Lost/Secret A
SteamSaito, a detective with the Prefectural Police Headquarters, was placed on administrative leave after his reckless actions, driven by a sense of justice, backfired. During his leave, a series of kidnappings began to occur. Saito decided to conduct his own investigation, but this was merely the prelude to the tragedy that would engulf him.

The story is structured across multiple episodes.
The fates of the characters—including whether they live or die—and the five different endings all depend on the choices you make.
A mystery revolving around the culprit and their motive.

Sasaki, a handsome and affable doctor, had been hiding the fact that he lacked emotional depth. One night, in search of a sense of accomplishment, he crossed a line that no human should cross. The plan seemed to be going smoothly, but even those closest to Sasaki harbored secrets he knew nothing about.

A short story. No choices. A linear narrative.
