Kodansha announced that it has released a demo version of Sweet Hamster Days for PC via Steam. The company has also narrowed down the release window for this game from Q3 2026 to July 2026.
This game will be a live-action romance sim where the player takes the form of a reincarnated hamster raised as a pet by the Shiratori sisters. Sayaka Tomaru plays the role of the eldest sister Himari, Momoha Takatsuru as the middle sister Futaba, and Shiori Ikemoto as the youngest sister Miyu.
The upcoming full release will feature a story that is being primarily written by Ken Shimomura, who had also worked on titles like Chain Chronicle and Onmyoji. As a hamster, the player will notice that the sisters do not seem to get along with each other. The reincarnated hamster will be able to explore the house and even take actions that could eventually reconcile them.
An English version of the official trailer is available via the Kodansha Game Lab channel on YouTube. However, take note that this trailer originally features Japanese voiceovers, and YouTube will apply its auto-dubbing feature if your site language is set to English.
The demo version of Sweet Hamster Days is readily available to access on PC via Steam. The full release of this game will appear in July 2026 on not only Steam but also Epic Games Store.
