Please note: The game itself is currently available in Japanese only.

Rei can pass through walls and slip into narrow gaps. Chris can move objects, smash through obstacles, and fight dangerous enemies. Although they possess completely different abilities, Chris is unable to speak. The two can communicate inside their shared mind only while Rei is possessing her body. Thus begins a strange partnership between a ghost and a girl who do not trust each other. Solve puzzles together, meet residents inspired by extinct creatures, and uncover the secrets hidden beneath a lavish tea party. ■ Story Rei has reached a dead end in life after repeatedly failing to find a job. One night, while working at a museum, she is involved in an unexpected accident. When she next opens her eyes, she finds herself transformed into a tiny white ghost. She has wandered into a mysterious world known as the “Museum of Extinction,” inhabited by people who bear the traits of extinct creatures. With no idea how to return to her original body or escape this world, Rei encounters Chris—a mysterious, bloodstained girl who cannot speak. Cold, violent, and feared by the other residents, Chris is hardly someone Rei can trust. But with nowhere else to go, Rei possesses her body and begins traveling alongside her. Colorful residents inspired by extinct creatures. An unknown world stretching beyond the museum. And something unsettling gradually emerging beneath the splendor of its tea parties. Why are creatures that should have died out long ago living in this world? Can Rei uncover the truth hidden within the Museum of Extinction and find her way home? And where will the meeting of these two lonely souls ultimately lead them? ■ Features - Explore in Two Forms: A Ghost and a Girl Rei can slip into narrow gaps and pass through thin walls.
