Nakano Personality Transplant Laboratory Hands-On Reveals Body-Switching Mystery Loop
The possession mechanic is a structural bet, not a cosmetic one: who you inhabit decides which rooms and evidence you can reach, so the full version's promise of choosing your target turns one investigation into several different ones.

At OSAKA INDIE GAMES SUMMIT 2026 on October 3 and 4, Menya Spice Tokyo Branch showed a demo of Nakano Personality Transplant Laboratory, a PC mystery adventure set for release in 2027. After a researcher disappears, the story advances in a 15-minute loop. Players possess suspects to widen what they can explore, gathering clues for meetings presided over by a researcher named Oliver.
Nakano Personality Transplant Laboratory runs on a 15-minute loop, the same short-scenario structure the team used in the 2025 adventure game Aiai Kissaten. In the demo, protagonist Mamiya Kamome boards a research ship and meets a crew of researchers, among them Umekoji Ayano, Oliver, whose head is a glass container holding a mouse, Yotsuya Yu, and the taciturn Kakiike Ko. When Kakiike is attacked, the player investigates and presents evidence in a meeting overseen by Oliver.
Possessing Umekoji changes more than the sprite on screen. Her height lets the player reach high shelves, she can enter the women's bath, and she can enter the Umekoji Group laboratory, which only group members may use. The full version will let players choose whom to possess, and each host yields different information.
