A city without emotion. A feeling is the only clue.

In the controlled city of AUREX, emotion has been ruled inefficient — monitored, suppressed, and engineered out of daily life. You are SOLDA, a rookie special investigator of the Central Order Department. Your only edge is an emotion scanner that visualizes the feelings people are trained to hide. In a city that erased emotion, the smallest tremor becomes the loudest clue.

SOLDA is a story-rich sci-fi mystery visual novel about investigating crimes — and confronting what it means to feel at all.

The story

Emotion is treated as a malfunction — but it never truly disappears; it only hides, waiting to surface like a bug in the system. As SOLDA follows each case deeper, she begins to feel what she was trained to forget, and the questions stop being only about the crime. Who benefits from a city without feeling — and what is the cost of taking it back?
