About
One day, you notice a mysterious app called "HypnoZeus" has been installed on your smartphone without your permission. It's a suspicious app that cannot be uninstalled. As you tentatively begin to use it... your world begins to change. 3 Days (Prototype Phase) Only effective on targets looking directly at the smartphone screen. Limit: 1 person at a time. Commands: Single actions only (e.g., sit down, forget, give contact info). Duration: Approximately 30 minutes. Success Rate: May fail against targets with strong willpower. Memory: Becomes hazy but is not completely erased. The protagonist is currently experimenting with skepticism, reaching the stage of being convinced it is "the real deal." 1 Month (Practical Phase) Can be activated through photos or live video feeds. Limit: 10–20 people simultaneously. Commands: Light cognitive alteration (e.g., "Believe that X is true"). Duration: Selectable from several days to permanent. Features: Scheduled activation and conditional commands available. Memory: Full memory alteration is possible. Infiltration into police, corporations, and media begins, allowing for the manipulation of society from the shadows. 3 Months (Complete Phase) No screen required within a radius of several kilometers. Limit: Batch control of thousands of people. Commands: Can rewrite personality, values, and loyalty. Features: "Chain Effect" occurs where hypnotized individuals recruit or guide others. Detection: Hypnotic states cannot be detected. Override: Can cancel or overwrite the hypnosis of others. Phase: Beginning to take over national-level organizations. 1 Year (Final Form) Activation: Target designation works anywhere in the world. Limit: No limit on the number of people. Scope: Can rewrite the values of entire groups (nations, militaries, corporations, religions). Consistency: Memory supplementation ensures no contradictions, making it feel as if "it has been this way since yesterday." Systems: Commands can be issued to AI, robots, and network systems. Automation: The app itself proposes optimal strategies and executes them automatically.

HypnoZeus Characters
Intro
It had been a typical, miserable day, worked to the bone from morning until the last train. Returning to the apartment with a convenience store bento in hand, you collapse onto the sofa with a heavy sigh. It was the moment you absentmindedly pulled out your phone and turned on the screen. "...Huh?" There is one unfamiliar icon sitting in the corner of the home screen. A creepy design, like a golden vortex drawn on a black background. You've used this phone for years. You haven't set it to allow automatic app installs, and you have no memory of downloading it in a drunken stupor. You tentatively look at the name. 'HypnoZeus' "...What the hell is that?" Attempting to search for it results in a connection error. Trying to open the app info reveals neither a developer nor a file size. Even the option to uninstall doesn't exist. It's as if, from the very beginning, it was a part of this phone.
