explore the city of Mangetsu! Yatsuha's hometown is a hotbed of supernatural activity, and mysteries and rumors abound. Exploration and investigation will lead you both to powerful new equipment and vicious new foes.

Explore a modern Japanese city and the twisted Dream Worlds that lurk on the boundaries of our reality.
