Ceramic · Stainless Steel · Neurotransmitter

A short interactive novel. There is no "truth" in this game. This is not an armchair detective story—it is simply about a girl in a stall. You will advise the protagonist, determine how she perceives everything around her, and witness her ending.

As stated in the overview, the playtime for this work is around 30 to 60 minutes—not including the time needed to unlock all endings.

Our protagonist is a girl named Utsu-chan, and you will act as her friend and guide. What you do together is more than just casual chat—it carries a deeper significance.

The game spans five days. Each day, you will hear rumors about different girls. "Truth" doesn't matter—all you need to do is decide what kind of voice to respond with to Utsu-chan inside the stall. Your accumulated choices will lead you to different endings.

This is a story about loneliness, misunderstanding, fragile emotions, and the bonds between girls—set among ceramics, stainless steel, and neurotransmitters.

・Warning:

This work contains descriptions and expressions that may be disturbing, including but not limited to school bullying, social anxiety, depressive tendencies, and inappropriate behavior by minors.

All content represents the protagonist's subjective experience and is not intended to encourage or glorify any such actions.

*This game currently supports Chinese only. English localizations are planned and will be added via a free update shortly after the initial release. Since I'm a solo developer, the translation will follow a bit later — thank you for your patience! The game is completely free, and once new languages are added, you'll get them automatically with no extra steps.
