This game can be played in English or Japanese. Audio is in Japanese, and the interface text and subtitles are available in English and Japanese. — The terror comes for those who watch. — This is a true ghost story as told by a person known only as “Y”. It centers on a series of interviews conducted to discover the truth about a “listen-at-your-own-risk urban legend.” It is said that anyone who hears the legend will be cursed. And a “malevolent presence” seems to lurk within those interviews... This project reconstructs the interviews as 360° videos, and presents them as live-action interactive content. — Video noise signals that the malevolence is nearby. — If you watch these videos even a single time, you must look for all the sources of malevolence contained within. That’s the only way to escape the curse. And when you do find them all, “something” will happen...

No Choices But Deduction.      No Game Over.      No Multiple Endings.      Your choices will change neither the story nor the movement of the celestial bodies.      The only thing you can do is pull the trigger—and deduce.      "Crimsooon Sun" is a short mystery adventure designed with a singular concept: "A mystery game you can play with the same level of focus as reading a detective novel."      The story takes place in Shirase, a regional city in the Tohoku region. It begins with the return of Mio Fujimaru, a university student who had been missing for nearly six months. She remains silent about her disappearance. However, a video exhibited at the university festival reveals a chilling sight: Misao being pushed down a wedding aisle in a wheelchair by a mysterious "the Faceless Man," while "the Dual Suns" are reflected in the window.      This is a mystery "novel" adventure. When reading a detective novel, one doesn't always have a perfect, logical solution like the detective in the story. Often, we rely on vague intuitions:      "Something about this statement feels like a lie."      "This person seems suspicious."      "This description might be related to a trick."      Such intuitive reasoning often clashes with traditional game systems that require picking the "correct" choice to proceed.      Inspired by "Mikagura Shojo Tanteidan" (Mikagura Girls' Detective Agency), a classic title released for the PlayStation by Human Entertainment, this game cuts away all unnecessary choices and branching paths. Instead, you "pull the trigger" whenever something piques your interest. With the 26 bullets of information you’ve gathered, your only task is to deduce the truth.      Defy the sun with twenty-six bullets.      Even if the revolution of the heavenly spheres cannot be stopped.
