Pop Elephant Studio

Pop Elephant Studio's psychological horror adventure game, Ore no Kaitai-shi, launched on Steam at 790 yen with a 10 percent launch discount. The game follows Hector, a prince of a fallen nation, and Matvey, his adjutant who is also his uncle, caregiver, and "mama," as their codependency in a rented apartment turns abnormal. Play is point-and-click, and the order in which the player investigates changes what is remembered. Japanese display and full voice are supported, and a demo is live.

Before the launch, the studio released a demo for the same project under the title My Dismantling History. That demo runs about 30 minutes and covers a prince who loses everything and begins a life of exile with his uncle. At that time, the full game was scheduled for the third quarter of 2026.

The two stories establish the game's subject and release. The June story describes the exile premise and a 30-minute demo. The September story confirms the Steam launch at 790 yen with a 10 percent discount, names the characters Hector and Matvey, and specifies point-and-click play, Japanese display and full voice, and the investigation-order mechanic. The final title on Steam is Ore no Kaitai-shi; My Dismantling History was the title used for the earlier demo.
