■ A New Sensation: Live-Action Romance Sim where you're pampered by three sisters from a hamster's perspective!
This game is a live-action romance simulation with an innovative concept: the protagonist, who has been reincarnated as a "hamster," is kept by three beautiful childhood friend sisters and is pampered to the extreme with a strong sense of realism through live-action footage. The three gravure idols playing the heroines are Sayaka Tomaru, Momoha Takatsuru, and Shiori Ikemoto. Players will experience a thrilling cohabitation with the three sisters from the perspective of a hamster, either from inside a cage or in their hands.

In Japan, it was also featured on "Noda Kuri no Yabo" (Tokyo MX).
After that, it encountered a mishap where its Steam store page was temporarily deleted, but now the prospect of its release has been safely established.

Leading up to the main release in July 2026, participation in the limited-time event "Steam Next Fest" (June 16 - June 23, Japan time) held within the Steam store in June has been decided.
